BIGGUNDOCTOR Posted November 27, 2017 Share Posted November 27, 2017 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. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted November 27, 2017 Share Posted November 27, 2017 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) Quote Link to comment Share on other sites More sharing options...
BIGGUNDOCTOR Posted November 28, 2017 Share Posted November 28, 2017 A plating shop would be my first choice. They can deplate as well as plate items. Quote Link to comment Share on other sites More sharing options...

I have some buss bars that look more surface ground/polished Quote Link to comment Share on other sites More sharing options...
BIGGUNDOCTOR Posted December 3, 2017 Share Posted December 3, 2017 The shop that I worked at made electrical connectors, and many were nickel plated.. Quote Link to comment Share on other sites More sharing options...
