For coating / anodizing properties, in a scale from 1(best) to 6 (worst) 6082 averages with 3.
Good alloys are 5005/5754/6005/6060 ranging from 2 to 1.
Question is not about what alloy but from where.
It has to be extremely clean, homogenous, well cast and rolled.
No problem with the mentioned Nasa grade alloys, but but alloys well suited for anodizing have not to meet special physical demands. So quality varies...like with transistors

Geez Loueeze.
6061-T6. Get it from McMaster-Car or Online Metals if there's no equivalent in Germany.
Your REAL worry should be who does the finishing and anodzing. ESPECIALLY if you're trying to go with anything other than black or clear (looks like you're wanting to do something in "gold").

6061 is 3, like 6082. Not very well suited for decorative anodizing.
I've seen thousands of anodized parts made from 6061-T6. The only problems were flaws in the material, or the person doing the anodizing. Cosmetically, it anodizes just fine.

Yup. Same here. What's most difficult is finding a finisher/anodizer who won't screw it up.

Correct!
As I wrote in Reply #12, some of the anodizers I met so far are not very ambitious -
so If something happens, I do not want to argue about the alloy chosen (even though I will do tests before.)
This is why I look for EQ=1 Grades (best for decorative anodizing)
One Aluminium supplier - he was proposed by an anodizer - told me to use 5083. It is also grade 3 but a variant called Alplan is grade 2.
I will take this as a last choice if I do not find something better.
I really wonder what alloy is used by Apple for their gear.
It has to be thin, durable, easy to mill - and still fast to anodize. It also has a very faint bronze cast, like it was hardcoated...
