Anodizing?

[ramius-ii]

Hi All!
Does any know of a place that will black anodize a 4 mm aluminum tube about 2.5" long? What is the most important is the inside of the tube for it is for optics.

Thanks in advance, Ed

Re: Anodizing?

Can be quite difficult to get anodizing done in small quantities. The type of aluminium affects the process, so a lot of companies don't want to know.

You could try a company that does chromium plating, many also offer anodizing. The other alternative is to have a go yourself.
