Abstract: In the present industrial scenario, Aluminium and its alloy based composites have more importance in the growing fields of engineering. Aluminium reinforced metal matrix composites are broadly speaking desired because it has the excessive strenth along with less weight, hardness, corrosion resistance, fatigue and creep resistance. The Al composites are focused to use in aerospace, automobile and also in structural domain because it gives good strength with less weight. This paper discussed about the mechanical residences of Aluminium 7075 alloy strengthened with SiC and TiC. Stir casting process was utilized for fabrication of composites and composite specimens are subjected to tensile test by using Universal Testing Machine. The composite hardness was tested by using Brinell hardness tester and the Charpy impact tester used for findings the impact strength. An experimental results are compared with unreinforced alloy of Al 7075. Micro structural characterization confirms the particles of reinforcement are distributed to the entire structure of matrix. The experimental result shows the mechanical properties slightly increased by varying wt% of reinforcements in the matrix material. The better tensile strength (252MPa), hardness (83HB) and impact strength (4.6 Joules) is obtained by the composition of 60% wt of Al 7075, 20% wt of TiC and 20 %wt of SiC.
