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 220 is widely used as a base material for cathodes in electronic receiving tubes. Its composition is controlled closely because this is necessary for all alloys produced especially for use in cathodes. Nickel 220 is effective where fairly easy activation is required without liberating excessive amounts of barium.
