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.Harvey HA-7146 is an alpha-beta type titanium-base bar and forging alloy developed to combine high temperature strength and stability with good forgability. It is recommended for aircraft gas turbine engine components due to its improved stress stability and creep resistance. It responds to an age hardening heat treatment.
