It's just below Beer Can Quality, but I doubt anyone will push that
term.

I haven't heard of Duralumin in quite a while.

"aircraft quality" aluminum is aluminum that can be traced to the
producing mill and has a paper trail to assure it is what it says it
is. Can be any of several different series including 6061, depending
where it is being used on the plane.
