Alcoa, American corporation founded in 1888 that, during the 20th century, grew to become a leading producer of aluminum. Originally called the Pittsburgh Reduction Company, it was renamed the Aluminum Company of America and became known as Alcoa, which was eventually adopted as the companyâs official name. In 2016 Alcoa was split into two independent corporations: one, which retained the Alcoa name, focuses on mining and aluminum processing, and the other, called Arconic, is a materials supplier for manufacturing and other industries. Both companiesâ headquarters are in Pittsburgh.
Pittsburgh Reduction Company was founded by a group of young men that included Charles Martin Hall, who in 1886 had been the first American to succeed in developing a commercially cheap method of smelting aluminumâby electrolysis. In 1891 the company began producing cast products (such as teakettles) and aluminum sheeting as well as raw aluminum, and in 1899 it acquired its first bauxite mining rights. By 1907, when it reincorporated as the Aluminum Company of America, it had numerous mines, alumina (aluminum oxide) plants, hydroelectric facilities, aluminum smelters and fabricating facilities, and the Alcoa Technical Center (in Pittsburgh) for laboratory research and development. Alcoa founded a company town in Tennessee, called Alcoa, that was incorporated in 1919.
In 1928 Alcoa created an independent company in Canada, Aluminium Limited, and transferred to it almost all of Alcoaâs holdings then outside the United States. In return, Alcoa received the common stock of Aluminium Limited. However, after years of legal action against Alcoa by the U.S. government on antitrust grounds, Alcoaâs stockholders were compelled to divest themselves of their stock in Aluminium Limited, though Alcoa was absolved of wrongdoing. (The Canadian company, which took the name Alcan, was purchased by the mining company Rio Tinto in 2007.) Among the foreign countries over which Alcoa had significant influence was Suriname, where the company operated from 1916 to 2015.
