Bhuwal Steel & Metals

Gun metal is a type of bronze – an alloy of copper, tin, and zinc. Originally used chiefly for making guns, gunmetal was superseded by steel. It is called red brass in America. Gunmetal is resistant to corrosion from steam and salt water, and is thus suitable for valves, pump parts and steam fittings. Gun Metal Products 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.
