Sulphamate Nickel Grain Refiner
Is there a grain refiner for nickel sulfamate solution?

Sure, Veronica ... although the suppliers tend to call the additive for sulphamate nickel "hardener" rather than grain refiner. See if that term gets you rolling. Good luck.

Another way to reduce grain size is to use a pulse plating or periodic reverse type of rectifier.

Hi, there is a Pulse Reverse NickelChloride which gives finer grains than Sulphamate Nickel. Bath composition is cheaper than Sulphamate, no additives needed.
