With the global economy recovering and the sustained growth of the domestic macroeconomy, key industries such as petroleum, construction, metal cutting machinery, and automotive have experienced rapid development. This has significantly increased the demand for composite superhard materials among end users. The growing trend is expected to create more opportunities and expand market space for the further development of the composite superhard materials industry.
First, the market for PCD (Polycrystalline Diamond) composite sheets used in oil and gas drill bits is largely driven by the demand for oil and gas exploration tools. As China’s oil and gas production continues to rise, so does the demand for diamond composite sheets in this sector. Currently, the global market for PCD composite sheets in the oil and gas industry is approximately 11 billion yuan, with China accounting for around 1.4 billion yuan. The future potential of this market remains very promising.
Second, the demand for PCD composite sheets in coal mining and industrial tools is closely tied to the volume of coal extracted. With increasing coal production, the market for diamond composite sheets in mining is expanding. Globally, the market for mining composite sheets is nearly 20 billion yuan, with China holding a share of about 2 billion yuan.
Third, the high-grade PCD drawing die blanks are in demand due to the extensive use of wire rods in industrial and construction projects. However, due to high production costs and prices, their adoption is still limited. Only a few high-precision applications currently use these blanks, indicating that there is significant room for market expansion.
In recent developments, Warren Buffett’s interest in acquiring Suntech sparked a surge of optimism in the global capital market. Now, his acquisition of the remaining 20% stake in Israeli metalworking tool supplier IMC is likely to drive a re-evaluation of the value of superhard materials. In the A-share market, investors are paying attention to companies like Yellow River Whirlwind, Boshen Tools, and Sifangda.
Yellow River Whirlwind (600172) has undertaken 32 national and provincial scientific research projects, holding over 70 core independent intellectual property rights in the field of synthetic diamond large-tonnage presses. It has won numerous awards for technological progress and holds over 100 patents. The company leads in R&D for advanced areas such as large particle synthetic diamonds and super-hard composite films. It is now a global manufacturer of superhard materials with a comprehensive product range.
Boshen Tools (002282) has invested in several technology transformation projects, including a high-performance laser welding diamond tool project and a low-noise construction machinery initiative. These projects aim to increase production capacity and improve profitability. The company currently produces millions of diamond tools, small construction machines, and hard alloy tools annually.
SFD (300179) specializes in the development, production, and sale of composite superhard materials. It is the largest producer of polycrystalline diamond (PCD) in China, with products widely used in petroleum, mining, drawing dies, and cutting tools. Its product portfolio includes PCD compacts, polycrystalline cubic boron nitride composites, and PCD drawing blanks.
