Stripping Nickel-P Coating 

 

Dear Sir:

I am a research student for Nickel-P electroless plating. I want to strip the Nickel-P coating without damage the copper or Aluminum substrate. Is there any solution suitable for that? I have tried to strip the EN Nickel coating by 1:1 nitric acid, unfortunately, It seems that nitric acid is too strong for copper than the EN nickel. Finally, I find the Cu substrate, which is about 0.1-0.2 mm, is eroded by nitric acid through cross-side.

Editor's note: Metalx offers such a stripper.
