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.Federated F070.3 is a heat-treatable aluminum casting alloy recommended for high strength, good corrosion resistance, pressue-tight castings and intricate shapes. It is normally used only when heat-treated (aged) strengths are required.
