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.PFINODAL C72900 is a copper-base alloy that derives its strength from spinodal hardening. It is produced by the manufacturer's wrought powder-metallurgy process for strip metal. This process provides the homogeneity and uniformity needed to achieve fully the available properties of the alloy system. Pfinodal C72900 is available in a variety of tempers. It is used for electronic connectors, switches and springs, especially for those requiring an exceptional combination of strength, thermal stability, formability and corrosion resistance.
