    History of Aluminum | The Aluminum Association

    Alloy development, begun in 1911, improved physical properties and opened new industrial fields. The Great Depression resulted in Works Progress Administration (WPA) projects that expanded hydroelectric generation capacity, which in turn increased production capacity of primary aluminum. During this time, the Aluminum Association was formed. The Association's first meeting was held in New ...
