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.

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.
