Brightener for nickel sulfamate solution


Q. Is there a brightener for high speed nickel sulfamate plating solution? or is there a way to get a brighter deposit by using lower current or something similar?

A. In a word, yes. There are several commercial formulations available; check out the vendors on this site.

A. Yes. Most bright nickel(sulfate type baths) will brighten the deposit of sulfamate. You do give up some of the physical properties of the sulfamate solution(ductility and stress). Maybe a standard Watts type bright nickel plating bath would be worth considering.
