This is a list of primary aluminium smelters in the world. Primary production is the process by which alumina is smelted to pure aluminum. [1] Secondary production is the process of recycling aluminum scrap into aluminum that can be used again. [2] Capacity here refers to metric tonnes of output aluminum. The list is incomplete and missing some ...
Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al 3+ is small and highly charged; as such, it has more polarizing power, and bonds formed by aluminium have a more covalent character.
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 further ...
Existing home sales, which make up the vast majority of the market, slumped 2.5% in August from the prior month to a seasonally adjusted annual rate of 3.86 million, the National Association of ...
Electrical properties. Volume resistivity (ρ) 32.5–39.2 nOhm·m. 6061 aluminium alloy (Unified Numbering System (UNS) designation A96061) is a precipitation-hardened aluminium alloy, containing magnesium and silicon as its major alloying elements. Originally called "Alloy 61S", it was developed in 1935. [2]
7075 aluminium alloy. 7075 aluminium alloy (AA7075) is an aluminium alloy with zinc as the primary alloying element. It has excellent mechanical properties and exhibits good ductility, high strength, toughness, and good resistance to fatigue. It is more susceptible to embrittlement than many other aluminium alloys because of microsegregation ...
