Abstracts: In the present study, silicon carbide particulate reinforced LM6 alloy matrix composites were produced by gravity die casting process by varying the particulate addition by weight fraction on percentage basis. Mechanical properties such as tensile,yield,Hardness and elongation tests were conducted to determine the tensile strength, ductiliy and yield strength characteristics of cast MMC’s. Micro structural properties of the as cast composites have also studied by using optical microscope. The experimental result reveals that the tensile property increases with increase in Sic upto 15% weight,but drastically reduces above 15%.
