Zigong Cemented Carbide Co., Ltd. (referred to as "Zighard") was founded in 1965. It is the first large-scale cemented carbide manufacturer independently designed and constructed in China. In July 2006, Hunan Nonferrous Metals increased its capital and shares. The self-hardening company carried out property right system reform; in 2010, China Minmetals, a Fortune 500 company, successfully acquired Hunan Nonferrous Metals, and the company became one of the core members of the cemented carbide and tungsten and molybdenum industries under China Minmetals Corporation.
At present, self-hardened company has a registered capital of 870 million yuan, an asset scale of 1.87 billion yuan, and more than 2,500 employees . It has 3 branches, 5 holding subsidiaries, and 5 alloy business divisions, including branches in North America and Europe. . After more than 50 years of development, the company has continuously formed an industrial layout with cemented carbide as the main body and hard facing materials and tungsten and molybdenum products as the two wings. Products are widely used in machinery, metallurgy, petroleum, mining, construction, electronics, aerospace and other fields. Based in the southwest, facing the whole country and radiating to the world , the company continues to build a multi-level and multi-channel marketing network. 40% of its products are exported to more than 40 countries and regions such as Europe, America, Japan, South Korea, Southeast Asia, the Middle East, and Russia. It has a post-doctoral scientific research workstation and a provincial technology research and development center with advanced equipment and complete functions. It is the first batch of national intellectual property demonstration enterprises and has obtained more than 300 authorized patents. Focusing on the transformation to modern scientific development, the company has successively passed system certifications such as quality, environmental management, occupational safety and health, energy management, quality inspection, and measurement control. It has successively won important honors such as "National May 1st Labor Award", "National Customer Satisfaction Enterprise", "China Famous Trademark", "China Famous Brand Product" and "National Green Factory".
Committed to the common cause of "Innovation and Self-improvement, Great Wall of Excellence", to the "One Body with Two Wings" industrial sector strategy and the "Number One" product development strategy, and to creating a "distinctive, domestically leading cemented carbide and supporting tool manufacturer ; domestic first-class refractory metal manufacturer, leading enterprise in China's tungsten and molybdenum industry; world-leading surface engineering materials, international advanced comprehensive provider of surface engineering application services", self-hardened company has established three major industries in Zigong and Chengdu respectively base:
Cemented carbide industry: mainly located in Da'an District, Zigong City. It has a complete R&D and production system from powder to cemented carbide and deep processing and supporting tools. It has world-leading sophisticated equipment. Mineral alloys and tools, wear-resistant parts and finishing products, etc., the domestic market share is about 10%. Among them, the scrap rate of precision parts customers has dropped to less than three per 100,000, reaching world-class; road construction tools have been favored by important customers such as the United States and Japan; focusing on the future needs of intelligent manufacturing fields such as aerospace and automobiles, A CNC blade production line has been established, with a production capacity of 10 million pieces in 2021.
Hard facing material industry: Located in the High-tech Industrial Park of Zigong City, it mainly covers the production and application of tungsten-based hard facing materials, world-leading thermal spraying, surfacing (cladding), infiltration and other composite materials and supporting application services The system is an important field of today's additive manufacturing and green remanufacturing industries. The domestic market share is 40%, and the international market share is 20%. At present, hard surface materials have obtained AS9100D aviation, aerospace and defense organization management system certification; surface strengthening technology services and application products have successfully entered the field of nuclear power applications.
Tungsten and molybdenum products industry: located in Chengdu National Economic and Technological Development Zone, has introduced advanced technology and equipment from Japan, the United States, Germany and other countries, and built tungsten powder, tungsten rod, tungsten alloy, tungsten wire, molybdenum rod, sprayed molybdenum wire, The manufacturing system of series products such as wire cutting wire has strong technical development, marketing and innovation and development capabilities. Among them, molybdenum wire ranks first in the industry, and tungsten wire has established long-term cooperative relations with internationally renowned companies. The product quality, scale and market share are all leading in China.
Facing the future, as an important backbone subsidiary of China Minmetals and a backbone enterprise of China's tungsten and molybdenum industry, Self-hardened Company will continue to hold high the mission banner of "revitalizing China's tungsten industry and bravely climbing the world's peak", and will closely focus on the national "14th Five-Year Plan" "Development planning and industrial policy, efficiently docking with the overall strategy and goals of China Minmetals and China Tungsten High-tech, always adhere to one center (centered on efficiency), two strategies (one body with two wings of the industrial sector strategy, one of the best product development strategies) , The high-quality development of the three orientations (market orientation, target performance orientation, and problem orientation) is fundamentally followed, without delay or slack for a single day, and is constantly moving towards the strategic goal of "domestic leadership in comprehensive strength, world-class superior products", Continue to contribute more self-improving strength to the progress of the industry, the prosperity of the country, and the rejuvenation of the nation.
