The design and manufacture of a metal component involves a multitude of decision points and will be influenced by considerations such as structural performance, weight, lead time, cost and aesthetics. It is understandable, therefore, that thoughts about how precisely that component is going to be manufactured are often left until the design is at a fairly … Read more
LEADED GUNMETAL LG4
(BS 1400 1985 LG4)
Leaded Bronzes and Gunmetals offer better machining characteristics than other Bronzes while maintaining a good balance of corrosion resistance and strength. 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).
