The upstream raw material market of my country's superhard tool industry is highly competitive and well-supplied, mainly concentrated in the fields of polycrystalline 

diamond, cubic boron nitride and its composite sheets, large-size single crystal diamond, etc. Well-known foreign manufacturers include Element Six of the United Kingdom, 

Iljin Group of South Korea and DI Company of the United States, while domestic companies include Zhongnan Diamond, Yellow River Cyclone, Sifangda and many others. 

China has a global resource advantage in the field of superhard materials. At present, diamond production accounts for more than 80% of the global total production, and 

cubic boron nitride production accounts for more than 60%. From 2020 to 2022, China's annual production of artificial diamonds will reach 14.874 billion carats, 16.235 

billion carats and 16.295 billion carats respectively, making it the world's largest producer of superhard materials.

In terms of downstream applications, superhard tools are widely used in many industries, including display screens, touch screen cutting, electronic product shell processing, 

automobile key parts manufacturing, aerospace, military industry and new energy equipment and parts processing. Among them, the automotive industry is the largest 

application market for superhard tools, accounting for nearly 70%. The rapid development of new energy vehicles has driven the demand for lightweight car bodies. The use 

of lightweight materials such as aluminum alloys in automobile manufacturing has increased significantly, further promoting the rapid growth of the superhard tool industry.

Despite the rapid development of the domestic superhard tool industry, European, American and Japanese companies still dominate. Internationally renowned companies 

such as Sweden's Sandvik, the United States' Kennametal and Japan's Sumitomo not only have advanced technology, but also provide full industrial chain services from 

upstream materials to downstream products, with strong competitiveness. Although the number of domestic superhard tool manufacturers has exceeded 1,000, mainly 

concentrated in economically developed regions such as the Yangtze River Delta, the Pearl River Delta and the Bohai Rim, they started relatively late and gradually expanded 

the market mainly through cost-effective advantages.
