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.Cuprodie 2 die steel is intended for use without water or oil-based lubricants. Some lubricity is provided by low-melting-point copper alloyed in this grade. The alloy is suitable for hammers where operation without a lubricant/coolant results in low to moderate die operating temperatures.
