【SMM Aluminum Flash News】Yongzhen's 6D05 Aluminum Alloy Gains National Approval and Registration
Recently, Yongzhen Co., Ltd.'s independently developed 6D05 aluminum alloy grade successfully passed the review of the National Technical Committee for Standardization of Nonferrous Metals, officially completing the national grade registration and being included in the national nonferrous metal alloy grade system. The development of the 6D05 alloy was led by the Yongzhen Research Institute, with the research team covering multiple professional areas including material composition design, extrusion process, testing and verification, and standardization application. In June 2024, the 6D05 alloy officially started large-scale production, simultaneously advancing downstream customer testing and verification. On November 26, 2025, Yongzhen completed the preparation of a complete set of technical documents, third-party testing reports, sales certificates, application effect descriptions, and other materials, and submitted an application for registration of the nonferrous metal and alloy grade to the National Technical Committee for Standardization of Nonferrous Metals. From April 20 to July 20, 2026, the grade application entered the national public announcement stage. On August 7, 2026, after review and approval by the National Technical Committee for Standardization of Nonferrous Metals, the 6D05 grade was officially registered. The 6D05 alloy is an innovative design based on the traditional 6005 aluminum alloy, which achieves a comprehensive improvement in material performance through the empowerment of trace elements.
