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?

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.

Yes, BUT don't let that warning read with too much meaning, either.

The warning is there, just as the warning in experimentals. It reads that
this aircraft does not meet the qualifications of FAA certified aircraft, or
something like that. I'm sure most of you remember exactly what that says.

It should be noticed that while it has not been compared directly to the FAA
standards, there are many, many homebuilts that far exceed the FAA
standards. Some of the quality in homebuilts make certified aircraft look
like erector set airplanes, in comparison. g

Of course. As I pointed out to the Bradley Aerospace
(Bradley Aerobat) company rep, 6061 T6 has 95% of
the yield strength of 2024 T3, and better corrosion
resistance so that you can make back some of that
minor weight penalty by using less paint.

He keeps harping on how 6061 is not "aircraft aluminum".
So I asked him which standards organization sets the
standards for "aircraft aluminum". His response to that
was to delete my earlier article comparing 2024 to 6061.

As far as I can tell, "aircraft aluminum" is marketing hype
used to promote non-aviation products to a naive public.

As such, the term fits right in with Bradley Aerospace's
approach to marketing.

Remember "parachute luggage" from the 1970s? "Made from the same
material as Air Force parachutes."

Yep. Like "surgical steel".

I don't, or I wouldn't have bothered checking out in the plane. My comment was
only to point out that the OP might want to find a more bulletproof example to
prove his point.
