China Tungsten High-tech: Building the backbone of China's cemented carbide industry

**Zhuzhou Tungsten and High-Tech Recombination Injection Plant: A Leading Force in China's Hard Alloy Industry** After the hardening and self-hardening of the medium-tungsten high-tech recombination injection plant, it has become a leading enterprise in China’s hard alloy industry. Currently, the company holds approximately 35% of the domestic market share. It controls two major production units—Zhuhard Group and Zizhong Self-Hardening Company—which are the largest and third-largest cemented carbide producers in the country. The company also maintains a strong position in four key sub-sectors of hard alloys. Zhuhard Group is China’s largest cemented carbide producer and one of the 156 key projects from the First Five-Year Plan. With an annual production capacity of 6,000 tons of hard alloys, it covers a wide range of products, including APT, tungsten powder, tungsten carbide, and various types of tools. As the largest and most diversified tungsten enterprise in China, Zhuhard Group operates through two product divisions, 12 production plants, and six holding subsidiaries, such as Zhuzhou Diamond Cutting and Shenzhen Jinzhou Seiko Technology. Zizhong Self-Hardening Company is the third-largest cemented carbide producer and the second-largest manufacturer of cutting blades in China. It has an annual production capacity of around 2,000 tons of cemented carbide, with a broad product range that includes tungsten powder, tungsten carbide, and other specialized materials. The company operates seven production workshops under three holding subsidiaries and two wholly-owned subsidiaries. The company excels in deep processing, particularly in precision tools and micro-drills. Its technological capabilities are among the best in the industry, with advanced R&D centers and international-level testing facilities. Since the 10th Five-Year Plan, Zhuhard has invested over 2 billion yuan to develop new industrial parks focused on metal cutting tools, diamond production, and micro-drilled printed circuit boards. Many of its technologies have reached or surpassed global standards. Zhuhard’s product lineup includes world-class indexable CNC blade lines, solid carbide hole machining tools, and a wide range of precision cutting tools. These tools are used across multiple industries, including automotive, aerospace, and mold manufacturing. Its marketing network spans the entire country and extends to more than 70 countries worldwide. Shenzhen Jinzhou, a subsidiary of Zhuhard, is China’s largest high-tech enterprise in the design and production of carbide drills, milling cutters, and precision molds. It has over a decade of experience in micro-drilling and precision mold manufacturing, with a technical level that leads the domestic industry. The company produces ultra-small drill bits as small as 0.02mm and offers a comprehensive range of high-quality cutting tools tailored to customer needs. Both Zhuzhou Diamond Cutting and Shenzhen Jinzhou are significant contributors to the company’s profitability. In 2013, their net profits accounted for a large portion of Zhuhard Group’s total earnings, highlighting their importance in the company’s financial structure. In 2014, Zhuhard signed a cooperation letter of intent with Sandvik, a global leader in cemented carbide and tool manufacturing. This partnership aims to establish a joint venture focused on cutting tools, enhancing Zhuhard’s global competitiveness. Minmetals Group, the actual controller of the company, has committed to building a complete tungsten industry chain over the next three years, including mining, smelting, powder production, and deep processing. Although the company already possesses a full supply chain from APT to hard alloys, it still lacks direct access to tungsten mines. However, Minmetals remains the largest supplier of tungsten ore in China, ensuring a stable raw material supply for the company. With a strong market presence, advanced technology, and strategic partnerships, Zhuhard continues to strengthen its position as a leading player in the global hard alloy and tungsten industry.
