2074 Sheet – Next Generation Low Density AIRWARE® Sheet for Fuselage Applications

For many years, 2024 clad T3 aluminum sheets have been the standard material used for external fuselage skin sheets. In the 1990’s, 2524 clad T3 was developed delivering improved toughness and crack growth rate allowing lighter weight designs and allowing longer inspection intervals. Recently developed aircraft programs have adopted AIRWARE^® 2198 skins, capturing the benefits of increased performance combined with low density.

AIRWARE^® 2074 builds on the success of 2198, raising the bar on performance and manufacturability, enabling structural weight reductions, facilitating sustainability targets, and supporting use of both legacy and advanced fabrication techniques. The performance-weight balance of AIRWARE^® 2074 also supports utilization by the Advanced Air Mobility market for cabin structures.

The advantages and properties of AIRWARE^® 2074 compared to incumbent solutions will be presented, along with an update on its standardization path. An update on several other Constellium solutions will also be shared.
