格力电器：暂无铝代铜计划 因铜材性能更可靠

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 Comparison - Despite the cost advantages of aluminum, it falls short in several critical parameters such as melting point, thermal conductivity, resistivity, corrosion resistance, and long-term reliability compared to copper [1] Group 3: Future Research and Development - The company is actively researching aluminum substitution technology and will continue to monitor industry trends [1]
