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 F430 is a heat-treatable aluminum-copper-silicon casting alloy with good castability, machinability and corrosion resistance. It is produced by sand casting and is a general-purpose alloy recommended in both the as-cast and heat-treated conditions.
