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]
Copper is also considered a base metal because it oxidizes relatively easily, although it does not react with HCl. In mining and economics, the term base metals refers to industrial non-ferrous metals excluding precious metals. These include copper, lead, nickel and zinc. [3]
Non-ferrous metals and alloys lack appreciable amounts of iron. Brittle elemental metal While nearly all elemental metals are malleable or ductile, a few—beryllium, chromium, manganese, gallium, and bismuth—are brittle. [ 40 ]
There are two main categories of metals: ferrous and non-ferrous. Metals that contain iron in them are known as ferrous. Metals without iron are non-ferrous. Common non-ferrous metals are copper, brass, aluminum, zinc, magnesium, tin, nickel, and lead. Usable coins can be deposited in banks. Damaged US coins can be redeemed for money via the ...
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 ...

The adjective ferrous or the prefix ferro-is often used to specify such compounds, as in ferrous chloride for iron(II) chloride (FeCl 2). The adjective ferric is used instead for iron(III) salts, containing the cation Fe 3+. The word ferrous is derived from the Latin word ferrum, meaning "iron".
