Copper Alloys, Phosphor & Leaded BronzeCC492K (LG4) Bar
Leaded tin bronze alloy.
LG4 is a leaded gunmetal bronze with excellent machinability and bearing properties, good corrosion resistance and moderate strength. This alloy has a higher strength than CC490K and CC491K from the additional tin giving better wear resistance.
Leaded bronzes and gunmetals offer better machining characteristics than that of the other bronzes whilst maintaining a good balance of corrosion resistance and strength. Available in cast form only, Righton Blackburns is able to offer material supplied in many internationally recognised standards for use in applications such as bushes and bearings.
