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.Nicrofer 7016TiAl (also known as alloy 751) is an age-hardening Ni-Cr-Fe alloy with both good corrosion resistance and high rupture strength. It is a slight modification of alloy Nicrofer 7016TiNb (alloy X-750) and is used in diesel exhaust valves.
