The US$90 million, 115,000 ft2 expansion will produce more than 20,000 metric tons of aluminium lithium and be capable of casting round and rectangular ingot for rolled, extruded and forged applications.

The newly patented aluminium  lithium alloys will allow airframers to build lighter and lower-cost airplanes versus composite alternatives. They can provide the best strength-to-weight performance in Alcoa’s aerospace alloy portfolio combined with better stiffness and corrosion resistance. The alloys are used in extrusions, forgings, and sheet and plate applications across aircraft structures, including airplane wings and fuselage elements.

“Our primary role as aerospace solution providers is to help the OEMs reduce fuel consumption per seat mile,” said Eric Roegner, President, Alcoa forgings and extrusions. “We have a long history working with aerospace customers to help new aircraft meet demanding new missions and provide optimum solutions for both the engine and airframe structure.”
