Aluminium alloy as a matrix of the composite is quite attractive among researchers because of the light weight, high ductility and exceptional corrosion resistance. In this research paper, a stir casting furnace setup is prepared for the fabrication of hexagonal boron nitride and alumina reinforced aluminium matrix composite. A ccomparative evaluation of the mechanical properties of aluminium based single and hybrid reinforced aluminium matrix composites are carried out. Two specimens of single reinforced aluminium matrix composites are fabricated using 5% and 10% hexagonal boron nit-ride in the matrix of AA7075 aluminium alloy by stir casting method. Other two specimen of the hybrid composites are fabricated with the addition of 2% and 4% Nano alumina in excess to 10% hexagonal boron nit-ride. The reinforcement is preheated up to 3000 c. Subsequently, Mechanical characterization such as hardness testing, and impact testing are done on all the four specimen and a comparative study of the testing has been done.
