History of Alcoa

Founded: 1888
Founders: Charles Martin Hall, Alfred E. Hunt

The brand began with a laboratory discovery. Charles Martin Hall, a recent Oberlin graduate, found a practical electrolytic method to produce aluminum in 1886. With financier Alfred E. Hunt and backing from the Mellon family, he formed the Pittsburgh Reduction Company in 1888. Before the Hall process, aluminum cost more per pound than silver.

The company renamed itself the Aluminum Company of America in 1907, and the Alcoa shorthand stuck as the public name for the next century. Alcoa supplied the material for the Wright brothers' engine crankcase, dominated American aluminum through both world wars, and survived a landmark 1945 antitrust ruling that broke its monopoly position.

Through the late twentieth century Alcoa grew into a vertically integrated giant spanning mines, smelters, aerospace fasteners, packaging, and wheels. The 2000 Reynolds Metals acquisition for about $4.6 billion was the peak of that consolidation era. The 2008 financial crisis forced a rethink, and CEO Klaus Kleinfeld ultimately split the company in two on November 1, 2016. The upstream business kept the Alcoa Corporation name.

The modern Alcoa has refocused and reinvested. It bought out joint venture partner Alumina Limited in August 2024 to gain 100 percent of the AWAC alumina system, sold its stake in the Saudi Ma'aden joint venture in 2025, and in June 2026 agreed to acquire South32's aluminum value chain assets for $4.1 billion upfront. Production records were set at five smelters and one refinery during 2025 alone.
