Description

Tungsten carbide is a black-gray crystal with hexagonal structure composed of tungsten and carbon. It has metallic luster and hardness similar to diamond. It is a good conductor of electricity and heat. Because of its high hardness, high wear resistance, high melting point and other characteristics, it is widely used as a hard alloy in cutting tools, micro drills in the electronics industry, precision molds, and medical equipment Chemicalbooks. Tungsten carbide is chemically stable, insoluble in water, hydrochloric acid and sulfuric acid, and easily soluble in a mixed acid of nitric acid and hydrofluoric acid. Pure tungsten carbide is fragile. If a small amount of titanium, cobalt and other metals are added, the brittleness can be reduced. Tungsten carbide used as a steel cutting tool is often added with titanium carbide, tantalum carbide or their mixture to improve the anti-knock ability.

Tungsten carbide powder is used in cemented carbide production materials and used to produce DLC coatings (diamond-like carbon). This type of coating is extremely hard and long lasting and protects Chemicalbook's engine and other auto parts from wear under high stress. By reducing the coefficient of friction, DLC coating can extend the life of gears, stamping dies and many other components.
