Gunmetal is also known as Red brass. It is a type of bronze – an alloy of copper (88%), tin (10%), and zinc (2%). Originally used chiefly for making guns, gunmetal was eventually superseded by steel. Gunmetal casts and machines well and is resistant to corrosion from steam and salt water and is used to make steam and hydraulic castings, valves, and gears, and also statues and various small objects, e.g. buttons. It has a tensile strength of 221 to 310 MPa, a specific gravity of 8.7, a density 8,719 kg/m3, and a Brinell Hardness of 65 to 74.

Gunmetal can also mean steel treated to simulate gunmetal bronze. Bushings made of this metal are used in machinery.
