Cubic boron nitride (CBN) has broad application prospects and domestic production capacity is mainly concentrated in central China.

Cubic boron nitride, or CBN for short, is a new type of artificially synthesized superhard material. Its atomic structure is similar to the carbon atomic structure in diamond. It has a hardness second only to diamond and has a high resistance to iron-based metal elements. Chemically stable, it is often used as cutting tools and grinding tools for cutting and grinding iron-based metals.

Cubic boron nitride cutting tools and grinding tools have extremely excellent processing performance. They are not only capable of processing difficult-to-grind materials such as high-temperature alloys, high-speed steel, mold steel, stainless steel, alloy steel, heat-resistant steel, hardened steel, cast iron, etc. It improves production efficiency and workpiece grinding quality, and is also capable of processing complex workpieces such as gear shaping cutters, broaches, high-precision gears, and large precision workpieces such as machine tool guide rails and machine tool screws. Its application fields include automobiles, aviation, machinery wait.

In 2022, the domestic cubic boron nitride cutting tool market size has reached 3.58 billion yuan, accounting for 57% of the total size of superhard cutting tools. Currently, cubic boron nitride has become an irreplaceable superabrasive in modern high-speed precision machining. With the rapid development of the downstream market, its demand continues to increase and its output continues to increase. According to the “2023-2028 Cubic Boron Nitride (CBN) Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center It shows that domestic cubic boron nitride production in 2022 will be approximately 670 million carats.

In addition, cubic boron nitride is also a third-generation semiconductor material with low density, low dielectric constant, high thermal conductivity, high breakdown field strength, super tube band gap, high reflectivity, good wear resistance, With excellent properties such as strong corrosion resistance, strong electrical insulation and good compatibility, it has broad development prospects in fields such as quantum communications, high-power electronics, and deep ultraviolet optoelectronics. In the future, as more advantageous properties of cubic boron nitride are developed, its application fields will be more extensive, and the market development potential is huge.

Superhard materials are strategic emerging industries that are strongly supported by the country. Currently, driven by the strong support of national policies and the growth of market demand, the number of cubic boron nitride companies in my country is increasing and the development speed is accelerating. Domestic cubic boron nitride companies mainly include Henan Borairong Superhard Materials, Henan Yellow River Tornado, Henan Sifangda Superhard Materials, Zhengzhou Abrasives and Grinding Tools Grinding Research Institute, Hefei Jieshijie New Materials, Wuhan Xinrui Alloy Tools, Jingri Diamonds, medium crystal diamonds, etc., there are many companies.

Industry analysts said that from a regional distribution perspective, domestic cubic boron nitride production capacity is concentrated in central China Region, Henan Province’s cubic boron nitride output accounts for about 95% of the country’s total output. The reason is that Henan Province has the only national-level superhard materials industry base in China as well as most research institutions such as Zhengzhou Three Grinding Institute and Machinery Research Institute. At the same time, in terms of policy, the “Henan Province Action Plan to Accelerate Rebuilding and Changing the Advantages of the Materials Industry (2022-2025)” released by the Henan Provincial Government in 2022 clearly includes superhard materials in the category of advanced materials that are focused on development. Favored by various factors, Henan’s cubic boron nitride output will continue to increase, driving the total domestic output to continue to increase, and the industry has a good foundation for development.
