Alcoa is a vertically integrated aluminum company whose operations include bauxite mining, alumina refining, and manufacturing primary aluminum. It is the world's largest bauxite miner and alumina refiner by production volume, and the eighth-largest aluminum producer. Profits are closely tied to prevailing commodity prices along the aluminum supply chain.Alcoa was the first mass producer of aluminum, launching the world-changing Hall-Heroult smelting process in the 1880s, making aluminum affordable. It listed as a public company in 1925. In 2016, Alcoa spun off its automotive and aerospace metal parts segment to focus on mining, smelting, and refining. It bought the 40% unowned balance of AWAC in mid-2024, meaning refining assets are now predominantly wholly owned, as with smelting.
