U.S. billet supplier and growing scrap reprocessing capabilities

Century’s Sebree aluminum smelter has a production capacity of approximately 220,000 metric tonnes per year. The facility is 100-percent owned and operated through Century Aluminum.

Sebree is located in Henderson County, Kentucky, perfectly situated in the middle of the Midwestern market. It is an ideal location to conduct business as a large majority of the smelter’s customers are within a 600-mile region. Since it began operations in 1973, more than 10 billion pounds of aluminum have been created.

Our Sebree smelter employs approximately 625 workers within the tri-state region – it is one of the largest manufacturers in the area.

Carbon Facilities

  • This department creates carbon blocks in a newly installed baking system
  • Each block weights approximately 1,700 pounds each and are made, baked and then shipped to Potlines where they are put inside each pot to conduct electricity

Casthouse Facilties

  • All of the potlines’ molten metal is transported by a cruce truck to the Casting department. In Casting, employees turn the new aluminum into primary products: Examples include billet and low-profile sow
  • Cast billet resembles a 20-foot telephone pole, which is then heat treated and cut to customer specifications. Billet is shipped to extruders who apply pressure and heat to re-shape the billet into such things as air conditioning coils and window frames
  • Sow is shipped to various customers who re-melt it for blending and casting into various shapes

Power Supply

Sebree has a power supply arrangement which provides market-based power to the Sebree smelter. Under this arrangement the power companies purchase power on the open market and pass it through to Sebree at Midcontinent Independent System Operator (“MISO”) pricing plus transmission and other costs.
