Abstract—

Aluminum matrix composites (AMCs) become choice for automobile and aerospace industries due to its tunable mechanical properties such as very high strengthto weight ratio, superior wear resistance, greater stiffness, better fatigue resistance, controlled co-efficient of thermal expansion and good stability at temperatures. Nowadays Al7075 having high priority in aircrafts, rock climbing and cycle industries. The present work study is focused on hybrid metal matrix composition of Al7075 with Boran nitride (BN) as 0.5% constant throughout the composites and Aluminium Oxide (Al2O3) as 1%, 2%, 3%, 4%. Stir casting is highly used in industries for hybrid composites. Aluminium will be converted into molten phase and add the reinforcement materials by using mechanical stirrer as per proposed composition and then pour the molten metal into the required patterned die. That fully developed cylindrical bars are tested to find out the mechanical properties of desired composites to compare with pure Al7075. By examining all the results tested on different composition of specimens, the specimen of 3%Al2O3 have the efficient mechanical properties than compared with pure aluminium, 1%, 2%, 4% .
