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).

A battle axe from the Middle Bronze Age (MB) found in Tel Rumeida, West Bank. Nonferrous archaeometallurgy in the southern Levant is the archaeological study of non-iron-related metal technology in the region of the Southern Levant during the Chalcolithic period and Bronze Age from approximately 4500BC to 1000BC.
The specific study of the non-ferrous metals used in past. Gold, silver and copper were the first to be used by ancient humans. Gold and copper are both found in their 'native' state in nature, and were thus the first to be exploited as they did not need to be smelted from their ores. They could be hammered into sheets or decorative shapes.
The mobilisation of non-ferrous metals was an event in Second World War France, starting in 1941. During it Nazi Germany requisitioned a large amount of non-ferrous metals for its armament factories, including tin, lead, nickel and copper. [1] With the collaboration of the Vichy regime and under the cover-story of supporting French agriculture ...
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 ...
Metallurgy derives from the Ancient Greek μεταλλουργός, metallourgós, "worker in metal", from μέταλλον, métallon, "mine, metal" + ἔργον, érgon, "work" The word was originally an alchemist's term for the extraction of metals from minerals, the ending -urgy signifying a process, especially manufacturing: it was discussed in this sense in the 1797 Encyclopædia ...

World production of the metal grew from 6,800 metric tons in 1900 to 2,810,000 metric tons in 1954, when aluminium became the most produced non-ferrous metal, surpassing copper. In the second half of the 20th century, aluminium gained usage in transportation and packaging.
