Removing chrome plate from copper

Recommended Posts

Chrome is also porous, the nickel under it seals it. The copper is used to smooth it out, the nickel over it seals it and the chrome adds the shine.

Cadmium plating was my first guess, Steve what did you think as you have probably run into more plated copper electrical components than the rest of us put together? (Tin and silver are also mentioned as possibilities when I looked into it right now)

I never have seen any chrome plating, Tin is more common, Cadmium is possible, no reason for nickel plating that I am aware of.   I have some buss bars that look more surface ground/polished
