Report Industry Investment Rating No information provided. Core View of the Report The report analyzes the current situation of the copper market, indicating that the short - term contradictions in electrolytic copper continue due to regional market delivery pressure. It is expected that copper prices will remain in a low - level oscillation range of 91,000 - 93,000 yuan/ton in the next one to two weeks, influenced by factors such as supply - side pressure, weak demand, and a neutral - to - weak macro sentiment [3][63]. Summary by Relevant Catalogs Copper Futures Market Data Change Analysis - The price of the SHFE main contract on December 15, 2025, was 92,280 yuan/ton, a decrease of 1.84% from December 12, showing a slight decline. The premium of premium copper increased from 10 yuan/ton on December 12 to 85 yuan/ton on December 15, strengthening the basis [1][58]. - On December 12, 2025, the LME copper positions increased by 3,298 lots to 348,144 lots, and the trading volume expanded, indicating increased market activity [1][59]. Industry Chain Supply - Demand and Inventory Change Analysis - **Supply Side**: The LME inventory increased to 42,226 tons on December 15, 2025, a 29.67% increase from December 9, indicating increased supply pressure. Recently, BMC Mining listed on the Australian Stock Exchange to advance the KZK project, and Fortescue acquired AltaCopper's Canariaco project, which may increase future copper supply [2][60]. - **Demand Side**: On December 15, 2025, downstream procurement was weak. The decline in copper prices but still high absolute prices suppressed demand. The acceleration of aluminum - replacing - copper industrialization by Huafeng Aluminum may replace some copper demand [2][61]. - **Inventory Side**: The LME inventory increased significantly, the COMEX inventory increased to 450,618 short tons on December 12, 2025, and the SHFE inventory slightly decreased to 165,875 tons on December 15, 2025. Overall, the global inventory level increased, reflecting a loose supply - demand situation [2][62]. Price Trend Judgment The driving factors include increased supply pressure from inventory accumulation and potential new projects on the supply side; suppressed demand from weak downstream procurement and the risk of aluminum replacement on the demand side; and a neutral - to - weak macro sentiment. It is expected that copper prices will remain in a low - level oscillation range of 91,000 - 93,000 yuan/ton in the next one to two weeks [3][63].

Core Viewpoint - The ongoing debate in the air conditioning industry about whether aluminum can replace copper has been reignited, with Gree's leader, Dong Mingzhu, firmly stating that Gree will not adopt aluminum in place of copper [1][5]. Industry Analysis - Dong Mingzhu maintains that while aluminum can technically replace copper, the critical issue lies in the current maturity of technology to support long-term and stable user scenarios [5][6]. - Copper has been the default choice in the industry due to its excellent thermal conductivity, corrosion resistance, and mature processing techniques, while aluminum offers advantages such as being lighter, cheaper, and more abundant, making it attractive for cost control and large-scale manufacturing [6][8]. - The industry is increasingly moving towards aluminum substitution, with many brands already using aluminum in mid-range products or non-core components, and some companies are exploring ways to enhance aluminum's reliability through various treatments and modifications [6][7]. Company Position - Gree's decision to retain copper in core systems is seen as a cautious approach, especially as most companies are seeking more cost-effective and efficient solutions [8][10]. - The distinction in Gree's approach lies in its different standards for assessing "usable" versus "long-term reliable use," emphasizing that material selection is a long-term risk management issue, particularly for high-frequency, long-cycle appliances like air conditioners [11][12]. - Dong Mingzhu's stance reflects a commitment to ensuring that aluminum does not replace copper until it meets equivalent technical conditions and guarantees [14][15]. Future Outlook - The debate over aluminum versus copper is not a binary issue; it represents a technology route that is being continuously validated, with different companies adopting varying strategies based on their priorities [15][17]. - The ultimate resolution of this "copper-aluminum war" will depend on time, large-scale applications, and real data from long-term usage, with Gree's approach focusing on user responsibility rather than merely cost and parameters [17].
