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

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


Not exactly. Certain grades of aluminum were developed from need of the
aircraft industry. They are, in general, very much stronger when heat
treated (or aged) than other grades of aluminum. 7075 is likely the
strongest (it rivals mild steel in tensile strength when aged to a T6, or
T651 condition, with 2024-T351 being quite good as well.

7075T? also considerably less ductal that 6061-T6...

If that matters in this application.
