Title
Aluminum Alloy, Extrusion, 2.7Cu - 1.8Li - 0.7Zn - 0.3Mn - 0.3Mg - 0.08Zr (2099-T81), Solution Heat Treated, Stress Relieved by Stretching 1 to 3% and Aged
Scope
This specification covers an aluminum alloy in the form of extruded bars, rods, and profiles (shapes) produced with cross sectional area of 22.5 square inches (145 cm^2) maximum and a circumscribing circle diameter (circle size) of 17.4 inches (44.2 cm) maximum.
Rationale
AMS4459A results from a Limited Scope Ballot to clarify requirements for fracture toughness testing (3.4.2).
