Diamond overall boom

The demand for diamonds is growing at a high rate, and the overall prosperity is rising. On November 11th, the first China International Abrasives Grinding Exhibition was officially opened at Zhengzhou International Convention and Exhibition Center. The audience was very popular and popular. It was the first time that China's abrasives grinding industry held such exhibitions. It can be seen that the industry is this year. It has only shown a huge scale, which has not yet attracted everyone’s attention. The cost of hard materials such as synthetic diamonds has led to the replacement of traditional abrasives such as silicon carbide, and it is this structural alternative that has brought the diamond industry into the current boom cycle. As new downstream applications continue to emerge, the industry as a whole is on the rise. Low-end diamond products are now over-capacity. Zhongnan Diamond, the country's largest diamond manufacturer, currently has an annual production capacity of 4.6 billion carats, which is more than 1 billion carats compared to last year. The third-ranked Yu Diamond is expected to exceed 1.2 billion carats this year. There are still large expansion plans announced in the future. The exhibition found dozens of small and medium-sized enterprises with a capacity of less than 500 million carats. The price of low-end products has dropped from 0.30 yuan/carat to 0.20 yuan/carat. The overcapacity of low-end products has begun to appear. We visited large-scale press equipment manufacturers on the spot and found that the equipment is completely localized, and the capital expenditure for expansion is not large. Therefore, it should be said that there is not much barrier to the production of low-end products, and capacity expansion is relatively easy. Low-end products can be converted into diamond micro-powder, turning waste into treasure. At the scene, dozens of companies producing micronized powder were seen, and the industry concentration was lower than that of diamond. However, we are delighted to discover that the high-end products of micro-powder are a high-tech barrier and a high value-added segment. For example, special powder for diamond wire, it has been found that leading enterprises export to Japanese diamond wire enterprises at a speed of 80-100 million carats per month. In the future, with the gradual application of domestic diamond cutting lines, it will usher in a broad market space, and the current export sales The price can reach 3 yuan / carat. A major application of high-end micronized powder is the production of PCD composite sheets, and further knives can be made to replace traditional hard alloys. The price of such micro-powders can also reach 1-2 yuan/carat. Even micro-powder companies can produce nano-polycrystalline micro-powder, which sells for up to 10 yuan per carat. These high-end micro-powder products can be said to turn low-end diamonds into treasure, while at the same time alleviating the danger of low-end diamond overcapacity, it is worthy of attention. The policy is positive. On the one hand, diamond-related industries have been included in the “12th Five-Year Development Plan for New Materials”, and the development of super-hard materials has affected the improvement of the overall industrial production level in China. On the other hand, Henan Province is China's superhard material production and accumulation area, and the official approval of the Central Plains Economic Zone will enable Henan's superhard materials industry to receive more policy support. During the exhibition, the ministers of the Ministry of Industry and Information Technology, who participated in the approval of the Central Plains Economic Zone, and the leading enterprises such as Airborne Yu Diamond, highly expected their development.
