This research technically aims at utilizing stone dust as reinforcement to check the mechanical properties of Al(6063) with different weight ratio of the reinforcement. The alloy consisting of 0, 2, 6 and 10 wt% of the reinforcements were produced using double stir casting method. Evaluation of the microstructure, percentage porosity check, measurement of density and mechanical properties of the composites produced were used to check the performance levels of the composite produced. The results obtained show that the microstructure of the composite produced shows no discrepancy as the reinforcements were evenly dispersed in the matrix. The measured density of the composites decreases with an increase in the reinforcement. Hardness value increases with an increase in the reinforcement from 38.9-60 BHN with 12%, 56% and 74% respectively of the composite produced over the unreinforced sample.
