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 D132 is an aluminum permanent mold casting alloy recommended for applications where good high-temperature strength, low coefficient of thermal expansion, and good resistance to wear are required, such as automotive and diesel pistons.
