Columbus used to sell a tubeset made from Al-Mg 5000 Alloy which did not need heat treatment. Seems to be discontinued these days though.

Strength in solid-solution strengthened aluminium alloys is a best mediocre and at worst dire. The welding process irreversibly destroys the only possible route to strengthening in the material - the dislocation pileup of cold work. There's no acceptable metallurgical reason for using such alloys in bike frames.

Aren't 7005 frames from the Orient typically not artificially aged?
