Who is the largest aluminum foundry in the world?

While it’s difficult to definitively state which is the single largest aluminum foundry in the world due to the dynamic nature of the industry and varying metrics (such as production capacity, revenue, or market share), some of the largest aluminum producers and foundries globally include:

1. Alcoa (Aluminum Company of America) – One of the world’s largest producers of bauxite, alumina, and aluminum products.

2. Rio Tinto Alcan – A major global aluminum producer.

3. Norsk Hydro – A large Norwegian aluminum and renewable energy company.

4. Chalco (Aluminum Corporation of China) – One of the largest aluminum producers in China.

5. Emirates Global Aluminium – The largest industrial company in the United Arab Emirates outside of oil and gas.

6. Rusal – A Russian aluminum giant, one of the world’s major producers of aluminum and alumina.

7. Hindalco Industries – An Indian metals flagship company of the Aditya Birla Group.

These companies operate multiple foundries and production facilities worldwide. The largest single foundry would likely belong to one of these major producers, but specific facility information can change over time due to mergers, acquisitions, and capacity expansions.
