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 712.0 is a high-strength aluminum casting alloy that is self aging at room temperature. It has good machinability, good dimensional stability and good resistance to corrosion and shock. Among its applications are marine castings, high-strength pressure-tight castings, aircraft components and cylinder heads.
