AbstractCopper, which is known to have very good electrical and thermal conductivity, has poor mechanical properties. In order to overcome this negativity, the production of coppermatrix composites is becoming increasingly popular. In this study, copper (Cu) matrix ferrochromium (FeCr) and ferroboron (FeB) reinforced composites were produced. Cold pressing and sintering process were preferred as production methods. Microstructure and phase composition of the composites were examined by using scanning electron microscope (SEM). Hardness properties were carried out microhardness device. Also, Densities of composites were studied. SEM images showed that FeCr and FeB reinforcements were partially homogeneously dispersed in the Cu matrix. In the presence of FeCr and FeB in the Cu matrix, the hardness of the Cu matrix was considerably increased.
