AbstractA composite of copper powder reinforced with SiCp (0-10 wt%) in which
aluminum powder of ( 2 wt%) was added for improving wettability of the ceramie phase. . The composite mixture was prepared by mixing with a ball mill for one hour to ensure a homogenous distribution on the composite .Gteen compacts pressed at (350MPa) a steel mold of (12mm)diameter were then sintered at (900 °C) for two hours in an electric furnace, in argon atmosphere . Optical microscopy,
Density, porosity content and Vicker's hardness test were then conducted for the sintered samples. Obviously, it was concluded that there was enhancement of the physical and mechanical (hardness) properties of the sintered compacts with increasing the SiC content.
