An aluminium alloy ( UK / IUPAC) or aluminum alloy ( NA; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are ...
Aluminium is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.
Apr 19, 2024 · Aluminum, chemical element, a lightweight silvery white metal of Group 13 of the periodic table. Aluminum is the most abundant metallic element in Earth’s crust and the most widely used nonferrous metal. Aluminum never occurs in the metallic form in nature.
Dec 3, 2007 · Today aluminum is a critical component of modern life, found in airplanes, automobiles, soft drink cans, construction materials, cooking equipment, guardrails, and countless other products.
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.
Aluminium or aluminum ( 13 Al) has 22 known isotopes from 22 Al to 43 Al and 4 known isomers. Only 27 Al ( stable isotope) and 26 Al ( radioactive isotope, t 1/2 = 7.2 × 105 y) occur naturally, however 27 Al comprises nearly all natural aluminium.
aluminum, Metallic chemical element, chemical symbol Al, atomic number 13. A lightweight, silvery white metal, it is so reactive chemically that it always occurs in compounds. It is the most abundant metallic element in Earth’s crust, chiefly in bauxite (its principal ore), feldspar s, mica s, clay minerals, and laterite.
