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.C.D.C. Manganese Alloy No. 772 offers a combination of high strength and ductility. It has a high temperature coefficent of expansion, high electrical resistivity, low thermal conductivity, and high vibration damping constant.
