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.DURALCAN W2A.xxA-T6 is a heat-treatable wrought aluminum alloy metal-matrix composite, where xx represents the volume percent of alumina particulate, Al2O3. The base alloy is 2014 (Alloy Digest Al-185).
