Unleaded hard bronze with excellent wearing properties. Preferred for guides, bushings operating at very high loads at low speed, gears and worms.
Full alloy description:
A.W. Fraser Alloy G1 is a gunmetal conforming to the requirements of B.S. 1400 - 1985 alloy G1.
G1 has good machining properties, medium hardness, good strength and good wear resistance.
This material has good corrosion resistance, especially to seawater, making it suitable for marine applications requiring a higher strength material.
Bearings manufactured from G1 require good reliable lubrication and a hard shaft, and are suitable for medium to heavy loadings at low speed.
The composition of A.W. Fraser alloy G1 is strictly controlled as are the casting conditions.
G1 products are manufactured using the latest continuous and centrifugal casting technology.
Machinability Rating: 50
SAE Grade: 62
