Advanced Aluminum Lithium Alloys


Advanced aluminum alloys are being used by NASA in the Ares 1 rocket. Breakthrough aluminum-lithium alloy technology continues to be developed at the Alcoa Technical Center in Pittsburgh to support projects such as the Ares program, along with first-of-a-kind manufacturing practices to meet the challenge of turning aluminum-lithium ingots into high performance plate products.

Aluminum-lithium ingots are cast at Alcoa Technical Center before being shipped to Alcoa’s Davenport Works in Iowa, where they are rolled into plate. Alcoa’s Davenport Works is the only supplier certified by NASA to provide the light gauge, high quality plate for the Ares 1 crew launch vehicle. In supplying plate products to NASA since 2008, Alcoa’s Technical Center and Davenport Works facilities have demonstrated both the capability and flexibility needed for NASA to meet its program goals.

Alcoa aluminum has been used in the space program since its inception.
