OKUNO's strength in
nickel plating

Electroless nickel plating chemicals


  • High corrosion resistance
  • High adhesive property
  • High heat resistance
  • Wear-, abrasion resistant hard coating
  • Uniform thickness

Electroplating is deposited on the surface of metals when electricity is applied to substrates. Electroless plating enables to obtain deposits on metal or ceramics from chemical reaction by immersing substrates into aqueous solutions.
Electroless nickel plating, which realizes high hardness, high corrosion resistance and uniform deposition, is widely used in automotive parts, electronic parts and precision equipment for the following reasons.


  • 01

    No influence by current density, uniform deposition on complex-shape materials

  • 02

    Can plate on non-conductive parts, ceramics, plastic and various metals

  • 03

    Can composite electroless nickel with phosphorus, boron, PTFE, SiC to improve hardness, abrasion resistance, solder wettability


Differences in deposits

The most widely used is electroless nickel bathes containing sodium hypophosphite as a reducing agent. High corrosion-, abrasion-resistance, high hardness and/or other unique properties can be obtained by changing film composition.
