AbstractPure aluminum has a specific gravity of about 2.7 g/cm3. Low specific gravity is important in the aircraft and automobile industry and in all transportation industries [1]. The composition of commercially pure aluminium Al %97,200, Si %0,569, Fe %Is 0.253 FR %0,428, Mn %0,100 Mg %0,697 Ti %0,063, Zn %0,093 Cr %0,161, Pb %0,461 it consists of [2]. Metal matrix composite (MMC) materials have superior physical and mechanical properties such as high elastic modulus, strength, abrasion resistance and high temperature properties [2]. The MMC in comparison with metallic materials with high strength/weight ratio, high temperature, creep and fatigue resistance and dimensional stability, in comparison with PMC high strength, stiffness, operating temperature, thermal and electrical conductivity, as well as the contribution of pollution are materials that are at a very low level. For this reason, MMC, they are widely used in many areas such as aerospace and automotive. [3]. In this study, commercially pure aluminium has been used as a reinforcing material in particulate metal matrix and B2O3. Pure aluminium 0,5%, 1% B2O3 particle reinforcement is made. B2O3 glassy and porous. B2O3 glassy at room temperature, has a low hygroscopic (%1). Porous compared absorb less moisture. In this study, two cases have been studied. The resulting metal matrix composite optical microscope, SEM (scanning electron microscope), wear and hardness (Vickers) tests were applied.
