Data from the International Aluminum Institute (IAI) shows that global primary aluminum production reached 6.227 million tons in March 2025, compared with 6.089 million tons in the same period last year, and the revised figure for the previous month was 5.66 million tons. China’s primary aluminum production is expected to be 3.729 million tons in March, with the revised figure for the previous month being 3.399 million tons.

The increase in global primary aluminum production may be influenced by the following factors:

1. Demand growth: Rising demand in industries such as construction, transportation (e.g., new energy vehicles), and packaging has driven production expansion.

2. Capacity release: Commissioning of new smelting capacity or improved utilization of existing capacity (e.g., resumption or expansion of production in China).

3. Changes in energy costs: A decline in electricity costs (aluminum production is energy-intensive) or the popularization of renewable energy has reduced production costs and stimulated output.

4. Price-driven factors: Higher primary aluminum prices have improved corporate profits, prompting manufacturers to increase production.

5. Policy factors: Carbon neutrality policies in various countries have promoted the green transformation of the aluminum industry, or supported capacity upgrades through subsidies and other means.

6. Inventory cycles: At low inventory levels, companies may increase production to replenish stocks.

7. Geopolitical factors: Supply chains in major producing countries (such as China, India, and Russia) have remained stable without being significantly impacted by major events.
