Tungsten carbide is chemically stable, insoluble in strong acids such as water, hydrochloric acid and sulfuric acid, but readily soluble in a mixture of nitric acid-hydrofluoric acid. Pure tungsten carbide is fragile, but its brittleness can be reduced by doping a small amount of titanium, cobalt and other metals.

Due to its excellent properties such as high hardness, high wear resistance and high corrosion resistance, tungsten carbide is the main raw material for the production of cemented carbide, which is widely used in cutting tools, molds, wear-resistant parts and other fields. Tungsten carbide coating has excellent wear resistance, impact resistance and corrosion resistance, and is used for surface treatment of bearings, valves, pumps and other parts.

Tungsten carbide is a kind of metal carbide with excellent performance, which plays an important role in the fields of cemented carbide manufacturing, coating materials, aerospace, oil and gas and so on. In the aerospace field, tungsten carbide is used in the manufacture of high-temperature components, such as nozzles for jet engines and blades for gas turbines. In oil and gas extraction and processing, tungsten carbide is used to manufacture drill bits, nozzles and other components to improve their wear and corrosion resistance.

Tungsten carbide has a wide range of applications in many occasions due to its excellent properties such as high hardness, high wear resistance and high corrosion resistance. Tungsten carbide is the main raw material for manufacturing tungsten carbide tools (such as drills, milling cutters, turning tools, etc.). These tools play a key role in metal processing, wood processing, stone processing and other industries, and are able to cut a variety of materials efficiently and accurately. In mold manufacturing, tungsten carbide is also often used to make mold cores, punches, mold inserts, etc. to improve the wear resistance and service life of molds.

Tungsten carbide is usually prepared by carbothermal reduction, powder metallurgy or chemical vapor deposition. Among them, powder metallurgy is one of the most commonly used methods, which is made by mixing tungsten and carbon powders, pressing them into shape, and then sintering them at high temperatures. This method is not only a mature process, but also capable of producing tungsten carbide products with complex shapes and excellent performance.
