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.LUMDIE is a tungsten-chromium hot work steel recommended for die casting dies, forging and extrusion dies. It is an air hardening steel having high temperature properties and heat resistance. It is particularly suited for long run die casting dies, brass forging dies, and for various extrusion tools such as dummy blocks, dies, and mandrels.
