Gilding metal is a copper alloy, a brass, comprising 95% copper and 5% zinc.[1]

Gilding metal is used for various purposes, including the jackets of bullets, driving bands on some artillery shells,[2] 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).[3] It should be cooled slowly afterwards, to reduce risk of cracking.[4]
