Core Viewpoint - The air conditioning industry is moving towards the use of aluminum alloy heat exchangers instead of copper due to rising copper prices and the high dependency on copper imports in China [1][3]. Group 1: Industry Trends - The 2025 China Home Appliance Technology Conference saw major companies like Gree, Xiaomi, and others announce the "Production Line Construction Specifications for Aluminum Tube Fin Heat Exchangers for Room Air Conditioners" [2][3]. - The air conditioning sector consumed approximately 1.723 million tons of copper in 2023, accounting for 10.7% of China's total copper consumption [3]. Group 2: Collaborative Efforts - A collaborative effort involving major air conditioning companies and academic institutions has led to the establishment of standards for aluminum heat exchangers, with further discussions planned for January [2][3]. - Companies including Xiaomi, Haier, and Midea have signed a self-regulatory agreement to promote aluminum heat exchangers and avoid negative competition among peers [4]. Group 3: Market Implications - The shift to aluminum heat exchangers is expected to lower air conditioning prices in the future, although copper heat exchangers may still be marketed as a premium option [4].
