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.NIMOCAST Alloy 80 is the casting counterpart of NIMONIC* Alloy 80A (Alloy Digest, Ni-10, May 1954). It may be used as as cast but develops optimum mechanical properties in the fully heat treated condition. NIMOCAST Alloy 80 is used for diesel engine precombustion chambers and for other high-temperature components.
