Aluminum products continue to make improvements to reduce weight of aerospace structures. With the increase and volatility of the price of crude oil and the need to reduce CO2 emissions, new Aluminum-base products are needed to enable cost effective structural weight savings of aircraft components. In this presentation, the latest plate, sheet, extruded and forged products from Alcoa for the aerospace industry are presented. The performance of several plate and extruded new products available for upper wing, lower wing and fuselage applications is discussed. Progress developing new alloys with and without Li additions is reviewed. Metrics indicating potential weight savings are presented.
The benefits of unitization/part reduction using new "large" 7085 and 2040 forgings from Alcoa Cleveland are discussed. It is concluded that advanced aluminum products continue to enable OEMs to reduce weight and cost of modern aircrafts.
