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.Alcan 2196 T8511 is produced as extrusions for applications where compression is critical. 2196 Al-Li alloy, with high strength and elastic modulus but low density, is used for floor beams, seat tracks, welded applications, and wing stringers.
