Copper Cyanide plating solution



(-----) 2007

We operate a copper cyanide plating bath here.
It consists of Copper Cyanide, Rochelle Salts, "free Sodium Cyanide", and Sodium carbonate.
It doesn't appear to be made up to any particular specification.
Can anyone recommend a typical bath makeup, giving a range of component concentrations?
Does this conform to any particular spec?
The copper plate is used as a mask for heat treatment of steel parts.
Thanks,
Mike Channing

I would start with whichever printed formulation from the Electroplating Engineering Handbook or Metal Finishing Guidebook comes closest to your current analysis, Mike.
