Aluminum Alloy, Extrusions 6.2Zn - 2.3Cu - 2.2Mg - 0.12Zr (7050-T76511) Solution Heat Treated, Stress Relieved, Straightened, and Overaged (Composition similar to UNS A97050)
This specification covers an aluminum alloy in the form of extruded bars, rods, wire, profiles, and tubing up to 5.000 inches, incl (127.00 mm, incl) in nominal diameter or least thickness (see 8.4).
These products have been used typically for structural applications requiring high tensile properties and good exfoliation corrosion resistance, but usage is not limited to such applications.
Rationale: AMS4340H results from a Five-Year Review and update of this specification. This standard is being reviewed as part of the SAE Five-Year Review policy. The committee will look at possible changes to ordering information and other potential updates throughout the standard.
