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.Nickel 270 is a high purity nickel exceptionally free from non-metallic inclusions. Its low hardness and good ductility permit heavy cold deformation without reannealing.
