? ? ? ?After entering the 21st century, with China's formal accession to the WTO, China's cemented carbide industry has also developed rapidly under the trend of globalization. In 2013, China's annual output of cemented carbide reached 26,000 tons, an increase of 15.56%. Compared with 2007, cemented carbide production increased by 57.58%. Among them, cemented carbide chips increased by 8.36%, mining alloys increased by 59.33%, wear parts increased by 70.66%, and newly combined gold increased by 23.91%22. The country's major tungsten industrial enterprises achieved an industrial sales value of 18.117 billion yuan, an increase of 6.78% over the same period of 2012.

? ? ? Tungsten carbide is widely used in various manufacturing industries due to its high hardness and wear resistance. The main applications of tungsten carbide in the world include cutting tools (30%), wear parts (28%), high pressure (diamond synthesis, etc.) tools (28%), mining and road construction machinery (11%) and other fields. . With the steady growth of demand for high-performance cemented carbide in the basic industries such as cutting machine tool industry, mining industry, automobile manufacturing, oil drilling industry and electronic information industry, and the continuous expansion of new application fields, the market of cemented carbide in China is expected. Will maintain a growth rate of around 11%.
