Gunmetal (Red Brass)
Gunmetal, also known as red brass in the United States, is a type of bronze alloy containing copper, tin, and zinc. Proportions vary but 88% copper, 8–10% tin, and 2–4% zinc is an approximation. Originally used for making guns, it has been replaced by steel.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. It has a tensile strength of 221 to 310 MPa, a specific gravity of 8.7, a Brinell hardness of 65 to 74. Gunmetal has a melting point of around 1,000 degrees Celsius.
What is gunmetal made of?
Also called G Metal, a variety of bronze, formerly used for ordnance. Modern admiralty gunmetal is composed of 88 per cent copper, 10 per cent tin, and 2 per cent zinc. Used for gears and bearings that are subject to heavy loads and low speeds.

What are gunmetals used for?
Gunmetals have been used for at least 2,000 years. Popular because of ease of casting, good strength and corrosion resistance. Early uses included brooches, mirror cases, church doors, fonts and statues. Cannon’s in medieval times led to the term ‘gun metal’. This term is now obsolete with the manufacture of steel ordnance.
Gunmetals are noted for the manufacture of intricate castings. These castings need to be pressure tight such as valves, pipe fittings and pumps. Gun metal is used for bearings where loads and speeds are moderate.
