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.
