High Quality Content by WIKIPEDIA articles! Gunmetal, also known as red brass in the United States, is a type of bronze – an alloy of copper, tin, and zinc. Originally used chiefly for making guns, gunmetal was superseded by steel. Gunmetal is resistant to corrosion from steam and salt water. 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. U.S. Government bronze specification G is a gunmetal composed of 88% copper, 10% tin, and 2% zinc. U.S. Government bronze specification H is composed of 83% copper, 14% tin, 3% zinc, and 0.8% phosphorus. Red brass also contains approximately 5% lead.
