Electroless Nickel Plating
Electroless nickel is a hard, silver coloured coating comprised of nickel alloyed with between 4 and 14% phosphorus. It is deposited by immersion of parts in a solution of nickel salts and reducing agents at a temperature of 90°C. Although it has the appearance of an electroplated coating, the process is purely chemical, so that deposition is evenly distributed over the part, including internal and external corners.
We offer four types of electroless nickel plating options; Low phosphorous – hard, good corrosion protection that’s best for high temperature applications; Medium Phosphorous – the most common, bright and with relatively good corrosion and wear protection; Graded medium phosphorous – unique to Poeton giving exceptional corrosion protection; and High phosphorous – glass like structure with the best corrosion protection and non-magnetic.
For advanced electroless nickel plating see Apticote 400. For a non-stick nickel coating use Apticote 450, an electroless nickel/PTFE coating where the PTFE particles are co-deposited with the Nickel.

The tank sizes shown above are approximate sizes only. If you have a larger part then please contact us as we may still be able to help.
The medium phosphorous variety give a hardness of around 500-550Hv but can be significantly increased with heat treatment.
Nickel coatings provide a continuous barrier to prevent corrosion.
Typically applied at a uniform thickness of 25µm.
