Against the backdrop of ongoing automotive lightweighting, aluminum alloys are rapidly expanding into more application scenarios such as structural body parts, battery packs, and chassis systems. Among them, 6-series aluminum alloys, which combine strength, formability, corrosion resistance, and lightweighting advantages, have become one of the key directions for automotive aluminum development. As NEVs raise higher requirements for vehicle safety, driving range, and manufacturing efficiency, the market is posing new challenges to the overall performance of 6-series aluminum alloys. How can the balance between material strength and toughness be further improved? How can formability, joining performance, and service reliability be balanced? How can the new demands brought by the continuous upgrading of automotive manufacturing processes be met? These questions are becoming a key focus for the automotive materials industry... Against the backdrop of the continuous upgrading and iteration of automotive aluminum alloy materials, we are honored to have invited Dr. Zhu Xiao, R&D Director of Liaoning Xiangyu Aluminum Co., Ltd., to attend the SMM (8th) Automotive Supply Chain Conference and deliver a keynote speech titled —— " Performance Iteration Direction of 6-Series Aluminum Alloys in the Automotive Sector ," combining industrialization implementation experience to share solutions for the R&D, process optimization, and mass production of next-generation 6-series aluminum materials tailored for NEV complete vehicles. Dr. Zhu Xiao is a senior engineer, a high-end manufacturing talent recognized by the MIIT, and a high-end industrial talent under Liaoning Province's "Xing Liao Ying Cai" program. He is primarily responsible for the development of new products, new technologies, and new processes at Xiangyu Aluminum, the application of engineering technologies, science and technology projects, and intellectual property-related work . Over the past five years, he has led five national and provincial-level scientific research projects, including those under the National Key R&D Program and Provincial Science and Technology Major Projects, won the Liaoning Province Science and Technology Progress First Prize twice, obtained over 50 nationally authorized patents, and published more than 30 papers, achieving multiple technological breakthroughs in the forming and product processing of high-end aluminum alloy materials . Focusing on automotive lightweight material upgrades, secure this practical knowledge-sharing session, and explore with top aluminum material R&D experts the opportunities for the iterative development of 6-series aluminum alloys.
