Fly ash particles are potentially used in metal matrix composites, since they are low-cost, low-density and available in large quantities as a waste by-product in thermal power plants. The addition of fly ash into aluminum as reinforcement can potentially reduce the production cost and density of aluminum. However, mechanical properties of fly ash reinforced aluminum matrix composite (MMC ALFA) have some limitations due to the characteristic of fly ash. In this study, a carbothermal reduction process of fly ash with activated carbon powder was performed prior to produce MMC ALFA. The carbothermal reduction process was carried out in a furnace at 1300 oC in vacuum condition. The product was analyzed by XRD with Cu-Ka radiation. The synthesis product was subsequently used as reinforcement particle. Aluminum powder and 5, 10 and 15 % wt of carbothermally reduced powder were mixed and then uni-axially compacted at pressure of 300 MPa. Green body was sintered for 2 hours in argon atmosphere at temperature of 550 and 600 oC. Hardness, wear resistance and density of MMC ALFA’s product were tested using Brinell hardness test, ogoshi high speed universal wear testing machine and Archimedes method respectively. The results of this study shows that the reinforcement of carbothermally reduced of fly ash in general can improve the hardness and wear resistance of MMC ALFA. From XRD analysis, it shows that the synthesis process can produce SiC powder
