Recently, Yuefeng Aluminum Processing has once again received industry-wide authoritative recognition for its innovative achievements and collaborative research and development efforts: The project "Integrated Precision Manufacturing Technology for Residual Stress Evolution and Forming of Large Aircraft Components Based on Aerospace Aluminum Alloy" led by Nanjing University of Aeronautics and Astronautics and with Yuefeng Aluminum Processing as the core application unit, successfully won the third prize of the 2026 China Aeronautical Society Science and Technology Award for Science and Technology Innovation. This fully demonstrates the technical strength and comprehensive transformation capabilities of the enterprise in the precise manufacturing of aerospace aluminum alloy thick plates.
It is known that the China Aeronautical Society Science and Technology Award is a highly influential authoritative technology-specific honor in the aviation field, focusing on original breakthroughs, engineering application effectiveness, and industrial driving value in the aerospace science and technology field. It is an important benchmark for evaluating the technological innovation level and collaborative research and development capabilities of the aviation industry. The award focuses on selecting scientific and technological achievements with strong originality, high engineering application value, and significant industrial empowerment effects, highlighting the development level of technological innovation and industrialization integration in the aviation field.
This project focuses on the optimization of high-speed milling process for 7xxx high-strength and high-toughness aluminum alloy thick plates, addressing the domestic demand for high-precision manufacturing of large aerospace components. It tackles industry challenges such as uneven residual stress after quenching, insufficient pre-stretching for stress relief, milling flutter of thin-walled parts, and processing deformation induced by stress in the billet. In the collaborative research and development, Yuefeng Aluminum Processing undertakes the core industrial verification, preparing multiple groups of 7xxx aluminum alloy thick plates with different residual stress levels for experimental samples, providing physical verification samples for the simulation model under production conditions, and breaking the data loop between theoretical simulation and industrial production. The team has pioneered the "experimental reverse simulation optimization verification" integrated path, establishing a form and shape integrated manufacturing system covering quenching, pre-stretching, aging, and high-speed milling processes, and implementing supporting intellectual property layout. This award-winning achievement is a phased result of Yuefeng Aluminum Processing's comprehensive research and development efforts on residual stress control for all series of high-end aluminum alloys. The project's complete set of technologies has laid a technical foundation for the research and mass production of 7xxx ultra-large section aluminum materials and has reserved industrial processes and verification experience for stress regulation of 2xxx, 5xxx, and 6xxx special aluminum alloy plates.
Looking to the future, Yuefeng Aluminum Processing will continue to adhere to innovation-driven development, continuously improve the research and development matrix covering all grades of aerospace aluminum alloys for residual stress control, significantly increase investment and patent cultivation in aerospace aluminum alloy new materials and advanced high-speed milling manufacturing processes, deepen collaborative innovation in research and development and the industrial chain, consolidate and expand cooperation achievements with universities and research institutions such as Nanjing University of Aeronautics and Astronautics, continuously break through core technical bottlenecks of various series of high-end aerospace aluminum materials, and use independent core processes to support the transformation and upgrading of China's aerospace metal processing industry. This will lay a foundation for high-end lightweight materials for domestic aerospace equipment autonomy and the construction of a manufacturing power, and demonstrate the material innovation strength of the enterprise in the aerospace industry's high-quality development process.
