Key features:

For bearings or bushings under light loads and high speeds. Suits if bearing metal must deform slightly to conform to irregular motion or perfect fit. Effective when lubrication is difficult.


Full alloy description:

A. W. Fraser Alloy 941 (EMS 403) is a high leaded tin bronze which conforms to the requirements of AST M B505 - C94100.

This alloy has excellent bearing qualities and good corrosion resistance.

Alloy C94100 is suitable for moderately loaded bearings with low working temperature and low impact loading or pounding.

It will withstand doubtful lubrication for short periods. Adequate backing for bearings must be provided.

The micrograin casting techniques used in the manufacture of this alloy ensure good lead dispersion and small particle size with lead globules typically less tha n 120μ” (.005”).
Machinability Rating: 80
SAE Grade: n/a
