Gang:

Way back in the 60s, I think, there was a very thorough research article in
JIEE (Aust.) about RF skin conductivity of various practical metals. Oxygen
Free High Conductivity (OFHC) Copper won hands down. Until you heat it,
bend it, or look at it cross-eyed, that is. Silver plate is next best, but
only if it is hard Silver, not cosmetic Silver which is what you get at your
local plating shop. Hard Silver plate is difficult to come by, and uses
chemicals which I'm guessing have since been banned by EPA. In my day
(1960), hard Silver plate with a Rhodium flash was the most practical high
RF conductivity process available. Nowadays, who knows?
