Abstract: Copper (Cu)–Alumina (Al₂O₃) Metal Matrix Composites (MMCs) have been attracting researchers interest in recent years, since it can provide many advantageous characteristics. Cu-Al₂O₃ composite materials are extensively used as materials for products which require high thermal and electrical conductivities. In our experimental study, copper alumina metal matrix composite reinforced with 5 wt %, 10 wt % and 15 wt % alumina particulates were prepared by the powder metallurgy method. Porosity, XRD analysis, microstructure, hardness, wear resistance, electrical conductivity and corrosion resistance of the composites were evaluated and discussed.

Keywords: copper-alumina MMCs; metal matrix composites; powder metallurgy; P/M; hardness; microstructure; particulate; wear resistance; electrical conductivity; corrosion resistance; porosity.
