In this study, the effects of boron carbide (B4C) addition on mechanical and physical properties such as microstructure, hardness and density of hot pressed copperboron carbide (Cu-B4C) composites were investigated. To improve the mechanical properties of commercial copper (C) powders having a particle size of 40μm, B4C having a particle size of 40μm, of 2,5, 5, 7,5, 10% by weight was added. Cu-B4C composites were sintered to argon atmosphere at 6500C, 7500C and 8500C for 4 minutes. The electrical conductivity values of the sintered products were measured after examination with the presence of B4C, optical microscope, X-ray diffraction analysis technique and SEM-EDS. In the images obtained, B4C was found to be homogeneously dispersed in the copper matrix. As the ratio of B4C increased, the hardness of the composites increased and the density decreased.
