Present research uses SiC, TiO2 and Ni-Gr nanoparticles as supplementary additions to enhance overall machining, andmechanical characteristics of derived LM26 aluminium matrix composites. The bottom pouring type stir casting techniquewith the two-step feeding method is employed for the development of proposed Composites. Tensile, micro hardness, andimpact strength as well as metal removal rate (MRR), Tool wear rate (TWR) of electric discharge machining (EDM) wereevaluated to determine the optimal nanoparticle combination that exhibits the best attributes. Results reveal that secondaryreinforcements improve the mechanical performance of the samples significantly. At the same HAMC5 exhibits bettermechanical, and machining performance and reasonable particle distribution. HAMC5 exhibits 35% higher tensile strength,impact and hardness about 88.3 BHN and 53.8 Joules respectively, which is higher than neat samples.
