Large capacity smelter in U.S. and billet supplier

At our Mt. Holly aluminum smelter, we have the capacity to produce approximately 230,000 tonnes of aluminum each year. Mt. Holly is the youngest smelter in the United States.

Meeting Customers’ needs

Our smelter is equipped with advanced casting equipment that allows us to transform molten aluminum into standard-grade ingot, sow, extrusion billet, and other value-added primary aluminum products.

These value-added products are sold at a premium compared to standard-grade aluminum, reflecting their quality and versatility.
