Anodize Aluminum 6061

Anodize Aluminum 6061

Anodize Aluminum 6061

(OP)
Hi, may I ask if anodizing Al6061 would make it non-conductive too?

RE: Anodize Aluminum 6061

(OP)
Thanks IRstuff.

Yeah. I am concerned it is thin and whether it can survive during vibration... it sounds like I need to get some experimental data?

RE: Anodize Aluminum 6061

Anodize is mainly a cosmetic treatment with a side effect of corrosion protection.

If you need electrical insulation then use an insulator.

RE: Anodize Aluminum 6061

Anodize is also a fatigue crack initiation source. It forms an irregular, rigid, oxide crystal on the surface of a soft metal. Good for abrasion resistance; not so good if the part flexes.

Thanks MinJulep and 3DDave!

@MintJulep, the part needs to be insulated is also structural part... wonder what other metal material can be used other than plastic?

RE: Anodize Aluminum 6061

This question begs 'a reason WHY' are You considering anodize of 6061... when conversion coatings may do the trick.

OH,BTW what temper 6061??? -T4 or -T6... and 'how thin'? Is it to be welded?

For electrical use exclusively in a very controlled environment?

Etc. The quality of our answers = quality of the question/parameters.

Hi WKTaylor,

My bad. The temper is T6.No welded joint and all screw and nut in a space environment.

RE: Anodize Aluminum 6061

It sounds like You might be designing a micro/small-sat?

I love spaceflight/spacecraft/satellite design... even though my bread-n-butter has been MIL! Materials in space are at a whole different level than earth-bound aircraft.

The NASA LDEF experiment used anodized 6061-T? for experiment trays... so it got +5.5 years on-orbit exposure. Awhile back I got a copy of the following document that might be very useful.

LDEF Materials Results for Spacecraft Applications https://ntrs.nasa.gov/api/citations/19940026507/do...

There are others, related to real-world [out-of-this-world] findings... do some digging.
