On October 28th, the ultra-high precision 2050 aluminum-lithium alloy profiles developed by Yuefeng Aluminum and evaluated and researched by the China Aviation Manufacturing Technology Research Institute were successfully passed the installation review. They will be officially applied to aircraft structural components. This is the company's first aluminum-lithium alloy product to pass the aviation field installation review, marking a "milestone" step for Yuefeng Aluminum to empower aviation equipment with its core strength in aluminum-lithium alloy materials and fulfill the mission of "industry patriotism".
The ultra-high precision 2050 aluminum-lithium alloy profiles approved for installation were independently developed and produced by Yuefeng Aluminum. They innovatively adopted strong flow transformation extrusion near-net-shaping technology, replacing the traditional sheet metal mechanical processing route. The forming accuracy is benchmarked against mechanical processing, and the material utilization rate and production efficiency have been significantly improved. At the same time, compared with traditional 7050 high-strength aluminum alloy, it can achieve a weight reduction of more than 5%. It is a typical new quality productivity achievement.
Aircraft structural components have strict standards for material stability, forming consistency, and service reliability. From component design, process breakthroughs, to test verification and installation review, the R&D and production team of Yuefeng Aluminum directly faced the industrialization difficulties of the third-generation aluminum-lithium alloy, continuously refined the casting, extrusion, heat treatment, and surface treatment complete set of processes, and connected the key links from material research to installation application, achieving the engineering breakthrough of domestic aluminum-lithium alloy profiles in aircraft structural applications, and successfully opening up a new track for aviation equipment support.
The implementation of this achievement further solidified Yuefeng Aluminum's technical and industrialization advantages in the high-end aluminum-lithium alloy field, laying a solid foundation for meeting the lightweighting requirements of more aircraft models. Facing the new journey of national strength construction, Yuefeng Aluminum will continue to focus on aerospace advanced materials and component manufacturing, adhere to independent innovation, continuously promote the series and scale production of aluminum-lithium alloy and other lightweight materials and components, develop efficiently and cost-effectively, continuously overcome "key technology" difficulties, the innovative practice of "form and nature coordinated manufacturing" and "extreme manufacturing" concepts support the iterative upgrade of aerospace equipment, and continuously develop new quality productivity, contributing more to the development of core technologies and equipment and self-reliance and strength of our country!
