Aluminum Alloy, Extrusions 6.3Cu - 0.30Mn - 0.18Zr - 0.10V - 0.06Ti (2219-T8511) Solution Treated, Stress Relief Stretched, Straightened, and Precipitation Heat Treated
|Publication Date:||1 July 2020|
This specification covers an aluminum alloy in the form of extruded bars, rods, wire, profiles, and tubing up through 2.999 inches (76.2 mm) in diameter, least thickness, or wall thickness and 25 square inches (161 cm2) or less in cross-sectional area (see 8.6).
These extrusions have been used typically for structural parts requiring high strength up to 500 °F (260 °C), but usage is not limited to such applications. May be welded in the specified condition but properties are improved by reheat treatment after welding. Reheat treatment after welding, however, may reduce resistance to stress-corrosion cracking.
