Xin Lang Cai Jing·2025-12-14 09:13Core Viewpoint - Major air conditioning companies including Haier, Midea, Xiaomi, and TCL have committed to adhering to the "Self-Discipline Convention" for aluminum reinforcement in air conditioning, while Gree Electric has notably not joined this initiative, indicating a divergence in industry strategy regarding the "aluminum replacing copper" technology [2][3][5]. Group 1: Industry Commitment and Standards - The "Self-Discipline Convention" aims to enhance the industry's overall image and competitiveness, promoting the transition to aluminum in air conditioning systems [2]. - A significant focus at the 2025 China Home Appliance Technology Annual Conference was the innovation and standardization of aluminum applications in air conditioning, with several group standards being developed [3]. - Gree Electric's absence from the convention highlights its cautious stance on the aluminum replacement technology, contrasting with the collective commitment of other leading manufacturers [3][5]. Group 2: Gree Electric's Position - Gree Electric has reiterated its lack of plans to adopt aluminum in air conditioning until it can ensure 100% reliability, emphasizing the advantages of copper in terms of thermal conductivity and long-term reliability [5][6]. - The company has consistently expressed its concerns regarding the quality and performance of aluminum as a substitute for copper, with leadership stating that while aluminum can replace copper, it cannot guarantee the same quality [5][8]. Group 3: Technical and Economic Implications - The cost of copper can account for approximately 20% of the total cost of an air conditioner, while aluminum costs only about one-tenth of copper, suggesting significant potential for cost reduction if aluminum is successfully implemented [6]. - Despite the potential cost benefits, the physical properties of copper present challenges for manufacturers considering the switch to aluminum, leading to varied approaches among different brands [6]. - The push for aluminum replacement is also aligned with national strategies to reduce reliance on imported copper, enhancing supply chain stability [7]. Group 4: Market Dynamics and Future Considerations - The ongoing debate over aluminum versus copper has been fueled by rising copper prices, which have recently surpassed $10,000 per ton, prompting manufacturers to reconsider their material choices [8]. - Gree Electric's conservative approach may protect its brand reputation and customer trust, but it risks falling behind in a market increasingly driven by cost efficiency and material innovation [8].
