                            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 using various carbide powders, metal binders, pressing equipment, and other additives to form green compacts. The powder is then transformed into rough blanks through processes such as extrusion, powder injection molding, die pressing, and isostatic pressing.
      

      
	
      

      
Subsequently, the compacts are sintered to form hard alloy blanks, and the sintering process determines the actual performance of the tungsten carbide grade obtained. Precision grinding is then carried out using precision machine tools to control the dimensions and process them 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. Wear-resistant parts made of hard alloys include nozzles, guide rails, plungers, balls, and so on.
