Form:

This specification covers an aluminum alloy in the form of extruded bars, rods, wire, profiles, and tubing.

Application:

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.
