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.DI-METAL 3 is a zinc-base alloy of high fluidity capable of producing fine detail in die castings. It is the most stable of the zinc die casting alloys, but on aging loses about 20% of its tensile strength with practically no impact drop.
