Cemented Carbide Ball

Cemented carbide ball also known as tungsten ball, pure tungsten ball, pure cemented carbide ball and tungsten alloy ball. Use pure tungsten carbide material is the highest density tungsten carbide ball ball, its density exceeds 19.2g / cm3, and the reasons for the use of pure tungsten carbide ball applicator that has the highest melting point of tungsten carbide ball. Cemented carbide ball is able to used to make shotgun bullets. Shotgun bullets and conventional ammunition different, shotgun cartridges are made ​​by filling a small ball, but when the gun fired the bullet, bullet dispersed into a small ball. The power of gunpowder in the role of each ball, the ball on each of the energy is low. Hunting activities, mainly used for hunting birds or other small animals.

Cemented carbide, chemical formula WC, called the Wolfram Carbide, black hexagonal crystals with metallic luster, hardness close to diamond, electricity, good conductor of heat, melting point 2870 ℃, boiling point 6000 ℃, the relative density of 15.63 (18 ℃). Cemented carbide does not dissolve in water, hydrochloric acid and sulfuric acid, soluble in nitric acid - hydrofluoric acid mixture. Pure tungsten carbide fragile, if incorporated in a small amount of titanium, cobalt and other metals, can be reduced brittleness. Stable chemical properties of tungsten carbide. Tungsten carbide, the carbon atoms in the metal lattice embedded tungsten gap, does not destroy the lattice of the original metal interstitial solid solution is formed, it is also known as interstitial (or insertion) of the compound. Tungsten Cemented carbide can be a mixture of high temperature and carbon is heated in the system, the presence of hydrogen or hydrocarbons to accelerate the reaction. Another is a compound of tungsten carbide and carbon di tungsten formula W2C, a melting point of 2860 ℃, boiling point of 6000 ℃, the relative density of 17.15. Its nature, preparation method, uses the same tungsten Cemented carbide steel, also known as carbide, its hardness second only to diamond, chemically stable, even in the case of heating, nor and hydrochloric acid, sulfuric acid works, even in aqua regia also will not be dissolved. Cemented carbide ball is widely used in water meters, flow meters, pens and other fields.
