Plating a Brass Part
Plating a Brass Part
(OP)
What is the best plating for going over a brass part? This is an old part that was originally cadmium plated. We can no longer use cad plating so I need to find a different type of plating. I was wondering if zinc plating would work? Or would electroless nickel plating work? There are also #8-32-2B threads running thru the part.

If you want it done then figure out why and ask a couple professionals what they recommend.
EN is easy. You can do it on your desk in a mazon jar. Good EN is much trickier.
I believe israelkk is referring to what I was taught to call "edge effect". Edges plate differently than flat surfaces.

EN on brass would definitely provide a beautiful finish, and you could mask any threaded holes if the plating thickness poses a problem. Zinc is cheap, but it is not pretty and provides little corrosion protection.

On parts I've seen it was sometimes because of the nominally 'self lubricating' properties of Cad.
I think PTFE impregnated electroless nickel plating was developed for this kind of application.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

You are correct, it should be 0.0002" (0.005 mm).
