Composite superhard materials have broad prospects

The composite superhard material industry is a subdivision of the superhard material industry. In addition to the composite (polycrystalline) superhard material industry, the superhard material industry also includes the single crystal superhard material industry (single crystal diamond/cubic nitride) boron material). Materials such as diamond and cubic boron nitride are collectively referred to as superhard materials due to their extremely high hardness, while composite superhard materials mainly refer to single crystal superhard materials such as diamond and cubic boron nitride powder as the main raw materials, adding metal or Non-metallic binder is a polycrystalline composite material made by ultra-high pressure and high temperature sintering process. Composite superhard materials are widely used in traditional fields such as machinery, metallurgy, geology, petroleum, coal, stone, wood, construction, automobiles, home appliances, etc., as well as high-tech fields such as electronic information, aerospace, national defense and military industries. Materials in the middle and downstream of the superhard material and its product industry chain include polycrystalline diamond (polycrystalline cubic boron nitride) and polycrystalline diamond (polycrystalline cubic boron nitride) composite sheets, which have three main uses: one is as a Cutting tool material; the second is the cutting tooth of the petroleum geological drill; the third is the high-grade wire drawing die used for the preparation of wire drawing.

The development prospect of composite superhard material industry is optimistic. The composite superhard material is a new type of material required for industrial production and processing with extremely significant characteristics. It has unique functions and great hardness, and is difficult to be replaced by other materials. Moreover, the production process and process of composite superhard materials are relatively mature. Affected by government investment, the petroleum industry, construction industry, metal cutting machine tool and automobile industry have experienced long-term substantial growth. The rapid and stable growth of the composite superhard material end-user market will surely bring greater development opportunities to the composite superhard material industry. and broad market space. In addition, compared with traditional materials such as cemented carbide, composite superhard materials have the advantages of higher hardness, better wear resistance, higher thermal conductivity, and better processing performance, which make them better in service life, processing quality and The processing efficiency and other aspects are excellent, which greatly exceeds the traditional cemented carbide materials, so it has obvious advantages in replacing the traditional super cemented carbide materials.

At present, the mid-to-high-end products in the global composite superhard material manufacturing industry are mainly monopolized by companies from the United States and Japan, and most of the mid-to-high-end market shares are dominated by DI, Element Six, U.S. Synthetic, Japan’s Sumitomo, and South Korea’s It is controlled by leading international group companies such as Rijin. However, my country's superhard material industry is large but not strong, especially in the field of composite superhard materials. For a long time, foreign famous enterprises have occupied the high-end market. There is a clear gap between Chinese enterprises and foreign famous enterprises in terms of output and quality. Some products need to be imported, so there is a huge demand for import substitution in the field of domestic superhard materials. Investors are advised to pay attention to the leading companies in domestic composite superhard materials.
