A process of making an article of a tungsten-carbide-cobalt alloy with or without an additive of one or more of tantalum, cobalt-nickel, nickel-tantalum, tantalum-carbide, titanium-carbide, niobium-carbide, chromium-carbide, titanium-nitride and diamond dust. The method includes forming a homogeneous mixture of polygonal-shaped powder tungsten-carbide-cobalt and a polygonal-shaped powder additive and a binder including wax and a high molecular weight polyolefin polymer and injecting the mixture under heat and pressure into a metal injection mold to form a green preform of the article. The green preform is immersed in a linear hydrocarbon or a halogenated hydrocarbon or mixtures to dissolve and remove the wax and convert the green preform into a brown preform which is sintered to remove the remainder of the binder and to densify the brown preform into an article having a density not less than 98%. Various tungsten-carbide articles are disclosed.
