Leaded Gunmetal LG4

Leaded bronzes and gunmetals offer better machining characteristics than other bronzes while maintaining a good balance of corrosion resistance and strength. Leaded gunmetal LG4 is a leaded gunmetal bronze conforming to the requirements of B.S. 1400 – 1985 alloy LG4. It has excellent machining properties, medium strength, good pressure tightness and is not subject to dezincification. It also has good corrosion resistance to seawater and brine, making it suitable for pump and valve components. LG4 is suitable for bearings having light loads and low to medium speeds with adequate lubrication. LG4 is preferred to LG2 where pump impeller peripheral velocities are higher (up to 25m/sec).
