331314 Secondary Smelting and Alloying of Aluminum

This U.S. industry comprises establishments primarily engaged in (1) recovering aluminum and aluminum alloys from scrap and/or dross (i.e., secondary smelting) and making billet or ingot (except by rolling) and/or (2) manufacturing alloys, powder, paste, or flake from purchased aluminum.

Cross-References. Establishments primarily engaged in--

Making aluminum and/or aluminum alloys from alumina--are classified in U.S. Industry 331312, Primary Aluminum Production;
Refining alumina--are classified in U.S. Industry 331311, Alumina Refining;
Manufacturing aluminum sheet, plate, and foil from purchased aluminum or by recovering aluminum from scrap and flat rolling or continuous casting--are classified in U.S. Industry 331315, Aluminum Sheet, Plate, and Foil Manufacturing;
Manufacturing aluminum extruded products from purchased aluminum or by recovering aluminum from scrap and extruding--are classified in U.S. Industry 331316, Aluminum Extruded Product Manufacturing;
Manufacturing rolled ingot or billet from purchased aluminum or by recovering aluminum from scrap and rolling or drawing--are classified in U.S. Industry 331319, Other Aluminum Rolling and Drawing;
Sorting and breaking up scrap metal without also smelting or refining--are classified in Industry 423930, Recyclable Material Merchant Wholesalers; and
Operating facilities where commingled recyclable materials, such as paper, plastics, used beverage cans, and metals, are sorted into distinct categories without also smelting or refining--are classified in Industry 562920, Materials Recovery Facilities.
