格力电器：重视铝代铜技术研究，暂时没有铝代铜计划

Core Viewpoint - Gree Electric Appliances emphasizes that copper is a core raw material for air conditioners, accounting for approximately 20% of the total cost, and currently has no plans to replace copper with aluminum due to performance and reliability concerns [1] Group 1: Material Cost Analysis - Copper constitutes about 20% of the air conditioning cost, while aluminum costs approximately 1/12 of copper [1] - The price of aluminum is around 1/4 that of copper, and its density is about 1/3 of copper [1] Group 2: Performance and Reliability Concerns - Significant differences exist between copper and aluminum in terms of melting point, thermal conductivity, resistivity, corrosion resistance, and long-term reliability [1] - The company is currently not considering aluminum as a substitute for copper due to these performance and quality issues [1] Group 3: Research and Industry Monitoring - The company is committed to researching aluminum substitution technology and is continuously monitoring industry trends [1]
