Alcoa Reports Alumina Production Decline, Aluminum Output Growth

Alcoa's alumina production fell 8% annually, primarily due to the full curtailment of the Kwinana refinery, completed in June 2024. In contrast, aluminum production increased by 5%, driven by the restart of capacity at the Warrick smelter and continued progress at the Alumar smelter.

For 2025, Alcoa projects alumina production between 9.5 and 9.7 million metric tons, reflecting a decline from 2024 due to the Kwinana refinery curtailment. Alumina shipments are expected to remain steady at 13.1 to 13.3 million metric tons, with the difference between production and shipments covered by trading volumes and externally sourced alumina.

Alcoa forecasts 2025 aluminum shipments to range between 2.6 and 2.8 million metric tons, while aluminum production is expected to rise to 2.3 to 2.5 million metric tons, supported by smelter restarts.
