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.BISBO is a pearlitic malleable iron readily cast in thick sections with consistently high mechanical properties. It has high yield strength, excellent wear resistance, and adaptability to selective hardening.
