Abstract: Aluminum, due to strength to its weight ratio, has more demand in aerospace and automobile sector. Our work focuses on processing and studies of mechanical properties of Al7075-granite powder composite. Stir casting technique is employed for processing. Combination of granite powder (2 wt%, 4wt% and 6wt%) and aluminium has been evaluated for hardness, tensile strength and wear for different loads along with SEM photographs. Ultimate tensile strength, Hardness and wear resistance have appreciably enhanced as compared to the base alloy for a reinforcement of 2%. Whereas for higher percentage it suffers because of agglomeration and porosity.
Keywords: AL7075, Granite, Composite, Stir casting, Wear.
