About Century Aluminum
Century Aluminum Company is a global producer of primary aluminum and operates aluminum reduction facilities, or "smelters," in the United States and Iceland.

Our smelters produce standard-grade and value-added primary aluminum products. Our current annual production capacity was approximately 770,000 tonnes per year ("tpy") as of December 31, 2025. We produced approximately 638,000 tonnes of primary aluminum in 2025.
