Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals, such as phosphorus, or metalloids, such as arsenic or silicon.
Ferrous metallurgy is the metallurgy of iron and its alloys. The earliest surviving prehistoric iron artifacts, from the 4th millennium BC in Egypt , [ 1 ] were made from meteoritic iron-nickel . [ 2 ]
A number of more exotic metals have been used to make demonstration or fantasy coins which have not been used to make monetized coins for a nation-state. Some of these elements would make excellent coins in theory (e.g. zirconium). More expensive metals that are intrinsically valuable as commodities are less practical as coinage due to their ...
The metals of antiquity are the seven metals which humans had identified and found use for in prehistoric times in Africa, Europe and throughout Asia: [1] gold, silver, copper, tin, lead, iron, and mercury. Zinc, arsenic, and antimony were also known during antiquity, but they were not recognised as distinct metals until later.

Brass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic and chemical properties, [1] but copper typically has the larger proportion, generally 66% copper and 34% zinc.
The Chalcolithic-period Nahal Mishmar hoard in the Judean Desert west of the Dead Sea contains a number of arsenical bronze (4–12% arsenic) and perhaps arsenical copper artifacts made using the lost-wax process, the earliest known use of this complex technique. "Carbon-14 dating of the reed mat in which the objects were wrapped suggests that ...
