Innovative Forum on Magnesium Alloys in Auto Industry Launched in Changchun for Sustainable Development

July 08, 2024

On April 28, the China Association of Automobile Engineering Automotive Products Subcommittee (CAAE APS), the China Foundry Association's Auto Parts Casting Subcommittee, the First Auto Works Manufacturing Technology Society, the Changchun Auto Economic and Technological Development Zone Science and Technology Bureau, and FAW Casting Co., Ltd., five key organizations, co-hosted an innovative forum on magnesium alloys in the auto industry in Changchun. The forum brought together renowned experts and scholars from prestigious institutions like Jilin University, Shanghai Jiao Tong University, Hebei University of Technology, Baowu Magnesium Industry, the Chinese Academy of Sciences' Institute of Physical Chemistry, and Yizhi Machinery.

According to the "Made in China 2025" blueprint for automotive development, lightweight materials remain a top priority. Magnesium alloys, currently a hot topic in research and application, boast similar mechanical properties to aluminum with a density 2/3 that of aluminum and 1/4 that of steel. This makes them highly advantageous for lightweight industry applications due to their high strength-to-weight ratio and stiffness. Furthermore, magnesium alloys exhibit superior damping, vibration reduction, and electromagnetic shielding, making them suitable for various automotive interior components such as CCB frames, dashboard frames, seat frames, door panels, and sunroof frames. Improvements in technology have addressed issues with corrosion resistance, enabling wider use in motor housing, battery casings, shock towers, wheels, and underbody structures, with even the possibility of integration into monolithic floor structures.

During the forum, experts from academia, research institutes, and industries delved into key challenges, showcasing the latest advancements in magnesium alloy manufacturing, including materials, processes, equipment, surface treatments, and joining technologies. These findings offered valuable insights for lightweight automotive applications.

The forum served as a catalyst for fostering interaction among stakeholders in the magnesium alloy supply chain, establishing an industrial application alliance, and promoting a synergy of academia, industry, and research. Moving forward, the CAAE APS aims to strengthen collaboration between FAW and academic institutions, research centers, and related companies, tackling core technological hurdles, accelerating the adoption of research outcomes, and expanding the market for magnesium alloy products in new energy vehicles. This collaborative effort will drive the modernization of the auto industry, boost the nation's manufacturing prowess, and significantly contribute to the growth of the new energy vehicle sector and the construction of a manufacturing powerhouse.
