Carbide minning bit is made of refractory metal hard compound and binding metal by a synthetic material. Carbide mining bit has high hardness, high temperature resistant, great corrosion resistance, abrasive resistance and toughness, and a series of excellent charcteristics. Under the high temperature of 500 ℃, they can remain the same hardness and shape. At 1000 ℃, they still have the very high hardness. There are more than 50 countries in the world who produce the cemented carbide. The output can reach 27000 ~ 28000 tons, mainly coming from China, Switzerland, the United States, Russia, Sweden, Germany, Japan, Britain, France. The carbide market is in the saturated state and the basic market competition is very fierce.
