SAE AMS4413C-2023 - Aluminum Alloy, Plate 3.5Cu - 1.0Li - 0.40Mg - 0.35Mn - 0.45Ag - 0.12Zr (2050-T84) Solution Heat Treated, Stress Relieved, and Artificially Aged

Scope: This specification covers an aluminum-lithium alloy plate in thicknesses from 0.500 to 8.000 in. (12.70 to 203.20 mm), inclusive (see 8.5). The plate is generally used for parts requiring low density, high mechanical properties, and good resistance to stress corrosion cracking, but its use is not limited to such applications.
