While many of its aluminum products may be lightweight, Arconic (formerly Alcoa Inc.) is anything but. Its products include industrial gas turbine, oil and gas equipment, aerospace and automotive components, and sheet aluminum for beverage cans. Nonaluminum products include precision castings and aerospace and industrial fasteners. In 2016 Alcoa Inc. separated into two public companies, Arconic (a value-added company making high-end aluminum products) and an upstream company -- Alcoa Corp., one of the world's top producers of alumina (aluminum's principal ingredient from bauxite) and aluminum.
