盘面延续偏强，持续关注政策影响

1. Report Industry Investment Rating - The走势 rating for casting aluminum alloy is "oscillation" [1] 2. Core Views of the Report - The price of remelted aluminum alloy ingots oscillated last week. The closing price of AD2511 decreased by 0.3% week-on-week to 20,280 yuan/ton, and the selling price of Baotai Group's ADC12 remained flat at 20,300 yuan/ton. The production cost of Fubao's ADC12 decreased by 33.1 yuan/ton to 20,025 yuan/ton, and the profit narrowed to 125.3 yuan/ton [1][12]. - The scrap aluminum market remains tight in supply, with the weekly arrivals of scrap aluminum traders decreasing for several consecutive weeks. The supply of crushed primary aluminum is particularly tight, and the price difference between scrap and primary aluminum has significantly narrowed. Attention should be paid to the cancellation of tax rebates in Jiangxi, Anhui and other places. If the policy spreads, it may lead to aluminum enterprises lowering the purchase price of non - invoiced scrap aluminum, and the invoiced scrap aluminum and imported raw materials will be in high demand [2][15]. - On the supply side of ADC12, the operating rate of secondary aluminum plants has stabilized and rebounded due to the seasonal increase in demand, and the lifting of environmental protection restrictions in Hebei, Jiangxi and other places has also contributed to the increase. However, the subsequent operating rate is still restricted by factors such as unclear local tax refund policies, difficult scrap aluminum procurement and high raw material costs. On the demand side, as it enters the traditional peak season in September, downstream demand has shown a slight recovery, but the peak - season performance remains to be seen. Attention should be paid to the risk of a lackluster peak season [2][16]. - Considering the tight supply of scrap aluminum and the significant decline in the raw material inventory of some alloy ingot factories, the cost support is relatively strong. It is recommended to pay attention to the opportunity of going long on AD2511 at low prices. In terms of arbitrage, as the peak season for automobiles approaches, the direct impact on the demand for ADC12 is higher than that for A00. It is recommended to continuously pay attention to the arbitrage opportunity of going long on AD2511 and shorting AL2511 [3][17]. 3. Summary According to Relevant Catalogs 3.1. Scrap Aluminum Arrival Declining for Several Consecutive Weeks, Continuously Monitor the Implementation of Tax Rebate Cancellation Policy - Last week, the price of remelted aluminum alloy ingots oscillated. The closing price of AD2511 decreased by 0.3% week - on - week, and the selling price of Baotai Group's ADC12 remained flat. The price of scrap aluminum in Guangdong remained unchanged, while the FOB price of crushed primary aluminum from Malaysia increased by 15 US dollars/ton. The cost of ADC12 decreased slightly, and the profit narrowed [1][12][13]. - The scrap aluminum market is in short supply, with the arrivals of scrap aluminum traders decreasing for several consecutive weeks. The supply of crushed primary aluminum is extremely tight, and the price difference between scrap and primary aluminum has significantly narrowed. The price of scrap aluminum is expected to remain strong in the short term. Attention should be paid to the cancellation of tax rebates in Jiangxi, Anhui and other places [15]. 3.2. Recent Industry News Review - In August, the PMI of the aluminum processing industry was 53.3%, showing a positive signal of transition from the off - season to the peak season. Primary alloys maintained steady expansion, while secondary alloys were still below the boom - bust line [18]. - In July 2025, China's scrap aluminum imports increased by 18.68% year - on - year. Thailand and Japan were the top two suppliers [18]. - Four ministries and commissions jointly issued a notice to regulate the implementation of policies related to investment promotion, requiring the rectification of issues such as illegal fiscal rebates and subsidies [18]. - The US expanded the scope of a 50% tariff on steel and aluminum imports, including hundreds of derivative products in the tariff list [19]. 3.3. Monitoring of Key High - Frequency Data in the Industry Chain 3.3.1. Scrap Aluminum: Tight Arrivals, High Prices - The supply of scrap aluminum is tight, with the arrivals of scrap aluminum traders decreasing for several consecutive weeks. The price of scrap aluminum remains high, and the price difference between scrap and primary aluminum has significantly narrowed. The price of scrap aluminum is expected to remain strong in the short term due to the unclear tax rebate policy and resource scarcity [15]. 3.3.2. ADC12: Strong Prices, High Social Inventory - The price of casting aluminum alloy futures oscillated last week, with a decline of 0.3%. The spot selling price of Baotai remained at 20,300 yuan/ton, at a premium to the futures price. The price is expected to remain strong in the short term. The price difference between ADC12 and A00 has been narrowing [16]. - On the supply side, the operating rate of secondary aluminum plants has rebounded, but is still restricted by factors such as unclear tax refund policies, difficult scrap aluminum procurement and high raw material costs. On the demand side, as it enters the traditional peak season in September, downstream demand has shown a slight recovery, but the peak - season performance remains to be seen. The social inventory of aluminum alloy ingots has continued to increase, while the in - plant inventory has decreased [16]. 3.3.3. Downstream: Marginal Weakening of Semi - Steel Tire Production, Be Aware of the Risk of a Lackluster Peak Season - As it enters the traditional peak season in September, downstream demand for ADC12 has shown a slight recovery, but the high - frequency data of automobile production shows that the weekly operating rate of semi -/full - steel tires has weakened, and the automobile inventory warning index has increased. Attention should be paid to the risk of a lackluster peak season [2][16].
