To no one in particular.... When I was designing switches we would get silver plating of copper to jump the heat conduction ability of contactor plates (to which the contact rivets were affixed). You could rate the same switch to a higher standard by plating heavier silver to it. Just a thought if someone is working where there is limited space. Who knows, a flash of silver might be less costly than larger copper. Ask you local plater.
There are also specific bus bar alloys of copper with a very small addition of silver (fractional %). Apparently this gives quite a jump up in conductivity.
