China Cemented Carbide Turn Losses Into Gains In a Quarter of 2016

According to the 54 companies’ statistics show that, a quarter of cemented carbide production is about 4590.6 tons, down 4.95%; the community did not consider the statistical data, it is estimated the country carbide production of about 5500 tons. Among them, the export cemented carbide 1288.91 tons, an increase of 1.62%; cemented carbide deep-processing products output 768.13 tons, down 17.11 percent. Carbide industry total revenue of 2.83 billion yuan, down 21.12 percent; wherein the main business income of 2.798 billion yuan, down 20.95%; to achieve profits of 168 million yuan, an increase of 25.73%; profit of 18.1355 million yuan, an increase of 66.9304 million yuan; cemented carbide exports $ 65,755,500, down 38.25 percent.

Cemented carbide also called tungsten carbide, tungsten cemented carbide or simply carbide. Cemented carbide (WC) is an inorganic chemical compound containing equal parts of tungsten and carbon atoms. It can be pressed and formed into shapes from fine gray powder, which is considered to be its most basic form. Cemented carbide is approximately three times stiffer than steel, with a Young's modulus of approximately 550 GPa, and is much denser than steel or titanium. It is comparable with corundum or sapphire in hardness and can only be polished and finished with abrasives of superior hardness such as cubic boron nitride and diamond among others, in the form of powder, wheels, and compounds.

Cemented carbide is the preferred material for parts that must withstand all forms of wear (including sliding abrasion, erosion, corrosion/wear and metal-to-metal galling) and exhibit a high degree of toughness. It exhibits high compressive strength, resists deflection, and retains its hardness values at high temperatures, a physical property especially useful in metal-cutting applications.
