Abstract
Abstract Some variables that in turn help improve the properties of copper, whether mechanical or physical, were studied. Copper was reinforced with carbide with excellent properties from WC and with different volumetric enhancement ratios (0,1.5,3,4.5,6) %. The powders were mixed and milled for a two-hour time, as the samples were pressed at (5) tons for a time of one minute, after which the prepared samples appeared at 950°C and for a time only two hours, various tests were conducted on the samples for the purpose of studying their physical and compositional properties and included a diffraction examination X-ray, real and apparent porosity, real and apparent density, compressive strength. The results were encouraging and gave the best values after sintering and at a 6% WC boost, if the minimum true porosity was 13.31%, while the apparent porosity was 9.22%, while the real density value was10.72g/cm 3 , and the highest apparent density was 11.22g/cm 3 . The radial compressive strength value is 132.7MPa.
