Hi,
The question is more or less as per the title : is there a painless way to blacken alluminium (6082) which doesn't involve the palaver associated with anodising (eg acid baths and electric currents). Ideal would be a solution of something innocuous that you can immerse the part in at room temperature and just leave for a while than take the part out and be done.
I know "paint" almost fits the description but the blacked areas need to be to a close tolerence which makes paint a bit non-ideal....
Thanks for any advice,
