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 356.0 is an aluminum casting alloy that normally is used only when heat-treated (aged) strengths are required. It is recommended for high strength, pressure-tight castings, intricate shapes and good resistance to corrosion. Its many applications include gear cases, instrument housings and components for aircraft and missiles.
