I'm looking for a very fast method to strip Nickel or Cobalt away from Copper alloys. No use to recommend phosphoric acid, sulfuric acid or cyanide solutions, as the problem here is that the copper base will be heavily attacked. To have some additional information, the stripper should be able to remove 0.1 you of Nickel or Cobalt within a few seconds. Any suggestions, commercial electrolytes or already proven solutions in Reel-to-reel plating? Thanking everyone in advance.
