Cemented carbide industry chain from a relatively long, from the initial tungsten ore to the final carbide and its products industry chain can achieve a larger value-added space. Preliminary estimates, from the initial raw material concentrate powder into metal powder, product value-added about 3 times; from concentrate powder to ordinary hard alloy, can enhance the added value of products about 6 times; from concentrate powder to CNC lathe rotating blade, product value-added more than 20 times.

China's cemented carbide industry started from the 1950 s and has gone through nearly 60 years of development of technology introduction, digestion and absorption, and independent innovation. Domestic cemented carbide enterprises have gradually developed and grown, both in terms of quantity, scale and technology have made great progress. As the market has gone through the extensive development in the early stage, cemented carbide enterprises have gradually attached importance to R & D and innovation capabilities, and the awareness of intellectual property protection has been continuously enhanced. The patent work in the cemented carbide industry has grown from scratch and has developed rapidly. At present, there are more than 30 universities and research institutes engaged in cemented carbide research in China, and the proportion of technical personnel is about 10%.

According to the patent application data of cemented carbide industry, the growth rate of new patents in cemented carbide industry began to grow rapidly around 2006 and reached its peak in 2014. In 2006, the number of new patents for cemented carbide in China was only 169, and by 2014, the number of new patents had reached 661.
