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.Kaiser Aluminum alloy 7068 has the highest mechanical properties (tensile strength) of the aluminum alloys. It is intended for aerospace, ordnance, and lightweight recreational applications where extremely high strength is required.
