Alcoa Develops New Aerospace Solutions
Alcoa has developed a new set of aluminum-based solutions for the aerospace market that will allow airframers to build lighter and lower-cost short-range airplanes at lower production risk than composite-intensive planes. The new solutions, which combine new alloys and advanced structural technologies, use Alcoa sheet, plate, forgings and hard-alloy extrusion products across aircraft structures, including wings and fuselage elements. Included in the new solutions portfolio are advanced alloys and third-generation aluminum lithium alloys that result in up to 7% lower density in major structural applications. New improvements in aerodynamics for skin sheet developed by Alcoa reduce skin friction drag by up to 6%. In addition, new advanced structural technologies using forged, extruded and rolled products enable increased wing aspect ratio for improved fuel savings.
