Paint adhesion 6061 vs 7075
Paint adhesion 6061 vs 7075
(OP)
Would anyone know if paint just inherently adheres better to 7075 than 6061?
We've been doing some in-house comparisons. We use 6061, and our competitor uses 7075. And their primer seems to stick better. We are alodining the parts.
But before I dig too deeply, I'm just wondering if it's due to the base material itself, or if it's the paint/prep.

There are different grades of chem film. There is a grade that maximizes corrosion prevention at the expense of electrical impedance. Then there's a grade the minimizes impedance at the expense of poorer corrosion prevention. Then there's the ROHS versions.
I'm not sure if or how this affects performance as a substrate to paint though.

Soooooo.....I think that might have a little something to do with it. (gee, ya think?)
Thanks all......

The chemical films are used extensively as paint substrates. If the paint finish really mattered to me, I would avoid anodizing.
