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.Lanxide 92-X-2050 is an aluminum-10 Silicon-1 Magnesium-1 Iron alloy with 30 vol.% of silicon carbide particulate. This metal-matrix composite is designed to outperform the unreinforced counterpart. The alloy-matrix composite is available as die castings.
