The manufacturing process of tungsten carbide begins with the mining of tungsten ore, followed by separation and processing to produce pure crystalline products. The pure tungsten powder is then obtained through vacuum annealing and high-temperature reduction, and further processed with various carbide powders, bonding agents, metal and pressing equipment, as well as other additives to form green compacts.

The powders are then transformed into rough-shaped preforms through processes such as extrusion, powder injection molding, pressing, and isostatic pressing. Afterwards, the compacted billet is sintered into a hard alloy billet. The sintering process determines the actual performance of the tungsten carbide grade obtained. Subsequently, precision machining is carried out on the surface using precision machine tools to process it into finished products, meeting various performance requirements.

Hard alloys can be used to make rock drilling tools, mining tools, drilling tools, measuring instruments, wear-resistant parts, metal molds, cylinder liners, precision bearings, nozzles, etc. The wear-resistant parts made of hard alloys include nozzles, guide rails, plungers, balls, and so on, too numerous to mention.
