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 905 is a Tin Bronze or "G" Bronze conforming to the requirements of ASTM B505/B271 alloy C90500.
905 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 905 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 905 is strictly controlled as are the casting conditions.
905 products are manufactured using the latest continuous and centrifugal casting technology.
Machinability Rating: 50
SAE Grade: 62
