This paper discusses the electrical, mechanical, and physical properties of Cu-WC composites. Because of its high electrical and thermal conductivities, low cost, and ease of production, copper is commonly used as a material for electrical connections. Using the liquid metallurgical technique, composites of copper alloy containing 0–8 weight percent WC were created by stirring molten alloy to obtain vortex using a steel stirrer covered with alumina and spinning at 500 rpm. The experimental results showed that as the WC content in the composites increases, the density of the composites increases, which is compatible with the mixtures rule values. The hardness and ultimate tensile strength of Cu–WC composites increased as the WC concentration in the matrix increased, but ductility decreased. A model study of composites was performed for ultimate tensile strength and hardness, and it was discovered that the approximate mechanics of materials prediction Paul model is consistent with experimental results. The experimental results matched the theoretical electrical resistivity of composites data calculated using the P.G Klemens model.
