View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.FEDRATED NO. 3 is a tin-base bearing alloy recommended for moderate to high speeds and loads. It has low frictional resistance, low wear, good running-in properties, good emergency behavior upon failing of lubrication, and lower coefficient of expension than the lead-base alloys.
