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.Nickelvac K-500 is a nickel-copper alloy with age-hardening properties imparted by alloying additions of aluminum and titanium. The alloy is characterized by excellent corrosion resistance in an extensive range of natural and chemical environments, excellent resistance to chloride-ion stress-corrosion cracking, and very high strength and hardness.
