Electroless nickel

Electroless nickel: process and advantages

The electroless separation of nickel-phosphorus alloys has a number of outstanding advantages and often meets requirements that cannot be achieved with other processes.

The application is recommended where parts must be provided with a high fitting accuracy and a absolutely uniform layer thickness.

High corrosion protection and wear resistance are also exceptional features of this coating.

Technical data

Suitable materials:

  • Steel and iron materials
  • Aluminium and aluminium alloys
  • Non-ferrous metals as copper, brass, bronze

Application techniques:

  • Rack application
  • Drum

Phosphorus content:

  • High, medium and low phosphorus content for special problem solutions

High corrosion resistance:

  • Vastly superior to galvanic nickel layers

High Hardness:

  • 450-650 HV (0,05) in deposition state
  • Approx. 1000 HV (0.05) after heat treatment

Products:

  • Novatec 710 EL Phos. Content 1-4%
  • Novatec 720 EL Phos. Content 6-9%
  • Novatec 730 EL Phos. Content 10-14%

Uniform layer thickness distribution due to good dimensional stability:

  • Also on geometrically complicated parts in drill holes and on the inside of hollow parts.

Possible applications
