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.The Microcast-X process produces a finer grain size than earlier produced castings which improves mechanical properties in IN-718 without negative impact on rupture properties in temperatures of interest for applications in the aerospace market.
