Full alloy description:

A. W. Fraser Alloy 953 is an aluminium bronze conforming to the requirements of UNS C95300.

Alloy 953 is a medium strength aluminium bronze having a low iron content, thus being less likely to damage shafts.

This alloy has good ductility and machinability and good general corrosion resistance, making it suitable for pump and valve components.

Under certain conditions, notably in crevices and under stagnant non aerated conditions, this alloy may suffer dealuminification.

Alloy 953 is suitable for light-medium duty gears and nuts where loading is negligible.

The composition of A. W. Fraser alloy 953 is strictly controlled as are the casting conditions.

Alloy 953 products are manufactured using the latest centrifugal casting technology.
Machinability Rating: 35
SAE Grade: 68B

Comparable specifications:

AS1565 C95300; ASTM B505, B271 - C95300; SAE J461
