Inexorably Metal matrix composites (MMCs) improved equities including high mechanical properties compared to unreinforced alloys. There has been an increasing interest in composites comprise low density and low cost reinforcements. Amid various incohesive dispersoids used. The unbiased of this experimental investigation is to produce pure aluminium, as a base material it is reinforced with the following additives each time (silicon carbide Sic,) with different volume fractions. Liquid state mixing proficiency was plugging away for the different integral. A thermocouple is used for checking temperature recurrently whilst unite. To diminish gas bubbles at the final cast degasser was combined to the content of the composite whilst unite. After liquefying and whilst, fluxes were poured in metallic mould then we got a cast from which specimens for numerous tests were prepared. In each case the mechanical properties were steadfast. The sic is accession with matrix alloy, it increases the ultimate tensile strength & the hardness, and decreased elongation of the composites in comparison with particular of the matrix. Waxing wt% of Sic, increased their strengthening effect but sic is the most effective strengthening particulates, for higher hardness, strength and grain size reduction. On the other hand, it decreases ductility and toughness. Further the Vickers hardness test, heat treatment process and microstructures were performed on specimen. The best result has been obtained at 20% weight fraction of sic with pure aluminium.
