SMM June 30th News: According to SMM statistics, domestic primary aluminum production in June 2025 (30 days) increased by 1.57% YoY and decreased by 3.23% MoM. In June, the operating capacity of domestic primary aluminum saw a slight MoM fluctuation. SMM learned that at month-end, the second-phase replacement of primary aluminum production in Shandong-Yunnan began, requiring the original plant to cut production for capacity replacement and pass acceptance inspections before restarting the new plant. In June, the proportion of liquid aluminum in domestic aluminum smelters continued to rise, with the industry's proportion of liquid aluminum increasing by 0.1 percentage points MoM to 75.8% this month. The increase was smaller than expected at the beginning of the month, mainly due to the high inventory of downstream alloys, with some regional aluminum plants increasing casting ingot production. It is expected that the proportion of liquid aluminum will show a pullback trend in July. Based on SMM's data on the proportion of liquid aluminum, the domestic primary aluminum casting ingot volume in June decreased by 12.77% YoY to approximately 872,500 mt.
