Jiangsu Mrisen has successfully developed 9N ultra-high purity copper, helping China to reach a new peak in the field of high purity materials

  On May 29,2025, Jiangsu Kunshan —— China's high-purity metal materials industry achieved a historic breakthrough! Jiangsu Mrisen New Materials Co., Ltd. (hereinafter referred to as "Mrisen") announced that the company successfully developed 9N ultra-high purity copper on May 29,2025. This achievement marks a significant technological leap in the field of high-purity copper and represents a new milestone in the development of China's high-purity metal industry. It also solidifies "Mrisen's leading position in the global high-purity technology sector.

  Mrisen has consistently focused on the research and development and production of ultra-high purity metals, specifically those with a purity level of 7N and above. The successful preparation of 9N ultra-high purity copper is a testament to the company's technical team's long-term efforts in overcoming challenges and continuous innovation. According to the analysis by the authoritative third-party testing institution ——PAT, the product has reached a purity level of 9N, which is the highest limit for instrument detection of high-purity metals, with impurity control levels leading globally. The first batch produced one ton, and the product's performance surpasses international standards.

Technological breakthrough: the limit jump from 7N to 9N

  As a national high-tech enterprise specializing in ultra-high purity metal technology, Mrisen has always adhered to the core philosophy of "achieving what others cannot and surpassing what others can." Since its establishment, under the leadership of Chief Scientist Professor Zhou, the company has developed a globally leading 7N high-purity copper production line using its independently developed "target impurity removal." The products are widely used in advanced fields such as semiconductor targets, superconducting magnets, new energy, aerospace, and other cutting-edge areas. The successful development of 9N ultra-high purity copper marks a significant advancement in the company's high-purity metal purification technology. This breakthrough also demonstrates the company's strong capabilities in technological innovation and process optimization, reflecting its relentless pursuit of high-quality products. Meanwhile, Professor Zhou stated:"This purity level has reached the limit of current detection equipment, providing a material foundation that was previously unattainable for cutting-edge technologies such as semiconductors and controlled nuclear fusion devices."

Promote industry development and power China's domestic substitution strategy

  China's high purity metal market has long relied on imports, and foreign manufacturers occupy a monopoly position in the field of high purity metal production by virtue of advanced technology, which leads to many restrictions for Chinese enterprises in raw material supply. Mrisen's successful development of 9N ultra-high purity copper is of great significance for promoting the localization process of China's high purity metal industry.

  On one hand, this helps to break the foreign technological blockade, reduce our reliance on imported high-purity metals, enhance the self-reliance and control of Chinese industries, and ensure national industrial security. On the other hand, it provides high-quality, reliable raw materials for advanced industries such as semiconductors, superconductors, and aerospace, thereby boosting our competitiveness in the global high-tech sector and facilitating our transition from a major manufacturing country to a leading manufacturing power.

Application prospects: enabling the domestication of high-end industries to break through

  The emergence of 9N ultra-high purity copper material will strongly support advanced manufacturing processes in high-tech fields such as semiconductors, superconductors, and Tokamak devices for controlled nuclear fusion in China, laying the foundation for breaking through technical barriers of relying on imported high-end materials. Currently, the company's high-purity products have established cooperation with multiple semiconductor enterprises in China, helping to achieve localization substitution in key process links.

  The successful development of 9N ultra-high purity copper is another new starting point in the journey of Mrisen in the field of high purity metals. The company will continue to increase investment in research and development, constantly explore and innovate production processes, strive to improve product quality and performance, and move forward towards more extensive application goals.

  At the same time, the company will actively expand its market presence, enhance cooperation and communication with both domestic and international clients, and promote advanced high-purity metal materials and technologies to a broader audience. We believe that with the joint efforts of outstanding Chinese enterprises like Mrisen, China's high-purity metal industry will usher in an even more brilliant future, making greater contributions to high-tech development in China and around the world.
