Copper Alloy LG2 Gunmetal Bushings
Copper Alloy LG2 Gunmetal Bushings
LG2 has excellent machining properties, medium strength, good pressure tightness and is not
subject to dezincification (Category I alloy), and has reasonable corrosion resistance to seawater
and brine, making it suitable for pump and valve components.
LG2 is suitable for bearings having light loads and low to medium speeds with adequate
lubrication, and for very light duty gears when loading is negligible
Copper LG2 is a base alloy CuSn noted for its excellent properties of toughness, toughness, wear resistance, corrosion and elasticity. They need to have good lubrication, which allows them to work with high specific loads. Tin copper alloy also known as red bronze or leaded gunmetal.
The closest international standards are the BS 1400 LG2, the ASTM B505 C83600 and the CuSn5ZnPb (Rg5).
