Sulfamate nickel is the most widely used electrolytic nickel. It is often used as a final plating layer and also as an underplate for precious metals. Sulfamate nickel is a pure deposit that allows soldering and brazing during later assembly steps. It is normally a dull grey to dull silver color depending upon the finish of the plated part.

Sulfamate nickel provides the lowest hardness, lowest internal stress and highest ductility of all the nickel plating systems. The finish is dull; this is an engineering finish and not a decorative finish. Sulfamate nickel has excellent solderability and good corrosion resistance. The high ductility of sulfamate nickel makes this product an excellent candidate for applications where part flexure or deformation, such as crimping, will occur.

Send us a drawing or photo of your part, along with your dull nickel plating specifications, and we will get back to you usually within one business day with a quote.

All analytical and testing compliance is performed by the HPW in-house laboratory. Thickness and adhesion verification, solution analysis and hydrogen embrittlement relief are a sample of Nickel-plating specification requirements. Inspection and testing are completed and documented for assurance of compliance to all specification and customer requirements.
