The preforms are made by taking the aluminum alloy 7075 and filling the SiC, fly ash and graphite reinforcement particles at different Wight percentages (6, 9 and 12)using a stir casting method.The casting performs are machined using conventional lathe machine and different types of cross sections like solid, flange, ring and taper samples are prepared. These samples are tested on UTM and found mechanical compressive properties Max Compressive Strength (MPa), Max Compressive Strain and Young's Modulus (MPa). The axial, compressive and hydro static stress are found using standard analytical equations and same results are validated in ANSYS software, the analytical and ANSYS results are matched very closely. The strength co efficient and strain hardening exponent tell the plastic behaviour of the fabricated performs. For taper and ring type cross section perform samples of 12 weight % of MMC having more ductile compare to other cross sections and other weight % of MMC (6, 9 and base material). And compressive strength is good for the composites compare to the base material AA 7075.
