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.TZM is a molybdenum-base alloy having good formability and good high temperature properties. It is recommended for structural parts operating at very high temperature levels, as well as for tools such as extrusion dies and die casting cores.
