Fabrication of high strength and good corrosion resistance properties aluminum alloys is still a challenge. In the same direction, different composite materials were fabricated with different grades of Al alloy 6063, 6066, and 6351 reinforced with silicon carbide particulates. The SiC particles were added in different percentage and resulting composite cast were tested for the hardness. The fracture mode of the cast was found to be ductile in nature and the hardness of aluminum alloys with addition of SiC increases. In addition, during fabrication Mg was added between Al and SiC particles to improve the wettability and reduces the formation of SiO2 layer on the surface of SiC.
