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 91 Alloy is a cobalt-bearing copper alloy with a small addition of beryllium to make it age hardenable. It has an excellent combination of strength, toughness and electrical conductivity. It is recommended for resistance welding tips and wheels; flash, butt and projection welding dies; springs; slip and collector rings; and electrical components.
