Development of copper:alumina Metal Matrix Composite by Powder Metallurgy method

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.
