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.EASTERN Z-METAL is a cast ferrous alloy that possesses a unique combination of high strength, machinability, wear resistance, and toughness. Its microstructure consists of temper carbon nodules dispersed through a uniform matrix of spheroidite and ferrite. This alloy is made in several different grades.
