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 F460 is a heat treatable, aluminum-base, sand and permanent mold casting alloy having good foundry characteristics and pressure tightness. It is recommended for general purpose castings in either the as-cast or heat treated condition. The F460PT grade is specially processed during manufacture to reduce the apparent solidification shrinkage with no change in chemical specification or mechanical properties.
