Gunmetal is a kind of bronze, an alloy of copper, tin, and some zinc, originally used chiefly for making guns, but later superseded by steel. It is also called red brass in America.
Gunmetals produced for different purposes vary slightly in composition. In some cases, the alloy may be composed only from copper and tin, or from copper, tin, and lead. It has many uses in industry, and is used for statues and various small objects, e.g. buttons.
