Alloys for certified parts?

I have run across someone who insists that
6061 T6 is not "aircraft grade aluminum".

He claims that there are no certified parts made
from 6061. I find that hard to believe. Aren't there
certified aircraft with welded aluminum frames?

That is a pretty broad statement.

Parts are made from any materials that the manufacturer
desires/specifies. Wood, aluminum, brass, glass and anything in between.
That includes 6061 of all tempers.

That is kinda what I thought. I'd like to find some specific examples
of certified aircraft parts made from 6061. I took a gander at
Aircraft
Spruce's online catalog, but the search function isn't set up for
that.

I'm thinking that certified metal props will probably be 6061 too.

I think it will be quiet around here now. So long.

The Cessnas I work on every day have a lot of extruded angle
in them, and I bet much of it is 6061T6. Perhaps the spar caps are
2024T3 extrusions.

The LSA certified Zeniths are 6061-T6.

Aha!.

I see that Aircraft Manufacturing & Development Co. (AMD)
sells FAA certified SLSA Zodiacs.

Glad I could help. I have plenty of scrap 6061-T6 that you can have to tell
him to stick it up his A$$.

While I believe you are on the winning side in your argument about aircraft
materials, the Zodiac may not be the best example to prove your point. As an
LSA, tt is certified to an industry standard, not an FAA standard. I recently
checked out in one and it even has a "warning" in the cockpit to that effect.
