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.DuraFoil-Clad is a laminate composite form of DuraFoil (see Alloy Digest, SS-892), a heat-resistant ferritic stainless steel with excellent oxidation resistance for high-temperature applications. The material is a metallurgically bonded Al/Fe-Cr stainless steel/Al metallic composite. The material should be converted to a uniform solid-solution alloy (the single alloy form DuraFoil) by diffusion alloying before service in high-temperature applications.
