摘　　要：In this investigation, the addition of several amounts of metal oxide particles (CuO₂) in Al matrix is carried out due to the need to improve the mechanical properties such as the ductility of aluminum for applications in the electrical sector. Samples were obtained by means of a stirring casting process. From the results of the microstructural characterization, it was observed that the metallic oxides induce the modification of the dendritic structure and grain refinement. X-ray diffraction characterization mainly shows the formation of Al₂CuO₄, Al₂O₃ and CuO compounds. Mechanical properties showed that the different thermal treatments resulted in an improved hardness, from 30 kg/mm² for the un-reinforced sample to 90 kg/mm² for reinforced samples. The addition of metallic oxides in the Al matrix produces an improved electrical conductivity specifically in sample with 0.50 g of CuO₂ additions.In this investigation, the addition of several amounts of metal oxide particles (CuO₂) in Al matrix is carried out due to the need to improve the mechanical properties such as the ductility of aluminum for applications in the electrical sector.
