Gilding metal

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

Gilding metal is used for various purposes, including the jackets of bullets, driving bands on some artillery shells, as well as enameled badges and other jewellery. The sheet is widely used for craft metalworking by hammer working. 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). It should be cooled slowly afterwards, to reduce risk of cracking.
