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.AMCROM is an oxygen-free copper containing chromium. It can be precipitation hardened to enhance its strength and to increase its electrical conductivity. AMCROM is produced by adding chromium to oxygen-free copper. AMCROM copper contains fewer inclusions than conventional chromium copper and as a result, has greater ductility and uniformity. Typical applications of AMCROM include resistance welding electrode tips and wheels, electrical contacts and connectors and high-temperature wire.
