Excellent machinability, medium strength, good pressure tightness; not subject to dezincification.
Full alloy description:
A. W. Fraser Alloy LG2 is a general purpose leaded gunmetal conforming to the requirements of BS 1400 - 1985 alloy LG2. (BS EN 1982 CuSn5Zn5Pb5).
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.
The composition of AW Fraser alloy LG2 is strictly controlled as are the casting conditions.
LG2 products are manufactured using the latest continuous and centrifugal casting technology.
Machinability Rating: 85
SAE Grade: 40/J462
