Low phosphorus electroless nickel

Low phosphorus electroless nickel plating is a technical deposit composed of nickel (Ni) and phosphorus (1-3 wt% P). Like Kanigen® electroless nickel, it is also applied auto-catalytically by immersion in an aqueous environment.

The phosphorus content can be guaranteed with a tolerance of +/- 0.5 wt% P, and is measured in accordance with ISO 4527.

Our solutions


As deposited, the electroless nickel layer reaches a hardness of >750 HV0.1 (without thermal treatment).

Reduced Friction

Low-phosphorus electroless nickel reduces adhesive wear.

hardness without heat treatment


This type of deposit is generally used in applications where high hardness is required without the need for heat treatment.

Applications :

  • Valve fittings
  • Gearbox core
  • Connectors
  • Etc.

Processed Materials

The electroless nickel plating process makes it possible to treat a broad spectrum of materials used within the industry. Kanigen Group primarily treats carbon, alloyed and stainless steels, cast iron, aluminium and copper alloys, etc., along with other more special materials such as silver (Ag), INVAR, 17-4PH, etc.

In recent years, we have specialised in the processing of all grades of aluminium, including not only the 1000, 2000, 3000, 5000, 6000 and 7000 series, but also die-cast and injected aluminium, with the exception of ZAMAK alloys.

Treatments are carried out in barrels, rack plated or with dedicated fixtures.

crystalline structure

Corrosion Resistance

Due to its crystalline structure, the corrosion resistance of low phosphorus electroless nickel is lower than that of a Kanigen® electroless nickel layer.

Technical Properties

  • Hardness as deposited >750 HV0.1
  • Wear Resistance
  • Reduces friction
