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.ALLVAC 8A1-1Mo-1V alloy is predominantly alpha in microstructure, aluminum being the alpha stabilizing component and giving the alloy the lowest density of all commercial titanium based materials.
