近日，包括美的、格力、海尔在内的多家中国家电巨头联合宣布，将共同推动‘铝代铜’技术标准的制定与落地。所谓‘铝代铜’，是指在空调、冰箱等家用电器的制冷系统中，以成本更低、资源更丰富的铝材部分或全部替代传统的铜管。这一举措旨在应对近年来铜价持续上涨带来的成本压力，同时提升产业链的可持续性和资源利用效率。铜作为传统制冷系统的关键材料，具有优良的导热性和耐腐蚀性，但其价格波动大、资源稀缺。相比之下，铝不仅储量丰富、价格稳定，而且在特定工艺下可实现接近铜的性能表现。然而，铝材在焊接、抗氧化及长期可靠性方面仍面临技术挑战。为此，多家企业正协同科研机构加快材料改性、连接工艺和检测标准的研发，力求在保障产品安全与寿命的前提下实现规模化应用。此次行业联盟的形成，标志着‘铝代铜’从企业个体尝试迈向标准化、产业化新阶段。一旦相关国家标准或行业规范正式出台，不仅将降低整机制造成本，还有望推动绿色低碳制造，助力中国家电行业在全球竞争中占据技术与成本双重优势。
Recently, major Chinese home appliance manufacturers—including Midea, Gree, and Haier—jointly announced their collaboration to advance the formulation and implementation of technical standards for ‘aluminum-for-copper substitution.’ This initiative involves partially or fully replacing traditional copper tubing with aluminum in refrigeration systems of household appliances such as air conditioners and refrigerators. The move aims to address rising copper prices, reduce manufacturing costs, and enhance resource efficiency and sustainability across the supply chain.Copper has long been favored for its excellent thermal conductivity and corrosion resistance, but it suffers from high price volatility and limited global reserves. Aluminum, by contrast, is more abundant, cost-stable, and—when processed with advanced techniques—can approach copper’s performance in specific applications. However, challenges remain in areas such as welding reliability, oxidation resistance, and long-term durability. To overcome these hurdles, companies are partnering with research institutions to accelerate innovations in material modification, joining technologies, and testing protocols.This industry-wide alliance marks a pivotal shift from isolated corporate experiments to standardized, large-scale adoption of aluminum substitution. Once formal national or sectoral standards are established, the transition could significantly lower production costs and support greener, more sustainable manufacturing—strengthening the global competitiveness of China’s home appliance sector through both technological advancement and cost efficiency.
