有色金属周报（氧化铝与电解铝及铝合金）：美联储降息预期时点延至9、12月国内传统消费淡季特征渐显现-20250610

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The Fed's expected interest - rate cut has been postponed to September/December, and the characteristics of the traditional domestic consumption off - season are becoming more apparent [1] - For alumina, the production disturbance of bauxite in Guinea may push up prices and support production costs, but the potential resumption of new or overhauled alumina production capacity may lead to wide - range price fluctuations. For electrolytic aluminum, the easing of China - US tariffs may lead to an expected rush to export, but the traditional consumption off - season may weaken downstream demand, causing wide - range price fluctuations. For aluminum alloy, the decreasing domestic electrolytic aluminum inventory and increasing aluminum alloy inventory may cause the price difference between electrolytic aluminum and aluminum alloy to first strengthen and then weaken [3][5][7] 3. Summary by Related Catalogs Alumina - Supply - side factors: In China, Shanxi and Henan mines have not fully resumed production, and there are production disturbances in Guinea and Guangxi. However, new alumina production capacities in Shandong, Guangxi, and Shanxi are being put into operation or under construction, which may increase domestic production in June. Overseas, projects like Nanshan Aluminum's Indonesian project may increase production, and the opening of the import window may increase imports [3][26][31] - Cost and price: The daily average full production cost of Chinese alumina is about 2,880 yuan/ton. Alumina prices may fluctuate widely, and investors are advised to wait and watch, paying attention to the support level around 2,600 - 2,800 and the pressure level around 3,300 - 3,500 [3][23] - Inventory situation: The inventory in China's ports has increased, while the inventory in SHFE warehouses has decreased [14] Electrolytic Aluminum - Supply - side factors: Domestic production capacity such as Luoyang Yichuan Yugang Longquan Aluminum's transfer project and Inner Mongolia Huomei Hongjun Aluminum's project may increase production in June. Overseas, production changes in factories like Nanshan Aluminum's Indonesian project and New Zealand's Tiwai Point may affect imports [4][56] - Cost and price: The theoretical weighted average full cost of domestic electrolytic aluminum is about 17,200 yuan/ton. The price may fluctuate widely, and investors are advised to wait and watch, paying attention to the support and pressure levels of SHFE aluminum and LME aluminum [5] - Inventory situation: The social inventory of domestic electrolytic aluminum and aluminum rods has decreased, while the inventory in the bonded area has increased [40][43] Aluminum Alloy - Supply - side factors: The production of domestic scrap aluminum may decrease in June. The production of primary and secondary aluminum alloys may also decrease. The expansion project of Yichiu Resources is gradually releasing production capacity, increasing the operating rate of secondary aluminum alloy production [7] - Cost and profit: The daily full production cost of primary aluminum alloy is 20,060 yuan/ton, and that of secondary aluminum alloy ADC12 is 20,080 yuan/ton with negative profit [7] - Inventory and price difference: The social inventory of electrolytic aluminum is decreasing, while the inventory of aluminum alloy is increasing. The price difference between electrolytic aluminum and aluminum alloy may first strengthen and then weaken, and investors are advised to pay attention to short - term, light - position, low - buying arbitrage opportunities [7]
