According to official data released by the National Bureau of Statistics of China, China’s aluminum sector delivered divergent production results in September 2026. These upstream and downstream metrics offer key insights for industrial buyers searching for dependable suppliers of aluminum plate, aluminum bar, aluminum tube and custom CNC machined aluminum components.

Primary aluminum output reached 3.908 million tonnes in September, rising 3.1% year on year. The cumulative production from January to September hit 35.026 million tonnes, marking a 3.8% year-on-year increase. Alumina, the essential feedstock for smelting, maintained solid growth. September alumina output stood at 8.40 million tonnes, up 5.5% compared with the same period last year, while the nine-month total reached 70.036 million tonnes, a 3.9% year-on-year gain. The steady expansion of primary aluminum and alumina reflects sustained smelter operation and sufficient upstream raw material support.

Downstream segments told a different story. China’s aluminum alloy production totalled 1.667 million tonnes in September, down 3.4% year on year, though the January to September cumulative volume of 14.042 million tonnes still posted a 2.1% year-on-year increase. Aluminum semi-finished product output also softened. September aluminum material output was 5.829 million tonnes, falling 2.4% year on year, and the nine-month cumulative figure of 49.079 million tonnes dropped by 1.6%. The decline in rolled and extruded aluminum products signals cautious production scheduling among fabricators, which may tighten availability for certain semi-finished aluminum profiles.

This mismatch between robust primary aluminum supply and weaker downstream semi-finished output creates procurement complexity. While smelting capacity remains stable, reduced finished aluminum fabrication can extend lead times and put pressure on spot prices for aluminum plate, bars and tubes. Manufacturers need a resilient supply chain partner to avoid disruption to their production schedules.
