近日，多家国内领先企业联合发起推动‘铝代铜’技术标准落地的倡议，旨在通过制定统一行业规范，加速铝合金导体在电力传输、新能源汽车、建筑布线等领域的规模化应用。‘铝代铜’是指在特定应用场景中，以高性能铝合金材料替代传统铜导体，以降低原材料成本、缓解铜资源依赖，并提升供应链韧性。随着材料科学和制造工艺的进步，新型铝合金导体在导电性、抗蠕变性和连接可靠性方面已显著提升，具备替代部分铜材的技术基础。此次标准制定工作由电力设备制造商、线缆企业、科研机构及行业协会共同参与，将围绕材料性能、连接工艺、安全评估和检测方法等关键环节建立系统化规范。此举不仅有助于消除市场对铝导体安全性和稳定性的顾虑，还将为下游应用提供明确的技术指引，推动产业链协同发展。业内专家指出，‘铝代铜’若能实现标准化、规范化推广，有望每年节省数百亿元原材料成本，并助力国家‘双碳’战略目标的实现。
Recently, a coalition of leading Chinese enterprises has jointly launched an initiative to advance the standardization of ‘aluminum-for-copper’ technology, aiming to accelerate the large-scale adoption of aluminum alloy conductors in power transmission, electric vehicles, building wiring, and other sectors through unified industry norms. ‘Aluminum-for-copper’ refers to replacing traditional copper conductors with high-performance aluminum alloys in specific applications, thereby reducing raw material costs, alleviating dependence on copper resources, and enhancing supply chain resilience. Thanks to advances in materials science and manufacturing processes, new-generation aluminum alloy conductors have significantly improved in conductivity, creep resistance, and connection reliability, establishing a solid technical foundation for partial copper substitution.The standard-setting effort involves power equipment manufacturers, cable producers, research institutions, and industry associations, and will establish comprehensive guidelines covering material performance, connection techniques, safety evaluation, and testing methods. This initiative is expected not only to address market concerns about the safety and stability of aluminum conductors but also provide clear technical guidance for downstream applications, fostering coordinated development across the industrial chain. Industry experts note that standardized and regulated adoption of ‘aluminum-for-copper’ could save tens of billions of yuan annually in raw material costs and support China’s national ‘dual carbon’ (carbon peak and carbon neutrality) goals.
