129-477: The Kurtis Sport Car (KSC) is a two-seat, aluminum -body sports car designed by Frank Kurtis and manufactured by Kurtis Kraft in 1949 and 1950. Built with numerous components (including the chassis and V8 engine ) from a 1949 Ford , the KSC was built as both a production car and a kit car . It was sold at a base price of $ 3,495. It could cost up to $ 5,000 with options, which was approximately $ 1,000 more than
258-543: A Mercury -powered sports car just before World War II and similarly customizing a 1941 Buick in 1948, both of which generated serious interest and large offers from businessmen, Kraft decided to build what would become the Kurtis Sport Car (KSC). He envisioned it as a new type of sports car with American power, European handling, and modern styling. The KSC was designed as a two-seat, aluminum -body sports car by Frank Kurtis. A two-door convertible , it had
387-453: A front-engine, rear-wheel-drive layout . The prototype KSC was designed in 1949, and built on a 1949 Ford chassis. It was powered by a six-cylinder, supercharged Studebaker engine. The only instrument mounted on the prototype's dashboard was a tachometer , although the car also featured a telescoping steering wheel . Low-slung in appearance, the prototype was built with fiberglass body panels , removable plexiglass side windows, and
516-426: A longitudinal engine layout and rear-wheel drive (or all-wheel drive). However, V8 engines have also occasionally been used in transverse engine front-wheel drive vehicles, sometimes using closer cylinder bore spacings and narrower cylinder bank angles to reduce their space requirements. The classification of 'big-block' or 'small-block' refers to the engine's external dimensions and does not necessarily indicate
645-491: A precipitate of aluminium hydroxide , Al(OH) 3 , forms. This is useful for clarification of water, as the precipitate nucleates on suspended particles in the water, hence removing them. Increasing the pH even further leads to the hydroxide dissolving again as aluminate , [Al(H 2 O) 2 (OH) 4 ] , is formed. Aluminium hydroxide forms both salts and aluminates and dissolves in acid and alkali, as well as on fusion with acidic and basic oxides. This behavior of Al(OH) 3
774-525: A "less classical sound". This name persisted: although the -um spelling was occasionally used in Britain, the American scientific language used -ium from the start. Most scientists throughout the world used -ium in the 19th century; and it was entrenched in several other European languages, such as French , German , and Dutch . In 1828, an American lexicographer, Noah Webster , entered only
903-543: A 0 to 60 mph time of 15.3 seconds, and a quarter-mile time of 20.0 seconds. After buying the rights to the KSC in 1950, "Madman" Muntz proceeded to create the Muntz Car Company and redevelop the car into what eventually became the Muntz Jet . He lost money on the endeavor and ceased production in 1954. By 1951, just two years after the KSC appeared on the cover of Motor Trend , Harley Earl had created
1032-544: A 2.5 L (153 cu in) V8 engine. BMW's first V8 engine was the 1954–1965 BMW OHV V8 engine , a petrol engine with overhead valves and all-aluminum construction. The company resumed production of V8 engines in 1992 with the BMW M60 aluminum double overhead camshaft engine, and V8 engines have remained in production until today. BMW's first turbocharged V8 engine was the 1998–2009 M67 twin-turbocharged diesel engine. The first turbocharged V8 petrol engine from BMW
1161-525: A 5.6 L (340 cu in) Chrysler LA engine and built on the chassis of a 1950s Chrysler Imperial. The 1934–1938 Tatra 77 rear-engined sedan was initially powered by 3.0 L (183 cu in) petrol V8, which was air-cooled and used an overhead camshaft that operated the valves using a 'walking beam' rocker arrangement. This model line continued until 1999 when the Tatra 700 ended production. Tatra also produced diesel V8 truck engines from
1290-560: A 60-degree V-angle, since it was derived from the 60 degree V12 Rolls-Royce Meteor which in turn was based on the Rolls-Royce Merlin V12 engine . Other V-angles have been used occasionally. The Lancia Trikappa , Lancia Dilambda , and Lancia Astura , produced 1922–1939, used narrow angle V8 engines (based on the Lancia V4 engine ) with V-angles of 14–24 degrees. The 1932 Miller four-wheel drive racing cars used
1419-499: A Swedish chemist, Jöns Jacob Berzelius , in which the name aluminium is given to the element that would be synthesized from alum. (Another article in the same journal issue also refers to the metal whose oxide is the basis of sapphire , i.e. the same metal, as to aluminium .) A January 1811 summary of one of Davy's lectures at the Royal Society mentioned the name aluminium as a possibility. The next year, Davy published

The Holden V8 engine was used in various models, including the Kingswood, Monaro, Torana, Commodore, and Statesman. Versions tuned for higher performance were sold by Holden Dealer Team and Holden Special Vehicles , including versions stroked to up to 5.7 L (350 cu in). The Holden V8 engine
1677-591: A V8 engine was the 1965 Chrysler Valiant (AP6) , which was available with an American-built 4.5 L (273 cu in) Chrysler engine. The first locally designed V8 Ford was the 1966 Ford Falcon (XR) and the first V8 Holden was the 1968 Holden HK , both using engines supplied by their parent companies in the United States. The first V8 engine to be mass-produced in Australia was the 1969–2000 Holden V8 engine . This cast-iron overhead valve engine used
1806-464: A V8 engine was the 1988 Audi V8 luxury sedan. Its first model to use a V8 diesel engine was the D2 A8 3.3 TDI in 2000. The first V8-engined Alfa Romeo road car was the 1967–1969 Alfa Romeo 33 Stradale mid-engined sports car, of which 18 were produced. This was followed by the 1970–1977 Alfa Romeo Montreal front-engined sports car. The engines for both cars are based on the 90-degree V8 engine from
1935-406: A V8 engine with a V-angle of 45 degrees. The 8-cylinder versions of the 1945 through 1966 EMD 567 diesel locomotive engine also used a V-angle of 45 degrees. Most V8 engines fitted to road cars use a cross-plane crankshaft since this configuration produces less vibration due to the perfect primary balance and secondary balance. The cross-plane crankshaft has the four crank pins (numbered from
2064-498: A chemistry textbook in which he used the spelling aluminum . Both spellings have coexisted since. Their usage is currently regional: aluminum dominates in the United States and Canada; aluminium is prevalent in the rest of the English-speaking world. In 1812, British scientist Thomas Young wrote an anonymous review of Davy's book, in which he proposed the name aluminium instead of aluminum , which he thought had
2193-528: A common crankshaft and are arranged in a V configuration . The first known V8 was the Antoinette , designed by Léon Levavasseur , and built in 1904 by the French Antoinette company for use in speedboat racing, cars, and later, airplanes. Also in 1904, V8 engines began small-scale production by Renault and Buchet for use in race cars. Most engines use a V-angle (the angle between

It has a great affinity towards oxygen , forming a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver , both in its color and in its great ability to reflect light. It is soft, nonmagnetic , and ductile . It has one stable isotope, Al, which is highly abundant, making aluminium
2451-606: A different 1949 KSC won Best in Class for Kurtis street vehicles at the 2011 Amelia Island Concours d'Elegance. The 2017 Pebble Beach Concours d'Elegance program described the KSC as the first "true American sports car". At the 2019 Amelia Island Concours d'Elegance auction, a 1950 KSC sold for $ 263,200. Aluminium Aluminium (or aluminum in North American English ) is a chemical element ; it has symbol Al and atomic number 13. Aluminium has
2580-462: A mix of imported and local parts. A 4.4 L (269 cu in) version of the Rover V8 engine was produced in Australia for the ill-fated 1973–1975 Leyland P76 sedan. The engine had an overhead valve design and was the only all-aluminum engine made in Australia. The 1958–1965 Hongqi CA72 was a luxury car, of which approximately 200 were built for government officials. It was powered by
2709-480: A modified KSC to 142.515 mph (229.356 km/h) on the Bonneville Salt Flats . In September 1949, that same KSC was featured on the cover of the first issue of Motor Trend . The KSC also likely inspired Harley Earl 's Project Opel at General Motors (GM), which ultimately created the production Chevrolet Corvette . The KSC was additionally described as the first "true American sports car" in

#17327983512792838-465: A more covalent character. The strong affinity of aluminium for oxygen leads to the common occurrence of its oxides in nature. Aluminium is found on Earth primarily in rocks in the crust , where it is the third-most abundant element , after oxygen and silicon , rather than in the mantle , and virtually never as the free metal . It is obtained industrially by mining bauxite , a sedimentary rock rich in aluminium minerals. The discovery of aluminium
2967-441: A probable cause for it being soft with a low melting point and low electrical resistivity . Aluminium metal has an appearance ranging from silvery white to dull gray depending on its surface roughness . Aluminium mirrors are the most reflective of all metal mirrors for near ultraviolet and far infrared light. It is also one of the most reflective for light in the visible spectrum, nearly on par with silver in this respect, and
3096-683: A process termed passivation . Because of its general resistance to corrosion, aluminium is one of the few metals that retains silvery reflectance in finely powdered form, making it an important component of silver-colored paints. Aluminium is not attacked by oxidizing acids because of its passivation. This allows aluminium to be used to store reagents such as nitric acid , concentrated sulfuric acid , and some organic acids. In hot concentrated hydrochloric acid , aluminium reacts with water with evolution of hydrogen, and in aqueous sodium hydroxide or potassium hydroxide at room temperature to form aluminates —protective passivation under these conditions
3225-525: A refractory material, and in ceramics , as well as being the starting material for the electrolytic production of aluminium. Sapphire and ruby are impure corundum contaminated with trace amounts of other metals. The two main oxide-hydroxides, AlO(OH), are boehmite and diaspore . There are three main trihydroxides: bayerite , gibbsite , and nordstrandite , which differ in their crystalline structure ( polymorphs ). Many other intermediate and related structures are also known. Most are produced from ores by
3354-421: A removable hardtop . The KSC measures 51 inches (1,300 mm) in height, 169 inches (4,300 mm) in length, and 68 inches (1,700 mm) in width. Its wheelbase is 100 inches (2,500 mm) and it weighs 2,300 pounds (1,000 kg). The KSC features a distinctive and sturdy front bumper and grille . It also boasts independent front suspension and semi-elliptic rear suspension . The production car
3483-643: A secret program at General Motors (GM) known as Project Opel. Its goal was to create a fiberglass-bodied car using production components, similar to what Kraft had attempted with the KSC. First unveiled at Motorama in 1953 as the EX-122, the resulting GM car eventually entered production as the Chevrolet Corvette . A 1949 KSC won the Motor Trend Classic Award – Editor's Choice at the 2010 Amelia Island Concours d'Elegance , while
3612-478: A single overhead camshaft and was rear-mounted in the vehicles. The company's first V8 road car was the 1973–1974 Dino 308 GT4 mid-engined sports car. The engine is a 90-degree all-aluminum V8 with double overhead camshafts. In 1975, the 2.0 L (122 cu in) engine in the Ferrari 208 GT4 became the smallest production V8 engine ever produced. The model lineage of mid-engined V8 road cars continues to
3741-474: A stable noble gas configuration. Accordingly, the combined first three ionization energies of aluminium are far lower than the fourth ionization energy alone. Such an electron configuration is shared with the other well-characterized members of its group, boron , gallium , indium , and thallium ; it is also expected for nihonium . Aluminium can surrender its three outermost electrons in many chemical reactions (see below ). The electronegativity of aluminium
3870-654: A strict ruleset to follow until the 1972 season, when engines were no longer allowed to be any bigger than 358 cu in (5.9 L) for the purpose of reducing speeds caused by the rapid aerodynamic advancements from 1969 to 1971. In the American Top Fuel class of drag racing, V8 engines displacing 500 cu in (8 L) today produce outputs of over 7,000 kW (10,000 hp). and 10,000 N⋅m (7,400 lb⋅ft). The engines used in Top Fuel and Funny car drag racing are typically based on
3999-513: A top speed of 105 mph (169 km/h), faster than all American production cars at the time. In August 1949, Wally Parks , founder of the National Hot Rod Association (NHRA) and co-founder of Hot Rod magazine , drove a KSC powered by a performance-modified Ford V8 engine to 142.515 mph (229.356 km/h) on the Bonneville Salt Flats . In September 1949, the KSC that was driven by Wally Parks at Bonneville

4128-820: A variety of wet processes using acid and base. Heating the hydroxides leads to formation of corundum. These materials are of central importance to the production of aluminium and are themselves extremely useful. Some mixed oxide phases are also very useful, such as spinel (MgAl 2 O 4 ), Na-β-alumina (NaAl 11 O 17 ), and tricalcium aluminate (Ca 3 Al 2 O 6 , an important mineral phase in Portland cement ). The only stable chalcogenides under normal conditions are aluminium sulfide (Al 2 S 3 ), selenide (Al 2 Se 3 ), and telluride (Al 2 Te 3 ). All three are prepared by direct reaction of their elements at about 1,000 °C (1,800 °F) and quickly hydrolyze completely in water to yield aluminium hydroxide and
4257-575: A way of purifying bauxite to yield alumina, now known as the Bayer process , in 1889. Modern production of aluminium is based on the Bayer and Hall–Héroult processes. As large-scale production caused aluminium prices to drop, the metal became widely used in jewelry, eyeglass frames, optical instruments, tableware, and foil , and other everyday items in the 1890s and early 20th century. Aluminium's ability to form hard yet light alloys with other metals provided
4386-734: Is Al : while it was present along with stable Al in the interstellar medium from which the Solar System formed, having been produced by stellar nucleosynthesis as well, its half-life is only 717,000 years and therefore a detectable amount has not survived since the formation of the planet. However, minute traces of Al are produced from argon in the atmosphere by spallation caused by cosmic ray protons. The ratio of Al to Be has been used for radiodating of geological processes over 10 to 10 year time scales, in particular transport, deposition, sediment storage, burial times, and erosion. Most meteorite scientists believe that
4515-434: Is Al. Al was present in the early Solar System with abundance of 0.005% relative to Al but its half-life of 728,000 years is too short for any original nuclei to survive; Al is therefore extinct . Unlike for Al, hydrogen burning is the primary source of Al, with the nuclide emerging after a nucleus of Mg catches a free proton. However, the trace quantities of Al that do exist are the most common gamma ray emitter in
4644-407: Is paramagnetic and thus essentially unaffected by static magnetic fields. The high electrical conductivity, however, means that it is strongly affected by alternating magnetic fields through the induction of eddy currents . Aluminium combines characteristics of pre- and post-transition metals. Since it has few available electrons for metallic bonding, like its heavier group 13 congeners, it has
4773-483: Is 1.61 (Pauling scale). A free aluminium atom has a radius of 143 pm . With the three outermost electrons removed, the radius shrinks to 39 pm for a 4-coordinated atom or 53.5 pm for a 6-coordinated atom. At standard temperature and pressure , aluminium atoms (when not affected by atoms of other elements) form a face-centered cubic crystal system bound by metallic bonding provided by atoms' outermost electrons; hence aluminium (at these conditions)
4902-548: Is a metal. This crystal system is shared by many other metals, such as lead and copper ; the size of a unit cell of aluminium is comparable to that of those other metals. The system, however, is not shared by the other members of its group: boron has ionization energies too high to allow metallization, thallium has a hexagonal close-packed structure, and gallium and indium have unusual structures that are not close-packed like those of aluminium and thallium. The few electrons that are available for metallic bonding in aluminium are
5031-522: Is almost never found in the elemental state; instead it is found in oxides or silicates. Feldspars , the most common group of minerals in the Earth's crust, are aluminosilicates. Aluminium also occurs in the minerals beryl , cryolite , garnet , spinel , and turquoise . Impurities in Al 2 O 3 , such as chromium and iron , yield the gemstones ruby and sapphire , respectively. Native aluminium metal
5160-405: Is also easily machined and cast . Aluminium is an excellent thermal and electrical conductor , having around 60% the conductivity of copper , both thermal and electrical, while having only 30% of copper's density. Aluminium is capable of superconductivity , with a superconducting critical temperature of 1.2 kelvin and a critical magnetic field of about 100 gauss (10 milliteslas ). It
5289-409: Is considered to be the first V8 engine produced in significant quantities. The 1914 Cadillac L-head V8 engine is considered the first road-going V8 engine to be mass-produced in significant quantities, with 13,000 sold the first year. This engine was built in the United States and was greatly assisted by Cadillac's pioneering use of electric starter motors . The popularity of V8 engines in cars

5418-553: Is extremely rare and can only be found as a minor phase in low oxygen fugacity environments, such as the interiors of certain volcanoes. Native aluminium has been reported in cold seeps in the northeastern continental slope of the South China Sea . It is possible that these deposits resulted from bacterial reduction of tetrahydroxoaluminate Al(OH) 4 . Although aluminium is a common and widespread element, not all aluminium minerals are economically viable sources of
5547-536: Is greatly reduced by aqueous salts, particularly in the presence of dissimilar metals. Aluminium reacts with most nonmetals upon heating, forming compounds such as aluminium nitride (AlN), aluminium sulfide (Al 2 S 3 ), and the aluminium halides (AlX 3 ). It also forms a wide range of intermetallic compounds involving metals from every group on the periodic table. The vast majority of compounds, including all aluminium-containing minerals and all commercially significant aluminium compounds, feature aluminium in
5676-492: Is in fact more basic than that of gallium. Aluminium also bears minor similarities to the metalloid boron in the same group: AlX 3 compounds are valence isoelectronic to BX 3 compounds (they have the same valence electronic structure), and both behave as Lewis acids and readily form adducts . Additionally, one of the main motifs of boron chemistry is regular icosahedral structures, and aluminium forms an important part of many icosahedral quasicrystal alloys, including
5805-409: Is known to metabolize aluminium salts , but this aluminium is well tolerated by plants and animals. Because of the abundance of these salts, the potential for a biological role for them is of interest, and studies are ongoing. Of aluminium isotopes, only Al is stable. This situation is common for elements with an odd atomic number. It is the only primordial aluminium isotope, i.e.
5934-500: Is negligible. Aqua regia also dissolves aluminium. Aluminium is corroded by dissolved chlorides , such as common sodium chloride , which is why household plumbing is never made from aluminium. The oxide layer on aluminium is also destroyed by contact with mercury due to amalgamation or with salts of some electropositive metals. As such, the strongest aluminium alloys are less corrosion-resistant due to galvanic reactions with alloyed copper , and aluminium's corrosion resistance
6063-521: Is not as important. It is a polymer with the formula (AlH 3 ) n , in contrast to the corresponding boron hydride that is a dimer with the formula (BH 3 ) 2 . Aluminium's per-particle abundance in the Solar System is 3.15 ppm (parts per million). It is the twelfth most abundant of all elements and third most abundant among the elements that have odd atomic numbers, after hydrogen and nitrogen. The only stable isotope of aluminium, Al,
6192-416: Is quite soft and lacking in strength. In most applications various aluminium alloys are used instead because of their higher strength and hardness. The yield strength of pure aluminium is 7–11 MPa , while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa. Aluminium is ductile , with a percent elongation of 50-70%, and malleable allowing it to be easily drawn and extruded . It
6321-422: Is surrounded by six fluorine atoms in a distorted octahedral arrangement, with each fluorine atom being shared between the corners of two octahedra. Such {AlF 6 } units also exist in complex fluorides such as cryolite , Na 3 AlF 6 . AlF 3 melts at 1,290 °C (2,354 °F) and is made by reaction of aluminium oxide with hydrogen fluoride gas at 700 °C (1,300 °F). With heavier halides,
6450-547: Is termed amphoterism and is characteristic of weakly basic cations that form insoluble hydroxides and whose hydrated species can also donate their protons. One effect of this is that aluminium salts with weak acids are hydrolyzed in water to the aquated hydroxide and the corresponding nonmetal hydride: for example, aluminium sulfide yields hydrogen sulfide . However, some salts like aluminium carbonate exist in aqueous solution but are unstable as such; and only incomplete hydrolysis takes place for salts with strong acids, such as
6579-416: Is that of the preceding noble gas , whereas those of its heavier congeners gallium , indium , thallium , and nihonium also include a filled d-subshell and in some cases a filled f-subshell. Hence, the inner electrons of aluminium shield the valence electrons almost completely, unlike those of aluminium's heavier congeners. As such, aluminium is the most electropositive metal in its group, and its hydroxide

#17327983512796708-433: Is the eighteenth most abundant nucleus in the universe. It is created almost entirely after fusion of carbon in massive stars that will later become Type II supernovas : this fusion creates Mg, which upon capturing free protons and neutrons, becomes aluminium. Some smaller quantities of Al are created in hydrogen burning shells of evolved stars, where Mg can capture free protons. Essentially all aluminium now in existence

From 1962 through 1965, the top three manufacturers in each season's Constructor's Championship all predominantly used V8 engines in their cars. In 1966, the engine capacity limits were increased to 3.0 L (183 cu in) (or 1.5 litres with a supercharger), and both the 1966 and 1967 Constructor's Championships were won by cars powered by

During this time, the Manufacturers' Championship was won by Cosworth DFV-powered cars every season except 1975, 1976, 1977, and 1979, which 12-cylinder Ferraris won. After a long period of dominance, the Cosworth DFV was eventually outpaced by turbocharged straight-four and V6 engines. The next period of significant V8 usage in Formula One

Aluminium trichloride has major industrial uses involving this reaction, such as in the manufacture of anthraquinones and styrene ; it is also often used as the precursor for many other aluminium compounds and as a reagent for converting nonmetal fluorides into the corresponding chlorides (a transhalogenation reaction ). Aluminium forms one stable oxide with

Overall, the Earth is about 1.59% aluminium by mass (seventh in abundance by mass). Aluminium occurs in greater proportion in the Earth's crust than in the universe at large. This is because aluminium easily forms the oxide and becomes bound into rocks and stays in the Earth's crust , while less reactive metals sink to

From the gas dynamics aspect, the flat-plane crankshaft allows for even exhaust gas pulses to be achieved with a simple exhaust system. The design was popularized in motor racing by the 1961–1965 Coventry Climax FWMV Formula One engine, and the 1967–1985 Cosworth DFV engine was highly successful in Formula One. Several production sports cars have used flat-plane V8 engines, such as every Ferrari V8 model (from
8772-653: The 1939 Tatra 81 to the present day Tatra 815 . French manufacturers were pioneering in their use of V8 engines in the early 1900s with the 1904 Antoinette aircraft engine (the first known V8 engine) and the 1910 De Dion-Bouton . However, there were few French automotive V8 engines in the following decades, with manufacturers such as Delage , Delahaye , Talbot-Lago , Bugatti , and Hotchkiss using six-cylinder or straight-eight engines instead. From 1935 until 1954, Matford (Ford's French subsidiary, later renamed to ' Ford SAF ') produced cars with V8 engines, closely based on contemporary American Ford models. Simca purchased
8901-704: The 1973 Ferrari 308 GT4 to the 2019–present Ferrari F8 Tributo ), the Lotus Esprit V8 , the Porsche 918 Spyder , and the McLaren MP4-12C . The first V8 engine used in a road-going car was the 1905 Rolls-Royce built in the United Kingdom. This model was initially equipped with a 3.5 L (214 cu in) V8 engine. However, only three cars were made before Rolls-Royce reverted to using straight-six engines for their cars. In 1907,
9030-577: The 2017 Pebble Beach Concours d'Elegance program. In the 1920s, Frank Kurtis began his career in the automotive industry working alongside Harley Earl at Don Lee's Cadillac dealership in Los Angeles . By the late 1930s, he was building oval-track midget cars and championship cars for the Indianapolis 500 . During the 1950s, Kurtis's company, Kurtis Kraft , would go on to build cars that would win five Indianapolis 500s. After building
9159-481: The 2019–present Ferrari F8 Tributo . Five-valve-per-cylinder versions were used from 1994 until 2005 in the Ferrari F355 and Ferrari 360 . Turbocharging was introduced on the 1984–1987 Ferrari 288 GTO flagship car, and the range of entry-level mid-engined sports cars switched to turbocharging with the 2015 Ferrari 488 . The Formula One team resumed using V8 engines for the 2006–2013 seasons, beginning with
9288-526: The 5th century BCE. The ancients are known to have used alum as a dyeing mordant and for city defense. After the Crusades , alum, an indispensable good in the European fabric industry, was a subject of international commerce; it was imported to Europe from the eastern Mediterranean until the mid-15th century. The nature of alum remained unknown. Around 1530, Swiss physician Paracelsus suggested alum
9417-505: The 8.2 L (500 cu in) V8 engine used in the 1971–1978 Cadillac Eldorado and BMW's 3.0 L (183 cu in) M60B30 V8 engine found in cars such as the BMW E34 530i. V8 engines intended for motorsport are often small and short-stroke to maximize RPMs and thus power. The Cosworth DFV 3.0 L (183 cu in) is such an engine. Due to its large external dimensions, V8 engines are typically used in cars that use
9546-472: The Al–Zn–Mg class. Aluminium has a high chemical affinity to oxygen, which renders it suitable for use as a reducing agent in the thermite reaction. A fine powder of aluminium reacts explosively on contact with liquid oxygen ; under normal conditions, however, aluminium forms a thin oxide layer (~5 nm at room temperature) that protects the metal from further corrosion by oxygen, water, or dilute acid,
9675-574: The Ford SAF in 1954 and continued to produce various models powered by the Ford Flathead V8 until 1969. After WW2, France imposed very steep tax horsepower charges - the owners of cars with engines above 2 L were financially penalized, so France had a small domestic market for larger-engined cars, such as the V8. Despite this, Facel Vega produced luxury and sports cars powered by Chrysler V8 engines from 1954 through 1964. One of
9804-477: The KSC, with assembly occurring at its plant in Los Angeles. At the same time, it announced the KSC would also be available as a kit car . The base price for the KSC in 1949 was $ 3,495, and with options it could cost up to $ 5,000. At the high end, it was approximately $ 1,000 more expensive than the then-new Jaguar XK120 . During 1949, Kurtis had only sold about 15 to 20 KSCs, by which point he realized that
9933-418: The United States dollar, and alumina prices. The BRIC countries' combined share in primary production and primary consumption grew substantially in the first decade of the 21st century. China is accumulating an especially large share of the world's production thanks to an abundance of resources, cheap energy, and governmental stimuli; it also increased its consumption share from 2% in 1972 to 40% in 2010. In
10062-514: The United States, Western Europe, and Japan, most aluminium was consumed in transportation, engineering, construction, and packaging. In 2021, prices for industrial metals such as aluminium have soared to near-record levels as energy shortages in China drive up costs for electricity. The names aluminium and aluminum are derived from the word alumine , an obsolete term for alumina , the primary naturally occurring oxide of aluminium . Alumine
10191-402: The actual engine displacement. Engines with displacements from 6.0 to 6.6 L (366 to 403 cu in) have been classified as both small-block and big-block, depending on the particular manufacturer's range of engines. V8 engines have been used in many forms of motorsport, from Formula One , IndyCar , NASCAR , DTM and V8 Supercars circuit racing, to Top Fuel drag racing. Among
10320-578: The aluminium atoms have tetrahedral four-coordination and the other half have trigonal bipyramidal five-coordination. Four pnictides – aluminium nitride (AlN), aluminium phosphide (AlP), aluminium arsenide (AlAs), and aluminium antimonide (AlSb) – are known. They are all III-V semiconductors isoelectronic to silicon and germanium , all of which but AlN have the zinc blende structure. All four can be made by high-temperature (and possibly high-pressure) direct reaction of their component elements. Aluminium alloys well with most other metals (with

The world's fastest non-jet-powered (i.e., piston-engine powered) wheeled land vehicle, the Speed Demon, which achieved a speed of 744.072 km/h (462.345 mph) in 2017, is powered by a V8 engine based on the Chevrolet small-block engine design. The first Australian-designed car to use
10578-434: The car was not sustainable financially. In 1950, he sold the KSC's manufacturing rights, along with its blueprints, parts, and tooling, to Earl "Madman" Muntz for $ 200,000. By the time of the sale, only 18 to 36 KSCs had been produced. Production costs were ultimately the demise of the car. In a contemporary review, Tom McCahill of Mechanix Illustrated tested a KSC and reported a 0 to 60 mph time of 11.5 seconds and
10707-436: The characteristic physical properties of a post-transition metal, with longer-than-expected interatomic distances. Furthermore, as Al is a small and highly charged cation, it is strongly polarizing and bonding in aluminium compounds tends towards covalency ; this behavior is similar to that of beryllium (Be ), and the two display an example of a diagonal relationship . The underlying core under aluminium's valence shell
10836-419: The coordination numbers are lower. The other trihalides are dimeric or polymeric with tetrahedral four-coordinate aluminium centers. Aluminium trichloride (AlCl 3 ) has a layered polymeric structure below its melting point of 192.4 °C (378 °F) but transforms on melting to Al 2 Cl 6 dimers. At higher temperatures those increasingly dissociate into trigonal planar AlCl 3 monomers similar to
10965-428: The core. In the Earth's crust, aluminium is the most abundant metallic element (8.23% by mass ) and the third most abundant of all elements (after oxygen and silicon). A large number of silicates in the Earth's crust contain aluminium. In contrast, the Earth's mantle is only 2.38% aluminium by mass. Aluminium also occurs in seawater at a concentration of 2 μg/kg. Because of its strong affinity for oxygen, aluminium
11094-411: The crankshaft can be machined from a flat billet and does not require counterweights so it is lighter. However, it produces more vibration due to a secondary imbalance. Most early V8 road car engines also used a flat-plane crankshaft since this was simpler to design and build than a cross-plane crankshaft. Early flat-plane V8 engines included the 1910 De Dion-Bouton engine, the 1915 Peerless engine, and
11223-497: The energy released by the decay of Al was responsible for the melting and differentiation of some asteroids after their formation 4.55 billion years ago. The remaining isotopes of aluminium, with mass numbers ranging from 21 to 43, all have half-lives well under an hour. Three metastable states are known, all with half-lives under a minute. An aluminium atom has 13 electrons, arranged in an electron configuration of [ Ne ] 3s 3p , with three electrons beyond
11352-478: The exception of most alkali metals and group 13 metals) and over 150 intermetallics with other metals are known. Preparation involves heating fixed metals together in certain proportion, followed by gradual cooling and annealing . Bonding in them is predominantly metallic and the crystal structure primarily depends on efficiency of packing. There are few compounds with lower oxidation states. A few aluminium(I) compounds exist: AlF, AlCl, AlBr, and AlI exist in
11481-520: The fact that its nuclei are much lighter, while difference in the unit cell size does not compensate for this difference. The only lighter metals are the metals of groups 1 and 2 , which apart from beryllium and magnesium are too reactive for structural use (and beryllium is very toxic). Aluminium is not as strong or stiff as steel, but the low density makes up for this in the aerospace industry and for many other applications where light weight and relatively high strength are crucial. Pure aluminium
11610-460: The first German V8 engines was the 1928–1945 Argus As 10 aircraft engine. This engine was air-cooled, used an 'inverted V' design, and was used in several training, surveillance, and communications airplanes. From 1933 until 1940, the Horch 830 luxury cars were powered by V8 engines (sold alongside Horch's larger straight-eight engines). Shortly after, the 1934–1937 Stoewer Greif V8 was powered by
11739-399: The first V8 Formula One cars to compete were the 1952 AFM entry and the 1954 Lancia D50 , with a development of the latter powering Juan Manuel Fangio's 1956 car to victory in the driver's championship. The 1.5 L Formula One era of 1961–1965 included V8 engines from Ferrari, Coventry Climax, British Racing Motors (BRM), and Automobili Turismo e Sport (ATS). The driver's championships for
11868-523: The front) at angles of 0, 90, 270, and 180 degrees, which results in a cross shape for the crankshaft when it is viewed from one end. The rumbling exhaust sound produced by a typical cross-plane V8 engine is partly due to the uneven firing order within each of the two banks of four cylinders. A usual firing order of L-R-L-L-R-L-R-R (or R-L-R-R-L-R-L-L) results in uneven intake and exhaust pulse spacing for each bank. When separate exhaust systems are used for each bank of cylinders, this uneven pulsing results in
11997-730: The gas phase after explosion and in stellar absorption spectra. More thoroughly investigated are compounds of the formula R 4 Al 2 which contain an Al–Al bond and where R is a large organic ligand . A variety of compounds of empirical formula AlR 3 and AlR 1.5 Cl 1.5 exist. The aluminium trialkyls and triaryls are reactive, volatile, and colorless liquids or low-melting solids. They catch fire spontaneously in air and react with water, thus necessitating precautions when handling them. They often form dimers, unlike their boron analogues, but this tendency diminishes for branched-chain alkyls (e.g. Pr , Bu , Me 3 CCH 2 ); for example, triisobutylaluminium exists as an equilibrium mixture of
12126-453: The gaseous phase when the respective trihalide is heated with aluminium, and at cryogenic temperatures. A stable derivative of aluminium monoiodide is the cyclic adduct formed with triethylamine , Al 4 I 4 (NEt 3 ) 4 . Al 2 O and Al 2 S also exist but are very unstable. Very simple aluminium(II) compounds are invoked or observed in the reactions of Al metal with oxidants. For example, aluminium monoxide , AlO, has been detected in
12255-646: The halides, nitrate , and sulfate . For similar reasons, anhydrous aluminium salts cannot be made by heating their "hydrates": hydrated aluminium chloride is in fact not AlCl 3 ·6H 2 O but [Al(H 2 O) 6 ]Cl 3 , and the Al–O bonds are so strong that heating is not sufficient to break them and form Al–Cl bonds instead: All four trihalides are well known. Unlike the structures of the three heavier trihalides, aluminium fluoride (AlF 3 ) features six-coordinate aluminium, which explains its involatility and insolubility as well as high heat of formation . Each aluminium atom
12384-433: The low-pressure polymerization of ethene and propene . There are also some heterocyclic and cluster organoaluminium compounds involving Al–N bonds. The industrially most important aluminium hydride is lithium aluminium hydride (LiAlH 4 ), which is used as a reducing agent in organic chemistry . It can be produced from lithium hydride and aluminium trichloride . The simplest hydride, aluminium hydride or alane,
12513-529: The metal remained rare; its cost exceeded that of gold. The first industrial production of aluminium was established in 1856 by French chemist Henri Etienne Sainte-Claire Deville and companions. Deville had discovered that aluminium trichloride could be reduced by sodium, which was more convenient and less expensive than potassium, which Wöhler had used. Even then, aluminium was still not of great purity and produced aluminium differed in properties by sample. Because of its electricity-conducting capacity, aluminium
12642-655: The metal to be isolated from alum was alumium , which Davy suggested in an 1808 article on his electrochemical research, published in Philosophical Transactions of the Royal Society . It appeared that the name was created from the English word alum and the Latin suffix -ium ; but it was customary then to give elements names originating in Latin, so this name was not adopted universally. This name
12771-465: The metal with many uses at the time. During World War I , major governments demanded large shipments of aluminium for light strong airframes; during World War II , demand by major governments for aviation was even higher. By the mid-20th century, aluminium had become a part of everyday life and an essential component of housewares. In 1954, production of aluminium surpassed that of copper , historically second in production only to iron, making it
12900-434: The metal. Almost all metallic aluminium is produced from the ore bauxite (AlO x (OH) 3–2 x ). Bauxite occurs as a weathering product of low iron and silica bedrock in tropical climatic conditions. In 2017, most bauxite was mined in Australia, China, Guinea, and India. The history of aluminium has been shaped by usage of alum . The first written record of alum, made by Greek historian Herodotus , dates back to
13029-485: The monomer and dimer. These dimers, such as trimethylaluminium (Al 2 Me 6 ), usually feature tetrahedral Al centers formed by dimerization with some alkyl group bridging between both aluminium atoms. They are hard acids and react readily with ligands, forming adducts. In industry, they are mostly used in alkene insertion reactions, as discovered by Karl Ziegler , most importantly in "growth reactions" that form long-chain unbranched primary alkenes and alcohols, and in
13158-506: The most produced non-ferrous metal . During the mid-20th century, aluminium emerged as a civil engineering material, with building applications in both basic construction and interior finish work, and increasingly being used in military engineering, for both airplanes and land armor vehicle engines. Earth's first artificial satellite , launched in 1957, consisted of two separate aluminium semi-spheres joined and all subsequent space vehicles have used aluminium to some extent. The aluminium can
13287-614: The next decade, the -um spelling dominated American usage. In 1925, the American Chemical Society adopted this spelling. The International Union of Pure and Applied Chemistry (IUPAC) adopted aluminium as the standard international name for the element in 1990. In 1993, they recognized aluminum as an acceptable variant; the most recent 2005 edition of the IUPAC nomenclature of inorganic chemistry also acknowledges this spelling. IUPAC official publications use
13416-507: The only one that has existed on Earth in its current form since the formation of the planet. It is therefore a mononuclidic element and its standard atomic weight is virtually the same as that of the isotope. This makes aluminium very useful in nuclear magnetic resonance (NMR), as its single stable isotope has a high NMR sensitivity. The standard atomic weight of aluminium is low in comparison with many other metals. All other isotopes of aluminium are radioactive . The most stable of these
13545-407: The oxidation state 3+. The coordination number of such compounds varies, but generally Al is either six- or four-coordinate. Almost all compounds of aluminium(III) are colorless. In aqueous solution, Al exists as the hexaaqua cation [Al(H 2 O) 6 ] , which has an approximate K a of 10 . Such solutions are acidic as this cation can act as a proton donor and progressively hydrolyze until
13674-460: The patents he filed between 1886 and 1903. It is unknown whether this spelling was introduced by mistake or intentionally, but Hall preferred aluminum since its introduction because it resembled platinum , the name of a prestigious metal. By 1890, both spellings had been common in the United States, the -ium spelling being slightly more common; by 1895, the situation had reversed; by 1900, aluminum had become twice as common as aluminium ; in
13803-423: The respective hydrogen chalcogenide . As aluminium is a small atom relative to these chalcogens, these have four-coordinate tetrahedral aluminium with various polymorphs having structures related to wurtzite , with two-thirds of the possible metal sites occupied either in an orderly (α) or random (β) fashion; the sulfide also has a γ form related to γ-alumina, and an unusual high-temperature hexagonal form where half
13932-693: The rumbling sound typically associated with V8 engines. However, racing engines seek to avoid these uneven exhaust pressure pulses to maximize the power output. The 1960s cross-plane V8 racing engines used long primary exhaust pipes (such as the Ford GT40 endurance racing car) or located the exhaust ports on the inside of the V-angle (such as the Lotus 38 IndyCar) to link the exhaust systems from each bank and provide even exhaust gas pulses),. A flat-plane crankshaft configuration provides two benefits. Mechanically,
14061-485: The scale of the economies. However, the need to exploit lower-grade poorer quality deposits and the use of fast increasing input costs (above all, energy) increased the net cost of aluminium; the real price began to grow in the 1970s with the rise of energy cost. Production moved from the industrialized countries to countries where production was cheaper. Production costs in the late 20th century changed because of advances in technology, lower energy prices, exchange rates of
14190-408: The structure of BCl 3 . Aluminium tribromide and aluminium triiodide form Al 2 X 6 dimers in all three phases and hence do not show such significant changes of properties upon phase change. These materials are prepared by treating aluminium with the halogen. The aluminium trihalides form many addition compounds or complexes; their Lewis acidic nature makes them useful as catalysts for
14319-457: The then-new Jaguar XK120 . After Frank Kurtis realized that the car was not sustainable financially, largely due to production costs , he sold the KSC's manufacturing rights, along with its blueprints, parts, and tooling, to Earl "Madman" Muntz for $ 200,000 in 1950. By that time, only 18 to 36 KSCs had been produced. In August 1949, Wally Parks , founder of the National Hot Rod Association (NHRA) and co-founder of Hot Rod magazine , drove
14448-421: The two banks of cylinders) of 90 degrees. This angle results in good engine balance , which results in low vibrations. However, the downside is the greater width of the engine compared to those that use a smaller V-angle. V8 engines with a 60-degree V-angle were used in the 1996–1999 Ford Taurus SHO , the 2005–2011 Volvo XC90 , and the 2006–2009 Volvo S80 . The Ford engine used a 60-degree V-angle because it
14577-536: The two therefore look similar. Aluminium is also good at reflecting solar radiation , although prolonged exposure to sunlight in air adds wear to the surface of the metal; this may be prevented if aluminium is anodized , which adds a protective layer of oxide on the surface. The density of aluminium is 2.70 g/cm , about 1/3 that of steel, much lower than other commonly encountered metals, making aluminium parts easily identifiable through their lightness. Aluminium's low density compared to most other metals arises from
14706-461: Was a salt of an earth of alum. In 1595, German doctor and chemist Andreas Libavius experimentally confirmed this. In 1722, German chemist Friedrich Hoffmann announced his belief that the base of alum was a distinct earth. In 1754, German chemist Andreas Sigismund Marggraf synthesized alumina by boiling clay in sulfuric acid and subsequently adding potash . Attempts to produce aluminium date back to 1760. The first successful attempt, however,
14835-677: Was also used in touring car racing and formed the basis of the Repco-Holden engine used in Formula 5000 racing. In 1999, the Holden V8 engine began to be replaced by the imported General Motors LS1 V8 engine. In 1971, Ford Australia began local production of the Ford 'Cleveland' V8 , an overhead valve cast-iron engine. The engine was produced in displacements of 4.9 L (302 cu in) and 5.8 L (351 cu in) for use in
14964-531: Was announced in 1825 by Danish physicist Hans Christian Ørsted . The first industrial production of aluminium was initiated by French chemist Henri Étienne Sainte-Claire Deville in 1856. Aluminium became much more available to the public with the Hall–Héroult process developed independently by French engineer Paul Héroult and American engineer Charles Martin Hall in 1886, and the mass production of aluminium led to its extensive use in industry and everyday life. In
15093-549: Was based on a V6 engine with a 60-degree V-angle. Both the Ford and Volvo engines were used in transverse engine chassis, which were designed for a front-wheel-drive layout (with an on-demand all-wheel drive system in the case of the Volvos ). To reduce the vibrations caused by the unbalanced 60-degree V-angle, the Volvo engines used a balance shaft and offset split crankpins . The Rolls-Royce Meteorite tank engine also used
15222-494: Was borrowed from French, which in turn derived it from alumen , the classical Latin name for alum , the mineral from which it was collected. The Latin word alumen stems from the Proto-Indo-European root *alu- meaning "bitter" or "beer". British chemist Humphry Davy , who performed a number of experiments aimed to isolate the metal, is credited as the person who named the element. The first name proposed for
15351-408: Was built with the chassis , V8 engine , suspension , and brakes from a 1949 Ford. The choice of engines offered by Kraft ranged from 82 hp (61 kW) to 160 hp (120 kW). The production KSC's body panels were mostly made of aluminum supported by a steel frame , although some of its panels were made from fiberglass or steel. In May 1949, Kurtis Kraft announced limited production of
15480-422: Was completed in 1824 by Danish physicist and chemist Hans Christian Ørsted . He reacted anhydrous aluminium chloride with potassium amalgam , yielding a lump of metal looking similar to tin. He presented his results and demonstrated a sample of the new metal in 1825. In 1827, German chemist Friedrich Wöhler repeated Ørsted's experiments but did not identify any aluminium. (The reason for this inconsistency
15609-496: Was criticized by contemporary chemists from France, Germany, and Sweden, who insisted the metal should be named for the oxide, alumina, from which it would be isolated. The English name alum does not come directly from Latin, whereas alumine / alumina obviously comes from the Latin word alumen (upon declension , alumen changes to alumin- ). One example was Essai sur la Nomenclature chimique (July 1811), written in French by
15738-681: Was featured on the cover of the first issue of Motor Trend . Publisher Robert E. "Pete" Petersen , who was partially inspired by Frank Kurtis to start the magazine, may have chosen the KSC for the first cover of Motor Trend in part due to his relationship with Kurtis. That car, the first production KSC and the third built overall (serial number KB003), was purchased by Motor Trend in 2019 and put on display at its headquarters in El Segundo, California . That year, 70 years after reviewing it for its first issue, Motor Trend decided to test KB003, finding that it weighed 2,835 pounds (1,286 kg), had
15867-575: Was first used on the Mercedes-Benz M113 engine in 2002 and turbocharging was first used on non-commercial diesel V8 engines in 1999 with the OM628 and on petrol engines with the M278 engine in 2010. Porsche's first road car to use a V8 engine was the 1978 Porsche 928 coupe. Its first to use a V8 diesel engine was the second-generation Cayenne S Diesel in 2014. Audi's first road car to use
15996-496: Was from 2006 to 2013 , when the rules mandated use of 2.4 L (146 cu in) naturally-aspirated V8 engines, with regular power outputs between 730 and 810 hp (in order to reduce the power outputs being achieved by the previous 3.0 litre V10 engines). These were replaced by 1.6 litre turbocharged V6 engines for the 2014 and later seasons. V8 engines have dominated American premier stock car racing NASCAR series since its inaugural 1949 season . However, there wasn't
16125-418: Was invented in 1956 and employed as a storage for drinks in 1958. Throughout the 20th century, the production of aluminium rose rapidly: while the world production of aluminium in 1900 was 6,800 metric tons, the annual production first exceeded 100,000 metric tons in 1916; 1,000,000 tons in 1941; 10,000,000 tons in 1971. In the 1970s, the increased demand for aluminium made it an exchange commodity; it entered
16254-433: Was only discovered in 1921.) He conducted a similar experiment in the same year by mixing anhydrous aluminium chloride with potassium and produced a powder of aluminium. In 1845, he was able to produce small pieces of the metal and described some physical properties of this metal. For many years thereafter, Wöhler was credited as the discoverer of aluminium. As Wöhler's method could not yield great quantities of aluminium,
16383-466: Was significantly increased following the 1932 introduction of the Ford Flathead V8 . By the early 21st century, the use of V8 engines in passenger vehicles declined as automobile manufacturers opted for more fuel efficient , lower capacity engines, or hybrid and electric drivetrains . The displacement of modern V8 engines is typically from 3.5 to 6.4 L (214 to 391 cu in). However, larger and smaller examples have been produced, such as
16512-496: Was the 2008–present BMW N63 engine. Their first eight-cylinder engine since passenger car and motorsport straight-eight engine production stopped in 1944 and 1955 respectively, Mercedes-Benz began production of the Mercedes-Benz M100 petrol V8 engine in 1963 and has continued production of V8 engines to the present day. The M100 had a single overhead camshaft, a cast-iron block, and an aluminium head. Supercharging
16641-580: Was used as the cap of the Washington Monument , completed in 1885. The tallest building in the world at the time, the non-corroding metal cap was intended to serve as a lightning rod peak. The first industrial large-scale production method was independently developed in 1886 by French engineer Paul Héroult and American engineer Charles Martin Hall ; it is now known as the Hall–Héroult process . The Hall–Héroult process converts alumina into metal. Austrian chemist Carl Joseph Bayer discovered
