The aluminium lithium alloys 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, sheet and plate applications across aircraft structures, including wings and fuselage elements. The expansions follow discussions with air-framers subsequent to the launch of the alloys last year.
“The demand we are seeing for aluminium lithium is an excellent example of the Alcoa Technical Advantage in action and is the result of our continued leadership in aerospace alloy development across our Alcoa aerospace businesses,” says Eric Roegner, President of Alcoa Forged and Extruded Products.
“When completed, our aluminium lithium supply chain will be the premier operation in the world, capable of making the widest breadth of products in the most efficient manner – there will be nothing like it anywhere.”
