GUN METAL SCRAP

Gunmetal is a type of bronze an alloy of copper, tin and zinc and other metal in minimal proportion. Proportions vary but 88% copper, 8–10% tin, and 2–4% zinc is an approximation. Gunmetal, which casts and machines well is resistant to corrosion from steam and salt water, is used to make steam and hydraulic castings, valves, gears, statues, and various small objects. We deal with gun metal scrap of different grades as per the customer’s requirements.
