Gilding metal

Gilding metal is a copper alloy, a brass, comprising 95% copper and 5% zinc.[1] British Army Dress Regulations define gilding metal as '8 parts copper to 1 of zinc'.[2]

Gilding metal is used for various purposes, including the jackets of bullets, driving bands on some artillery shells,[3] as well as enameled badges and other jewellery. The sheet is widely used for craft metalworking by hammer working.[1] It is also used particularly as a lower-cost training material for silversmiths.

Gilding metal may be annealed by heating to between 800–1,450 °F (427–788 °C).[4] It should be cooled slowly afterwards, to reduce risk of cracking.[5]
