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.Hiperco Alloy 15 is a development in soft magnetic alloys that combines the properties of high saturation, magnetization, high electrical resistivity, and lower cobalt content.
