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.COOPER PH-55B is a high-strength high-ductility alloy recommended for corrosion resistance of parts subjected to a combination of stress and shock. It responds to an age-hardening heat treatment.
