Full alloy description:

A.W. Fraser Alloy LG2 Low Lead is a general purpose leaded gunmetal conforming to the requirements of B.S. 1400 - 1985 alloy LG2.

It has a modified lead range of 4.0 to 4.5 making it suitable for use with potable water.

LG2 Low Lead 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 Low Lead 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 A.W. Fraser alloy LG2 Low Lead is strictly controlled as are the casting conditions.

LG2 Low Lead products are manufactured using the latest continuous and centrifugal casting technology.
Machinability Rating: 85
SAE Grade: 40/J462
