[SMM Cast Aluminum Alloy Morning Comment: Cast aluminum alloy social inventory maintains weak destocking pattern; spot prices fluctuate at highs in the short term] On Thursday, the SMM A00 aluminum price saw a slight correction of 20 yuan/mt to 21,730 yuan/mt, while the ADC12 price held steady at 21,650 yuan/mt. Aluminum prices fluctuated rangebound, and quotations in the secondary aluminum market remained generally stable. Currently, raw material supply is tight, and aluminum scrap traders show strong willingness to hold prices firm, providing support for secondary aluminum costs. However, aluminum price fluctuations have intensified downstream wait-and-see sentiment, with demand marginally weakening and market transactions performing sluggish. It is expected that ADC12 prices will continue to fluctuate at highs in the short term, with limited room for change on either side. Downside support comes from the rigid cost floor due to tight aluminum scrap supply, while upside pressure stems from marginally weakening demand and downstream wait-and-see sentiment triggered by aluminum price fluctuations. Subsequent attention should be paid to raw material circulation, regional environmental protection policies, and changes in downstream orders.

ADC12 prices are expected to continue fluctuating at highs in the short term, with limited room for change. Downside support comes from rigid cost underpinning due to tight aluminum scrap supply, while upside pressure stems from marginally weakening demand and downstream wait-and-see sentiment triggered by aluminum price volatility. Subsequent attention should focus on raw material circulation, regional environmental protection policies, and downstream order changes.
