How about black electroless nickel?

There is a gold chem film, so why not a black chem film? The gold chem film parts we get back are greenish or reddish, I would assume from a dye agent. The part should not heat up beyond what the Chem Film can handle. Basically I am looking for a way around the costs of masking, yet keeping the asthetics for my cutomer.

Why--Because it is not a dye, it is a reaction between the aluminum and chromic acid with the help of several promoters, accelerators, inhibitors and etc. The different colors are because of differences in formulation and operating conditions of time,concentration, temperature with a small effect from the surface finish and activation.

Electrically conductive black coatings are available in many forms. Try Acheson.
