Ormet Corporation is a major producer of primary aluminum in the US, and its operations ran the gamut of aluminum production. In addition to refining alumina, the company, through its Primary Aluminum unit, manufactures aluminum ingot, billet (pressed bars), sheet, foil, and other products for the fabrication, extrusion, and conversion markets. Its aluminum smelter in Ohio has the capacity to produce 270,000 tons of aluminum per year. Its former alumina refinery in Burnside, Louisiana (sold in 2013), could produce more than 500,000 tons of smelter-grade alumina per year. Ormet filed for bankruptcy in 2013.
