格力电器称暂无铝代铜计划，铜材性能更可靠

Core Viewpoint - Gree Electric Appliances has no plans to replace copper with aluminum in its air conditioning products due to the superior performance and reliability of copper as a core material [1] Group 1: Material Comparison - Copper accounts for approximately 20% of the cost of air conditioners [1] - While aluminum costs about 1/12 of copper, its performance in terms of melting point, thermal conductivity, resistivity, corrosion resistance, and long-term reliability is significantly inferior to that of copper [1] Group 2: Future Plans - The company is focusing on research related to aluminum substitution technology and will continue to monitor industry trends [1]
