Title
Aluminum Alloy, Extruded Bar, Rod, and Shapes 3.5Cu - 1.0Li - 0.40Mg - 0.35Mn - 0.45Ag - 0.12Ze (2050-T84) Solution Heat Treated, Stress Relieved, and Artificially Aged
Scope
This specification would cover an aluminum-lithium alloy in the extruded form. These extrusions are typically used for parts where low density, high mechanical properties and good stress-corrosion resistance are desired but is not limited in usage to such applications.
Rationale
Several customers are requesting that an AMS document be developed for this product form (Dassault, Lockheed Martin, Boeing...). Presentation was given at 2014 Spring AMS meeting about the product and approval was given by the committee.
