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.Permendur 24 has a nominal composition of 24% Co and possesses the highest ductility of the cobalt-iron alloy range. Although it requires a higher magnetizing field than the 49% alloy to reach saturation, it finds applications where ductility and price are the prime considerations. It is available as strip or forged section.
