We make portable consumer electronic products, and the battery contacts have been plated with hex chrome. With that eliminated in Europe by RoHS requirements we need a good substitute.
Trivalent chromium may have the same problems
Gold is too expensive.
Silver tarnishes.
Stainless steel works but is hard to form.
What other material can be plated on spring steel contacts that conducts well and resists corrosion at a price for consumer products?

I did work for N.A.S.A. and we had a 3000 Watt transmitter that at one time was on a ship and to reduce corrosion everything was plated with brass and then Gold. It was so thin that we had no corrosive problems and they said it wasn't that expensive.
