On July 31, 2026, the "Challenge-Driven"攻坚 Plan project of Wuxi City - "Key Technologies for the Preparation of Lightweight, High-Strength, High-Roughness and High-Conductivity Series Aluminum Materials" was successfully concluded at Yuefeng Aluminum Industry Co.， Ltd. This acceptance meeting was organized by the Wuxi Science and Technology Bureau， and the project's issuing entity， Yuefeng Aluminum Industry Co.， Ltd.， and the project team of the recipient entity， Yuefeng Aluminum Materials Application Research Institute Co.， Ltd.， participated together.
The acceptance meeting strictly followed the "listening to reports, reviewing materials, inspecting the site, and conducting in-depth inquiries" full-process closed-loop review mechanism. During the meeting, the project leader Zhong Guo reported in detail on the project's research background, technical breakthrough route, core indicator achievement, industrialization effect, intellectual property achievements, and financial usage. The expert group carefully reviewed the project summary report, third-party performance test report, patent certificate, standard document, and financial audit report, and conducted on-site inspections of the high-performance aluminum alloy pilot production demonstration line. Regarding key issues such as precise control of alloy composition, optimization of die-casting process, guarantee of mass production stability, and market conversion path, the expert group conducted in-depth inquiries, and the project team provided detailed answers one by one. After thorough discussion and evaluation, the expert group formed the final acceptance opinion.
The expert group unanimously concluded that the project acceptance materials were complete and in accordance with the requirements for municipal-level science and technology project acceptance management.
First, the efforts in core technology research have achieved remarkable results, effectively resolving the domestication bottlenecks in the industry.
The project precisely focused on the urgent demand for lightweight development of new energy vehicles. It targeted the material shortcomings of the three core components of the vehicle body structure, the motor housing, and the cast aluminum rotor. It successfully overcame the key technical challenges in the production of three new materials: non-heat-treated high-strength and high-ductility die-cast aluminum alloy, high-strength and high-thermal conductivity die-cast aluminum alloy, and high-strength and high-electrical conductivity aluminum alloy. It also completed the full-process trial production and comprehensive performance evaluation of typical parts such as the shock absorber tower, the three-in-one motor housing, and the motor rotor. Through third-party authoritative testing, these three types of alloys met all the contractual standards in terms of tensile strength, yield strength, elongation, thermal conductivity, electrical conductivity, and fatigue performance. Some indicators were significantly better than the requirements, effectively breaking the passive situation where high-end vehicle aluminum alloys have long relied on imports.
Second, the innovation achievement system is complete, and the leading and driving role of the industry is remarkable.
During the project implementation period, a total of 5 invention patents were authorized. We participated in the formulation of 1 national standard and 1 group standard, establishing a dual technical barrier of "patents + standards". Simultaneously, we completed the hardware upgrade of the production line and the optimization of the entire process technology, and built a highly automated and traceable high-performance alloy demonstration production line. This resulted in a 15% increase in production efficiency and a 10% reduction in labor costs, with broad prospects for industrialization transformation.
Thirdly, the project's financial management is standardized and transparent, and the funds are used in a compliant and reasonable manner.
The total budget of the project contract is 5 million yuan. After a special audit by Jiangsu Accounting Firm, the actual expenditure during the project period was 4.8683 million yuan, with a budget execution rate of 97.37%. The project funds are accounted for separately and exclusively, and are used for specific purposes only. All expenditures strictly comply with the management regulations for science and technology special funds, and the use of funds is reasonable and transparent, with a standardized and orderly management process.
Based on all the verification results, the acceptance expert group reached a consensus conclusion: This project has fully completed all the research contents and quantitative assessment indicators stipulated in the contract. It has high technological innovation degree, solid industrialization implementation, and significant economic and social benefits. Therefore, it is agreed to be accepted.
The successful acceptance of this project marks another significant achievement of Wuxi's "challenge-proposing and award-winning" mechanism in promoting the research and development of key core technologies in the industry. The developed alloy without heat treatment process eliminates the traditional high-energy-consuming heat treatment procedures. The high thermal conductivity and high electrical conductivity materials significantly enhance the energy conversion efficiency of the motor. By exerting efforts from both the material production end and the vehicle usage end, it achieves carbon reduction throughout the entire life cycle, and combines the dual values of green manufacturing and lightweighting.
Next, the joint parties of the project will take this successful acceptance as a new starting point: continuously accumulate long-term bench test and on-road test reliability data of components, and create benchmark application cases for leading automakers; steadily expand downstream application scenarios such as battery shell and high-speed motor components, and extend the layout to fields such as rail transportation, 5G cooling, and high-end electronics; deeply participate in the formulation and revision of national and industry standards, continuously iterate and optimize alloy formulas and mass production processes, further expand the competitive advantages of domestically produced high-strength, tough and high-conductivity aluminum alloy materials, and provide solid technical support for strengthening and complementing the new material industrial chain of Wuxi's new energy vehicles and the independent control of lightweighting in the domestic automotive industry.
