Suitable for gears with heavy loads and slow speeds.
Full alloy description:
A.W. Fraser Alloy AB2 is a nickel aluminium bronze (NAB) conforming to the requirements of B.S. 1400 - 1985 alloy AB2.
AB2 is widely used for marine applications having superior corrosion resistance to marine conditions, high strength, good wearing and erosion resistance.
Corrosion resistance can be further enhanced by annealing of the components [675°C (1250°F) for 6 hours minimum followed by air cooling] before being put into service.
AB2 is suitable for gears with heavy loads and slow speeds and having good lubrication and alignment.
The composition of A.W. Fraser alloy AB2 is strictly controlled as are the casting conditions.
Alloy AB2 products are manufactured using the latest continuous and centrifugal casting technology.
Machinability Rating: 40
SAE Grade: n/a
