Recently, the Wuxi Science and Technology Commission, the Science Park Management Committee, and other five departments officially announced the list of Wuxi City's New Technologies, New Products, and New Services (the 20th batch). The two automotive lightweighting key technologies proposed by Yuefeng Aluminum Materials Institute, namely "Key Technology Development and Industrialization Application of the Overall Battery Replacement Assembly for New Energy Trucks at the Bottom" and "Research and Application of Key Technologies for Aluminum-Substitute Steel Full Aluminum Body Lightweighting", were successfully selected into the High-End Equipment and Manufacturing New Technologies after being strictly reviewed by experts and multi-level re-examination and public announcement. This marks that the company's related scientific and technological innovation achievements have received professional recognition and authoritative certification.
The two selected achievements fully demonstrate the technical research and industrial application capabilities of Yuefeng Aluminum Materials Institute in the field of automotive lightweighting. Among them, "Key Technology Development and Industrialization Application of the Overall Battery Replacement Assembly for New Energy Trucks at the Bottom" independently developed 6E21 aluminum alloy, with core indicators reaching international advanced levels. This technology overcomes bottlenecks such as alloy research, section optimization, and welding deformation control, innovates the battery replacement frame structure, and has been applied in scenarios such as long-distance logistics, ports, and mining areas, and has the ability to expand to passenger car body parts and rail transit fields.
"Research and Application of Key Technologies for Aluminum-Substitute Steel Full Aluminum Body Lightweighting" achieved a 20% - 30% reduction in body structure weight, and further improved the torsional stiffness and shear strength of SPR joints. The project overcame core processes such as the optimization design of aluminum and steel heterogeneous materials, and the control of high-strength aluminum alloy forming cracking, solving the problems of high manufacturing difficulty, unstable connection quality, and high manufacturing costs of traditional aluminum body manufacturing. The related achievements have been mass-produced in the aluminum structural components of mainstream new energy vehicle bodies in China.
It is understood that the recognition of new technologies, new products, and new services in Wuxi City began in 2014, aiming to select innovative achievements that are in line with the scientific and technological development direction of the capital, have industry-leading roles, and have industrialization implementation value. This provides enterprises with authoritative technical endorsements and helps them expand the market and connect industrial resources. So far, a total of 21 batches and over 20,000 new products, new technologies, and new services have been recognized and released, promoting the deep integration of scientific and technological innovation and industrial development.
The selection of these two technical achievements into the list of new technologies, new products, and new services of Wuxi City not only fully affirms the company's technical research and achievement performance, but also lays a foundation for subsequent market promotion and industrial-scale application. In the future, Yuefeng Aluminum Materials Institute will continue to focus on the innovation track of aluminum-based new materials, promote the industrialization implementation of research and development achievements such as new high-strength aluminum alloys, heterogeneous connection, and overall structure integration technologies in the field of new energy vehicles, and contribute to the high-quality development of Beijing's advanced manufacturing and continuous empowerment of China's lightweight technology innovation and industrial upgrading.
