Removing copper respectively to nickel




1999

Hi,

I need a chemical to remove 0.06 inches of copper respectively to nickel. If you are able to do it, if you can provide me the chemicals, or if you can tell me which chemicals to use, please contact me as soon as possible.

Thanks in advance

Best Regards

The best stripper is an alkaline cyanide solution. The resulting solution is a haz waste from both the cyanide and the copper content.

The alternate is a sulfuric acid with chromic acid. This is a haz waste because of the chrome, pH and copper content.

The best solution would probably be to find a shop to do your stripping, as haz waste generates a lot of paperwork, has safety considerations and is expensive to get rid of.

Another method that is more environmentally friendly is to use a hydrogen peroxide/sulfuric acid blend. The nickel should remain relatively unaffected. Our Laser EX product is great for that application.
