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.Nimonic 80 and Nimonic 80A are nickel-base alloys containing a high percentage of chromium, with aluminum and titanium as hardening agents. They are made to the same compositional specification, but Nimonic 80A is produced to meet a more severe requirement with respect to resistance to creep when stressed at higher temperatures than Nimonic 80. Both alloys show high strength at high temperature levels and are very resistant to scaling, oxidation, heat and corrosion.
