The material selection criteria involve the requirement of high strength and good corrosion resistance aluminum alloys for the matrix materials. The mechanical properties have been determined for different metal matrix composites produced from Al 6061, Al 6063 and Al 7072 matrix alloys reinforced with silicon carbide particulates. The yield strength, ultimate strength, and ductility of Al/SiC metal matrix composites are in the descending order of Al 6061, Al6063 and Al 7072 matrix alloys. Mg has improved the wettability between Al and SiC particles by reducing the SiO2 layer on the surface of the SiC. The fracture mode is ductile in nature.
