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 A612 is a natural aging aluminum alloy that develops high mechanical properties without a quenching heat treatment. It has high shock resistance and excellent corrosion resistance. It is recommended for highly stressed castings.
