Non-cyanide Nickel Strippers


(1998)

I would like to know who makes non-cyanide nickel strippers.

Metalx [a finishing.com supporting advertiser] has a family of B9 strippers that are good. Depends what you are stripping it off of. Acid might do the trick and it might destroy the part. IE:, not enough information given.

Enthone Enstrip NP takes Ni off Cu like candy and I've never had Cu base metal attack, but it doesn't seem to have much staying power. The solution becomes spent quite easily. Realize that Enthone makes over 20 strippers all named Enstrip, so you must get the correct one to avoid base metal problems. Patclin Chemical Co. also has a line of killer strippers. So does Udylite.

Good Luck

If you are stripping from steel why don't you consider using an electrolytic strip based on sodium nitrate. These work well without any base metal attack. You have to have a fairly high current density , and there should be no brazing on your components. Welding can be attacked if C.D. is too low , or when the tank gets old.

For stripping nickel off cu, you might try a 50-50 mixture of nitric and Muriatic Acid [linked by editor to product info at Amazon]. It works reliably with tin on copper with no attack on the base metal. Caution must me exercised when using this mixture. For stripping nickel off aluminum, you might try a mixture of 6 gallons nitric, 2 gallons of water, and about a quart of muriatic acid. If you use to much muriatic it will attack the aluminum. Good Luck.
