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.Zr-3Nb-1Sn was developed to provide improved elevated temperature mechanical properties over the Zircaloys without reducing corrosion resistance. It is used in nuclear applications.
