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.AMPCOLOY 54 is a casting alloy of low-to-medium strength. In the as-cast condition it has a typical tensile strength of 47,000 psi. This alloy has a good combination of strength, ductility, corrosion resistance and wear resistance. Ampcoloy 54 was formerly known as Nickel Gear Bronze. Its uses include gears, fittings, bearings and bushings.
