Thought of as the "aircraft alloy" because of its strength, 2024 has only fair corrosion resistance but good machinability. Lends itself only to resistance welding as a hot joining process and is not recommended for brazing or soldering. In the annealed state, 2024 has good workeability but is only fair to poor in tempers. Typical end uses are aircraft skins and cowls and truck and aircraft structurals.
