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 514.0 is a non-heat-treatable alloy containing nominally 4% magnesium. It has relatively low strength and hardness. It is characterized by excellent weldability and excellent resistance to corrosion. Aluminum 514.0 is recommended for food-processing equipment and marine applications.
