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.ALUMINUM A850.0 is an aluminum bearing alloy containing nominally 2.5% silicon for improved casting characteristics. It is used extensively in the T5 temper for heavy-duty applications, such as large rolling-mill bearings. It is particularly suitable for this application because of its anti-scuffing characteristics, low friction and high resistance to wear under conditions of boundary and thin-film lubrication.
