Gunmetal, also known as red brass in the United States, is the most durable of all metals for the plumbing industry and commercial water pipe applications.. Originally used chiefly for making guns, it was eventually superseded in this department by steel. Gunmetal, which casts and machines well and is resistant to corrosion from steam and salt water, is used to make steam and hydraulic castings, valves, gears, statues and various small objects, such as buttons.
