Speaking of which, does anyone know what "aircraft quality" aluminum
actually is? As far as I know, there is no such designation. The stuff
I've been using in my ultralight is 6061-T6 but I don't think it's
called "aircraft quality". Just another marketing ploy.

Jim

My airplane is nearly all 6061-T6

But I think they usually want that to mean 2024-T3 with the shiny alclad
surface...

I think it just means one of the heat-treatable alloys to most people.
They aren't talking about quality, they're talking about grade. There's
no such official designation for aluminum as "aircraft quality." The shop
I worked in made many parts for experimental aircraft, for Forrestal
Research Center, and all they wanted was grade and the certs for the
aluminum.

That was my point, Ed. The marketers have used the term "aircraft
quality" to sell their crap. It has no real meaning but it sounds good.

All I can say is, what do you think the general public would make of it if
they said, "2024 T3 aluminum," or, if you want a higher grade, you can have
it in "your choice of 3003 or even 5052"? g

I think we can cut them some slack here. Most people wouldn't know what the
hell they were talking about, but "aircraft quality" comes closer to
explaining to the public what it is.
