The manufacturing process of tungsten carbide begins with the extraction of tungsten ore, followed by separation and processing to produce pure crystalline products. These are then subjected to vacuum annealing and high-temperature reduction to obtain pure tungsten powder, which is further processed using various carbide powders, bonding agents, metal pressing equipment, and other additives to form green compacts. The powder is then transformed into rough-shaped blanks using processes such as extrusion, powder injection molding, die pressing, and isostatic pressing.

Afterwards, the compacted blanks are sintered into hard alloy billets, and the sintering process determines the actual performance of the resulting tungsten carbide grades. Subsequently, precision grinding is carried out on the surface using precision machine tools to process the dimensions 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.
