Hunan Yongrui Material Technology Co., Ltd.

    Hunan Yongrui Material Technology Co., Ltd., located in the Yiyang High-Tech Development Zone in Hunan Province, a national-level high-tech development zone, is an innovative high-tech enterprise integrating scientific research and development with industrial demonstration.
    The company's legal representative is Mr. Liu Wei, formerly a senior engineer at the Institute of Mining and Metallurgy and a member of the institute's expert committee. As a recognized innovative new materials enterprise in Hunan Province, the company has established a dedicated R&D facility. Engineering and technical personnel dedicated to new product development and researching new machining technologies and processes account for 33% of the company's workforce. The company boasts an innovative R&D team primarily comprised of senior engineers, supplemented by engineers. These R&D personnel specialize in materials science, heat treatment, metallurgical engineering, and other fields, creating a highly complementary professional structure. Furthermore, the company has hired Professor Liu Zhijian, Director of the Institute of Functional Materials at Central South University, as Chief Scientist. The company's R&D team boasts strong innovative capabilities and is a typical, multi-disciplinary, knowledge-based technical team.
    The company's leading product, high-chromium cast iron composite wear-resistant material, is a key material widely used in industries such as mining, metallurgy, power generation, cement, sugar production, brick making, and road construction to resist wear and reduce metal loss. This material is a composite wear-resistant material composed of a highly hard, high-chromium cast iron layer and a highly tough, conventional base layer, achieving an effective metallurgical bond. The introduction of this functional gradient concept enables the product's performance to surpass the limits of single metal materials, effectively resisting all types of wear under harsh operating conditions. This effectively addresses the issues of traditional wear-resistant materials, such as limited wear resistance, low material utilization, and inflexible assembly and replacement. The product is widely used in mining machinery, crushing machinery, sugar refining machinery, environmental protection machinery, and engineering machinery, reaching internationally advanced standards.
    The company is committed to the innovative research and application of wear-resistant materials. In 2019, the company independently developed a ceramic high-chromium cast iron composite wear-resistant material that successfully addressed the formation mechanism of ceramic-metal composites, overcoming challenges in ensuring uniform distribution and morphological control of ceramics in high-chromium cast iron. This technology exponentially improves the wear resistance of the high-chromium cast iron composite wear-resistant material. This technology is a domestic first and a leading technology in the wear-resistant materials field. With a total investment of 6 million yuan, the company has established a complete wear-resistant material composite production line. The company's current turnover reaches 10-12 million yuan, with annual tax revenue reaching 600,000-700,000 yuan.
    The company's products are sold exclusively to the international market, with customers in countries such as the United States, Australia, Canada, Belgium, Brazil, Chile, and Kazakhstan. Its products are primarily used as accessories and protective parts for mining machinery, construction machinery, grinding machinery, stone crushing machinery, sugar refining machinery, automobile recycling machinery, and construction waste recycling machinery. The company has become a renowned international supplier of wear-resistant materials and solutions for wear problems. With the continuous introduction of new products, its market share is steadily expanding.
