氧化铝周报：少量检修开启，氧化铝有望止跌-20260126

1. Report's Industry Investment Rating - No information provided in the given content. 2. Core Viewpoints of the Report - Domestic partial alumina enterprises are conducting maintenance, and the news of production cuts at an Australian alumina plant helps the alumina price stop falling. However, overseas disturbance news has limited impact on current production, and there is still 6 million tons of new production capacity to be put into operation overseas this year, so the actual impact on the supply increase this year is limited. The current maintenance capacity in China cannot support the reversal of the supply - demand situation. It is expected that the price will stop falling, stabilize, and fluctuate in the short term, and the subsequent rebound of alumina still needs to see more production cuts [2][6]. 3. Summary According to the Table of Contents 3.1 Transaction Data - From January 14th to January 23rd, 2026, the alumina futures (active) dropped from 2800 yuan/ton to 2724 yuan/ton, a decrease of 76 yuan/ton; the domestic alumina spot decreased from 2681 yuan/ton to 2657 yuan/ton, a decrease of 24 yuan/ton; the spot premium decreased from 138 yuan/ton to 80 yuan/ton, a decrease of 58 yuan/ton. The Australian alumina FOB decreased from 309 US dollars/ton to 304 US dollars/ton, a decrease of 5 US dollars/ton; the import profit and loss increased from - 47.37 yuan/ton to - 22.79 yuan/ton, an increase of 24.6 yuan/ton. The exchange warehouse inventory decreased from 170,779 tons to 138,697 tons, a decrease of 32,082 tons, and the exchange factory warehouse remained at 0 tons [3]. 3.2 Market Review - The main alumina futures contract dropped 0.98% last week, closing at 2724 yuan/ton. The national weighted - average price of the spot market on Friday was 2657 yuan/ton, a decrease of 24 yuan/ton from the previous week. In terms of bauxite, some domestic northern mines had phased production cuts due to weather, while the southern supply was stable, and the domestic bauxite price remained stable. The arrival volume of Chinese bauxite on January 9th was 3.5409 million tons, a decrease of 501,400 tons from the previous week, with an overall abundant import and pressured prices. On the supply side, the total built - in production capacity of national metallurgical - grade alumina was 110.32 million tons/year, and the total operating production capacity was 87.12 million tons/year. The national weekly alumina operating rate decreased by 1.85 percentage points to 79.97% compared with the previous week, with domestic alumina plants operating at a high level. On the consumption side, electrolytic aluminum enterprises in Xinjiang and Inner Mongolia continued to release newly - put - into - operation production capacity, with an increase in operating production capacity compared with the previous week, and the theoretical demand for alumina increased slightly. In terms of inventory, the alumina futures warrant inventory was 139,000 tons last Friday, a decrease of 38,105 tons during the week, and the factory warehouse remained at 0 tons [4]. 3.3 Market Outlook - A gold mine in Siguiri Province, about 800 kilometers northeast of Conakry, the capital of Guinea, collapsed, causing at least 6 deaths. The incident occurred in the Doko area, which is a manual gold - mining area with no bauxite mines, and the straight - line distance to the nearest main bauxite - mining area is about 520 kilometers, having no impact on bauxite production and shipping for the time being. Imported bauxite is abundant with light trading, and prices are under pressure. Domestic bauxite remains in a tight situation with fluctuating prices. On the supply side, there have been small - scale maintenance in Shanxi, Henan, Guangxi and other places in China, and the operating production capacity has decreased compared with the previous period, but the operating production capacity after maintenance is still theoretically in excess. Rio Tinto Group said it will cut the output of its Yarwun alumina refinery in Australia by 40% starting from October 2026, involving a production capacity of 1.2 million tons. The production capacity of downstream electrolytic aluminum enterprises has increased slightly, and procurement still mainly follows long - term contracts. The alumina warrant inventory was 139,000 tons, a decrease of 38,105 tons during the week [2][6]. 3.4 Industry News - In December 2025, China imported 227,800 tons of alumina, a month - on - month decrease of 1.98% and a year - on - year increase of 1388.89%; exported 205,900 tons of alumina, a month - on - month increase of 22.56% and a year - on - year increase of 9.35%; the net import volume of alumina was 21,900 tons, a month - on - month decrease of 65.99% and a year - on - year decrease of 112.66%. From January to December 2025, the cumulative import was 1.1981 million tons, a year - on - year decrease of 15.62%; the cumulative export was 2.5492 million tons, a year - on - year increase of 42.76%; the cumulative net export volume of Chinese alumina was 1.3511 million tons, a year - on - year increase of 269.48%. The total import volume of Chinese bauxite in December was 14.67 million tons, a month - on - month decrease of 2.9% and a year - on - year decrease of 2.0%. As of December, the cumulative import volume this year reached 201.19 million tons, a year - on - year increase of 26.4%. The cumulative consumption of imported ore by Chinese alumina enterprises as of December was about 155.77 million tons, and the current imported bauxite market is in a state of oversupply. Two alumina enterprises in Guangxi started maintenance this weekend. Enterprise A plans to start roasting maintenance on January 24th, which is expected to end in 14 days, affecting about 40,000 tons of production during this period. Enterprise B plans to start roasting maintenance on January 25th, which is expected to end in 10 - 12 days, with a halved production during this period and a daily output reduced to about 2800 tons. A certain alumina enterprise in Henan stopped all roasting production lines for maintenance this morning and is currently only producing aluminum hydroxide. Before the shutdown, only one production line was in operation due to environmental control. It is expected that one production line will resume operation in about 10 days, and the downstream delivery will not be affected during the maintenance period [7]. 3.5 Related Charts - The report provides charts on alumina futures price trends, alumina spot prices, alumina spot premiums, alumina month - to - first - continuous spread, domestic bauxite prices, imported bauxite CIF, caustic soda prices, thermal coal prices, alumina exchange inventory, and alumina cost - profit [9][10][13][15][18][21][24].
