We believe that Hawesville has a competitive advantage as the largest producer of high purity aluminum in North America. Four of Hawesville’s five potlines are specially configured and operated to produce high purity primary aluminum. The average purity level of primary aluminum produced by these potlines is 99.9 percent, compared to standard-purity aluminum which is approximately 99.7 percent. High Purity primary aluminum is generally sold at a premium to standard-purity aluminum.
Aluminum from the Hawesville smelter supplies the electrical conductor, remelt ingot and High Purity ingot markets, as well as the defense and aerospace industries.
Our High Purity product also supports the United States’ national security efforts and is used in defense applications such as the F16, Airbus, Naval war vessels, 747 airplanes and the International Space Station.
