Gunmetal is known as a copper-tin cast alloy, with zinc or lead additions. With a wide range of special properties, gunmetal is the most used form of tin bronzes. It has corrosion resistance properties, resistance to stress corrosion cracking and dezincification. This metal has been used in building valves, screwed/soldered/pressed fittings and more in the sanitary and heating industry. With correct composition, the gunmetal is also used in water filter and purification installations. Due to gliding and emergency running properties, the metal is also used frequently in drive technology, especially plain bearings. With suitable properties, the gunmetal is a standardised valve and plumbing material in a wide range of industries. At JJ Scrap Metals, we specialise in collection and transportation of gunmetal scrap right from your doorstep – at highly competitive prices!
Gunmetal is also known as G-metal and is primarily composed of 88% copper, 10% tin, and 2% zinc. The common gunmetal scrap in the modern times, includes gears and bearings which are used in heavy loads-low speed applications. As gunmetal can withstand corrosion (atmospheric, steam or seawater), it is highly used in steam fittings, valves and pump parts.
