Leaded tin bronze with excellent machinability, medium strength and good corrosion resistance. Will withstand mild acids as found in mine water.
Full alloy description:
A. W. Fraser Alloy LB2 is a leaded tin bronze conforming to the requirements of B.S. 1400 - 1985 alloy LB2.
LB2 has excellent machining properties, medium strength and good corrosion resistance and will withstand mild acids as found in mine water.
Bearings manufactured from LB2 have excellent wear resistance under conditions of high speed, heavy pressure and vibration, have low friction and can be used where lubrication is less than adequate and there may be minor misalignment.
LB2 bearings require a hardened shaft and maximum shaft surface speeds of 4 m/sec can be tolerated.
The composition of A. W. Fraser alloy LB2 is strictly controlled as are the casting conditions.
Alloy LB2 products are manufactured using the latest continuous and centrifugal casting technology.
Machinability Rating: 95
SAE Grade: 64
