Superhard materials mainly refer to diamond and cubic boron nitride. Diamond is currently the hardest substance in the world, and the hardness of cubic boron nitride is second only to diamond. The hardness of these two materials is much higher than that of abrasive materials corundum, silicon carbide, tool materials cemented carbide, high-speed steel and other materials. Compared with traditional hard materials tools, diamonds have a longer life, less loss and higher efficiency in industrial processing. Especially, they have unparalleled advantages in processing hard materials. Luo Baihui, Secretary-General of the International Association of Moulds, Hardware and Plastics Industry Suppliers, pointed out that the continued growth and substitution effect of the world industry will continue to promote the expansion of the artificial diamond industry. The domestic production of artificial diamonds has grown rapidly, from 1.6 billion carats in 2001 to 9 billion carats in 2010, with an average annual compound growth rate of 16.4%. China's artificial diamond production accounts for more than 70% of the world's total production.

With the continuous maturity of artificial diamond production technology and the continuous increase of production, the price of diamond products has shown a long-term downward trend, and the highlight of the price-performance ratio continues to promote its replacement of traditional hard materials tools. Among them, the trend of petroleum exploration drills has replaced diamond drills with other hard material drills, which can be corroborated by Jiangduan's performance evolution trend.

The expansion of downstream applications drives the rapid growth of the artificial diamond industry. In the last century, about 50% of artificial diamonds were used to manufacture diamond abrasive tools, but with the advancement of technology and the emergence of new fields of application, the field of use of artificial diamonds has expanded rapidly.

On the one hand, it is the product upgrade in the existing traditional application field, that is, the penetration from the low-end application field to the high-end application field, such as the emergence of polycrystalline composite sheets, which has led to the rapid development of diamond tools, dressing tools, wire drawing molds and other types of diamond tools. And promotion.

On the other hand is the expansion of new application areas. Among them, the space for development in the field of oil bits has been opened. Compared with roller cone bits, PCD bits have a long service life, improve drilling efficiency, and have significant economic benefits. It is estimated that in the next few years, my country will need an average of 40,000 PCD oil drill bits every year. Regardless of the recycling of oil bits, each PCD oil bit requires 30-50 pieces of composite chips (unit price is 200 yuan, based on a conservative estimate of 5% growth rate, China will need about 1.2 million to 2 million pieces of oil each year in the next few years) Composite film, the market size is about 240 million to 400 million yuan.

In addition, in the field of photovoltaic and electronics industry, artificial diamond has also begun to emerge. Among them, wafer cutting and other links in the upstream of the electronics industry have been widely promoted in the Japanese and Taiwan markets. At present, the ascending LED, especially the sapphire cutting link will be another emerging field of diamond cutting lines.

Based on the above factors, there have been obvious influxes of funds in the superhard materials sector recently. Among them, the production of synthetic diamond Sifangda, Henan Diamond, and the Yellow River Cyclone are the most eye-catching performances, which deserves investors' attention.
