Plating on copper


I want to protect a copper component surface by plating process. At the same time the plating should be of thermally very good conductor. Some people suggested tin or cadmium. Is there any other plating which gives good corrosion protection and thermal conductivity on copper.

Tin, Cad and electroless nickel all fit the stated need. For thermal conductivity, the plate layer is so thin that any metal would do quite nice. Not so with paints. Decision would be how much corrosion protection does it need and what other metal does it come in contact with.
