NIPHOS® 966 Nickel-Phosphorus Electrolyte as Alternative to Electroless Nickel

Alternative to electroless nickel

With NIPHOS® nickel-phosphorus alloy layers with high phosphorus content can be plated electrolytically in barrel-, rack- or reel-to-reel lines. Compared to electroless nickel layers containing a high phosphorus content, the electrolytic nickel-phosphorus layers are amorphous, diamagnetic and abrasion and corrosion resistant. The layers can be applied as intermediate layer (prior to e.g. tin, chromium or gold) or as final layer. In comparison to electroless nickel, electrolytic nickel-phosphorus electrolytes are operated at low temperatures.

Nickel-phosphorus electrolytes can be operated with soluble anodes (nickel), insoluble anodes (platinum plated or MMO) or a combination of both. The lifetime is almost unlimited and corresponds to the one of bright nickel electrolytes. NIPHOS® is insensible to contaminations with metallic particles. In contrary to electroless nickel it does not tend to random plating. Also the electrolytes are free from halides and contain, besides nickel, no other heavy metals such as lead or cadmium.
