In metallurgy, non-ferrous metals are metals or alloys that do not contain iron (allotropes of iron, ferrite, and so on) in appreciable amounts.. Generally more costly than ferrous metals, non-ferrous metals are used because of desirable properties such as low weight (e.g. aluminium), higher conductivity (e.g. copper), [1] non-magnetic properties or resistance to corrosion (e.g. zinc). [2]
An alloy is a mixture of chemical elements, which forms an impure substance (admixture) that retains the characteristics of a metal. An alloy is distinct from an impure metal in that, with an alloy, the added elements are well controlled to produce desirable properties, while impure metals such as wrought iron are less controlled, but are often ...
Heusler alloy, a range of ferromagnetic alloys (66% copper, cobalt, iron, manganese, nickel or palladium) High-entropy alloys; Intermetallic compounds; List of brazing alloys; Pot metal; inexpensive casting metal of non-specific composition
Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter, and tin-based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used. The casting equipment and the metal dies represent large capital costs and this tends to limit the process to high-volume ...
Semi-solid metal casting (SSM) is a near net shape variant of die casting. [1] The process is used today with non-ferrous metals, such as aluminium , copper , [ 2 ] and magnesium . It can work with higher temperature alloys that lack suitable die materials.
Non-ferrous extractive metallurgy is one of the two branches of extractive metallurgy which pertains to the processes of reducing valuable, non-iron metals from ores or raw material. [ 1 ] [ 2 ] [ 3 ] Metals like zinc , copper , lead , aluminium as well as rare and noble metals are of particular interest in this field, [ 1 ] while the more ...
