Metal matrix composites(MMcs) Possess significantly improved properties including high specific strength, specific modulus, Damping capacity and good wear resistance compared to un reinforced alloys. Aluminum Metal Matrix Composites (AMMCs) has extraordinary interest so many applications now a days because of the improvement of phenomenal mechanical, thermal, metallurgical and electrical properties like light weight , better Non-corrosion material, thermal obstruction and high damping limit. The current Investigation project using Tribological attributes of Al 6061 and Al7075 compositions reinforced hybrid with built up SiC and fly ash. Composites were fabricated by stir casting process and studied by using a pin-on-disk apparatus. The reinforcement’s silicon carbide and fly ash were varied with percentages are 5%, 10%, 15% in Al 6061 and Al 7075, to improve the properties of base metal like strength, stiffness, conductivity etc. AMMCs are widely used in aircraft, aerospace, automobiles and various other fields.
