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.TECHALLOY Nickel 200 is commercially pure wrought nickel. It maintains good strength at elevated temperatures and is tough and ductile at low temperatures. It is a general-purpose material when the properties of nickel alloys are not needed. Its many uses include spun and cold-formed parts, electrical components, transducers and nickel-cadmium batteries.
