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.6092/SiC/17.5P is a discontinuous metal-matrix composite fully characterized for discontinuously reinforced alloy (DRA) structural applications. The base alloy is Aluminum Association 6092, and the reinforcement material is SiC.
