Red Brass

Red brass is both an American term for the copper-zinc-tin alloy known as Gunmetal, and an alloy which is considered both a brass and a bronze. It typically contains 85% copper, 5% tin, 5% lead, and 5% zinc. Red brass is also an alternative name for copper alloy C23000, which is composed of 14-16% zinc, 0.05% iron and lead, and the remainder copper. It may also refer to Ounce Metal, another copper-zinc-tin alloy.
