The composite super-hard material industry belongs to the sub-sector industry of the super-hard materials industry. In addition to the composite (polycrystalline) super-hard material industry, the super-hard material industry also has the single crystal super-hard material industry (single crystal diamond/cubic boron nitride 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 micropowder as the main raw materials, adding metal or A non-metallic binder is a polycrystalline composite material produced by an ultrahigh pressure 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, and other high-tech fields such as electronic information, aerospace, and defense. The materials in the middle and lower positions of the superhard material and its product chain are polycrystalline diamond (polycrystalline cubic boron nitride) and polycrystalline diamond (polycrystalline cubic boron nitride) composite sheets, which have three main purposes: Cutting tool material; second, as the cutting teeth of petroleum geological drill bits; third, high-grade drawing die for preparing wire drawing. The development prospects of the composite superhard materials industry are optimistic. The composite super-hard material belongs to a new type of material which is characterized by extremely remarkable industrial production and processing. It has unique functions, great hardness and is difficult to be replaced by other materials, and the production process and process of the composite super-hard material are relatively mature. Affected by government investment, the petroleum industry, construction industry, metal cutting machine tools and automobile industry have experienced long-term substantial growth. The rapid and stable growth of the composite super-hard materials end-user market will definitely bring greater development opportunities to the composite super-hard materials industry. And vast market space. In addition, composite superhard materials have the advantages of higher hardness, better wear resistance, higher thermal conductivity and better processing performance compared with traditional materials such as cemented carbide, which make them in service life, processing quality and Excellent processing efficiency and other aspects, greatly exceeding the traditional cemented carbide materials, so it has obvious advantages in replacing traditional superhard alloy materials. At present, the mid-to-high-end products of the global composite superhard material manufacturing industry are mainly monopolized by companies in the United States and Japan. Most of the mid-to-high-end market share is led by DI, Element Six, American Synthetic, Sumitomo, and Korea Rijin. Controlled by the group company. However, China's super-hard materials industry is not strong, especially in the field of composite super-hard materials. For a long time, foreign famous enterprises have occupied the high-end market. Chinese enterprises have obvious gaps with foreign famous enterprises in terms of output and quality. Some products need to be imported, so the demand for import substitution in the field of domestic superhard materials is huge. Investors are advised to pay attention to leading companies in domestic composite superhard materials.
