Quality Electroless Nickel Plating Services from Klein Plating Works

Klein Plating Works (KPW) offers industrial electroless nickel plating services in accordance to MIL-C-26074 or ASTM B733. KPW offers the electroless nickel binary alloys which consist of medium phosphorous, high phosphorous, and nickel-boron chemistries. Our electroless nickel is RoHS compliant.

Electroless nickel plating is a process of plating nickel by means of a chemical reduction rather than the use of external electrical DC current. This means that any active surface that comes into contact with the solution will be coated. The process is “autocatalytic” and will continue to plate over itself after the substrate is covered allowing for high plating thicknesses. The lack of current density issues means that electroless deposits are very uniform regardless of complex part geometries.

The benefits of electroless nickel plating include:

  • Uniform Deposits
  • Hardness
  • Great Abrasion/Wear Resistance
  • Less Porous
  • Corrosion and Chemical Resistance
  • Lubricity
  • Solderability
  • Magnetic Properties (High Phos. is non-magnetic)

The deposits of electroless nickel plated metals can contain various degrees of phosphorous or boron depending on the chemistry used which allows for unique properties and a variety of applications. The excellent corrosion/wear protection, hardness, electrical, and magnetic properties of electroless nickel plated metals allows for electroless nickel plating services to be frequently used in the electronics, aerospace, marine, and automotive industries.

The deposits have a hardness range from 450-700 Knoop. This can be increased with heat treating to 500-980 Knoop. Electroless nickel plating is more costly than electroplated nickel plating and is not always a substitute. Our specialized electroplating team provides electroless nickel plating using various methods including the barrel plating method and rack plating method.
