Gun Metal

Gunmetal, also called G Metal, variety of bronze, formerly used for ordnance. Modern admiralty gunmetal is composed of 88 percent copper, 10 percent tin, and 2 percent zinc and is used for gears and bearings that are to be subjected to heavy loads and low speeds. It withstands atmospheric, steam, and seawater corrosion and is suitable for valves, pump parts, and steam fittings.

Gunmetal is a copper-tin cast alloy to which zinc has been added. Lead can also be added to improve machining and gliding properties. Thanks to its special properties, gunmetal plays a special role among the tin bronzes. It is corrosion resistant and also resistant to stress corrosion cracking and denitrification.

 

Gunmetal is used in the building industry for valves, screwed, soldered and pressed fittings for sanitary and heating engineering and complies with the hygiene requirements of DIN 50930-6. Particularly in sanitary installations, gunmetal is ideal for shut-off, safety and control valves, as fittings material for pipe system components or as constructional material in water, filter and purification technology. gunmetal is ideal for universal use and can be combined as required with all known installation materials (copper, stainless steel, galvanised steel and plastic). gunmetal with the correct composition can be used without restrictions in drinking water applications. Thanks to its outstanding gliding and emergency running properties, gunmetal is also frequently used as a material for plain bearings in drive technology. The copper-tin-zinc group of cast alloys (gunmetal) is in quantitative terms the largest application group of tin bronzes.
