Alcoa’s new aluminum lithium alloys provide the best strength-to-weight performance in Alcoa’s aerospace alloy portfolio combined with better stiffness, damage tolerance, and corrosion resistance. The alloys are used in extrusions, forgings, sheet and plate applications across aircraft structures, including airplane wings and fuselage components. The expansions follow discussions with airframers subsequent to the launch of the alloys.
“We introduced our third-generation aluminum lithium alloys at the last Paris Air Show and demonstrated their potential to increase fuel efficiency, reduce inspection intervals, improve passenger comfort and lower capital costs for aerospace manufacturers,” said Mark Vrablec, President of Alcoa Aerospace, Transportation and Industrial Rolled Products. “The response was phenomenal. In fact, the response indicated demand that exceeded our production capacity at the time, so we launched initiatives to expand our aluminum lithium operations at three locations around the world (latest announcemenet). The initiative also provided us with the opportunity to increase our aerospace recycling capability for customers to benchmark status in the industry,” Vrablec added.
