this study, copper-tungsten carbide composite was produced by mechanical alloying and powder metallurgy. The compaction pressures were varied from 100 to 600 MPa for observation on microstructure and properties of the composite. The result showed the microstructure was densified with the increased of compaction pressure. Within compaction pressure no fracturing was occurred. Increasing compaction pressure increased the density, hardness and electrical conductivity of the composite which related to the reduced of porosity area.
