Gun metal alloy is a copper-tin cast alloy to which zinc is added. Lead can also be added to improve machining and gliding properties. Due to its properties, gun metal alloy plays a special role among the tin bronzes. It is corrosion resistant and also resistant to stress corrosion cracking and dezincification.
Gunmetal is used in the building industry for valves, screwed, soldered and pressed fittings for sanitary and heating engineering. 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.
