There has been a rapid growth in the utilization of Aluminium alloys in the recent era especially in automotive and aerospace industry because of their inherent properties like high strength to weight ratio, low wear rate, etc. Hybrid MMC’s are new generation advancement in composites. This project uses Al7075 alloy as matrix metal with boron carbide and tungsten carbide as reinforcement particles. Stir casting process was used to fabricate the composites by varying the mass fractions of boron carbide (2-6wt%) and tungsten carbide being constant (4wt%).This paper investigates the mechanical property, tribological behavior and microstructural analysis of the composites prepared as per the ASTM standards which is used to evaluate the performance of the composite. Vickers hardness test was performed and the hardness value significantly increases with increase in the percentage of boron carbide and as the hardness of composite increases the wear rate reduces. The density of the composites is similar to that of Al 7075 alloy with slightest deviations
