Nothing stopping you using it in an airplane if you select an appropriate
size to account for its lower strength. I have used it in some modifications
to a restricted category aircraft. Just be aware that you cannot by 6063 to
an accepted aeronautical spec such as QQ_A Fed Spec etc so you might want to
allow an extra margin of safety to account for the commercial nature of the
material.

Can anyone tell me what the difference is between 6061 T6 and 2024 T3
and 6063 T5 is?

Bottom line: DON'T do it! Real, aircraft grade aluminum is not all that
expensive -- just check the Airparts catalog or their ad in Sport
Aviation. 2024-T3 is the standard aircraft structural aluminum, and
substituting a lesser grade only adds weight and can reduce safety in
structural applications.
