Is there any difference between 6061 aluminum and aircraft grade
aluminum for that purpose?

Is "aircraft grade" something like "industrial strength" or "heavy duty"?

It's thrown around pretty loosely these days, but the term originally
referred to the aluminum-copper alloys developed in Germany around WWI,
which were given the name Duralumin. They were similar to today's 2024. Then
other precipitation-hardening grades were developed, and the term today
usually refers to 2024, 7075, and maybe a couple of other grades in the
2000- and 7000 Series.

But it's become a marketing term, like "billet," so you can't count on it
referring to a particular grade anymore.
