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 6025 HT is a high-carbon Ni-Cr-Fe alloy with a face-centered cubic microstructure. The alloy has additions of aluminum and yttrium to enhance oxidation resistance. The alloy is age-hardenable for additional strength.
