Gunmetal (Red Brass)
Gunmetal, also known as red brass in the United States, is a type of bronze alloy containing copper, tin, and zinc, measurements vary containing 8–10% tin, 2–4% zinc and 88% copper approximately. Originally used for making guns, it has been replaced by steel. Gunmetal casts and machines well and is resistant to corrosion from steam and saltwater. Used to make steam and hydraulic castings, valves, gears, statues and various objects. Gunmetal has a specific gravity of 8.7, a tensile strength of 221 to 310 MPa and a Brinell hardness of 65 to 74. Gunmetal has a melting point of around 1,000 degrees Celsius.
