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.CBX CUPRON ALLOY is a resistance alloy with practically constant resistance over the range of -67 to 221 F. The alloy does not generate gas when in contact with glass, enamel or ceramic type materials, an advantage over CB CUPRON (Constantan).
