Core Insights - The air conditioning industry is undergoing a significant transformation with major brands like Haier, Midea, Hisense, TCL, Aux, and Xiaomi establishing a standard for replacing copper with aluminum in core components [1][5]. Industry Overview - Traditionally, copper has been the primary metal used in air conditioning systems due to its excellent thermal conductivity and corrosion resistance [3]. - The rising copper prices, which have increased by 35% this year and surpassed $12,000 per ton, pose a significant cost pressure on the air conditioning industry, especially since 80% of the copper used in China is imported [5]. Cost and Supply Chain Implications - The shift to aluminum is seen as a strategy to reduce costs and mitigate supply chain risks associated with heavy reliance on imported copper [5][7]. - Aluminum is significantly cheaper than copper, and China produces 60% of the world's electrolytic aluminum, ensuring a stable supply [7]. Competitive Landscape - Notably, Gree, a major player in the air conditioning market, has opted not to participate in the aluminum standard due to concerns about the durability and stability of aluminum compared to copper [7]. - This decision raises questions about consumer preferences, as brands using aluminum may offer lower prices while Gree maintains higher prices with copper, potentially affecting market dynamics [9].

Core Viewpoint - The air conditioning industry has reached a rare consensus on the "aluminum instead of copper" self-discipline convention, with 19 companies including Haier, Midea, Hisense, and Xiaomi participating in promoting this technological transformation [1][3]. Group 1: Industry Consensus and Reactions - The self-discipline convention emphasizes the prohibition of malicious attacks and encourages scientific promotion of aluminum heat exchanger air conditioners [3]. - Gree, although involved in the revision of national standards for aluminum instead of copper, did not join the self-discipline convention, stating that it currently has no plans to adopt aluminum due to concerns over performance and reliability [3][4]. - Gree's Vice President previously indicated that the company would not pursue aluminum until performance and quality could be guaranteed [4]. Group 2: Technical and Economic Considerations - The technical feasibility of aluminum replacing copper has significantly improved through structural optimization and process improvements, despite aluminum's thermal conductivity being only 60% that of copper [6]. - The cost advantage of aluminum is substantial, with copper prices reaching 92,000 yuan per ton compared to aluminum at 22,000 yuan per ton, making aluminum four times cheaper [7][8]. - The use of aluminum could reduce the cost of materials for a single air conditioner from approximately 600 yuan (copper) to 140 yuan (aluminum), potentially enhancing price competitiveness for manufacturers [8]. Group 3: Environmental and Strategic Implications - The shift towards aluminum is supported by national strategies, as the Ministry of Industry and Information Technology has expressed support for aluminum instead of copper, aligning with resource security and carbon reduction goals [7]. - Aluminum's production has a lower carbon footprint, with a 50% reduction in direct carbon emissions and a recycling rate of over 95% [6][7]. - The air conditioning industry consumed 1.723 million tons of copper in 2023, accounting for 10.7% of the national copper consumption, highlighting the industry's reliance on imported copper resources [7].
