Nickel

Au

 

Nickel is one of the most widely used metals in plating due to its good technical and decorative properties. It is magnetic and highly resistant to alkalinic solutions and often used as a layer between other metals, such as copper and gold.

 

 

We offer the following types of nickel plating:

Bright nickel:

  • An external power source is used in the plating process (electrolytic plating)
  • Gives the component a beautiful, bright surface
  • Commonly used as an intermediate plating
  • Typical layer thickness is 2-20 µm

 

Semi-bright nickel

  • An electrolytic plating
  • A semi-bright, greyish metal coating
  • Less tension and better corrosion resistance than bright nickel
  • Softer than bright nickel

A duplex plating

  • A considerably higher corrosion resistance can be created by combining semi-bright and bright nickel. We use this plating for components destined for demanding conditions.

Chemical nickel (autocatalytic nickel)

  • Plating is done without an external power source (chemical plating)
  • Chemical nickel has better throwing power than electrolytic nickel, offering a more even surface distribution
  • From the chemical nickel we use, 8-10% phosphorus coprecipitates on the plated component
  • The phosphorus improves the nickel’s corrosion resistance in comparison to electrolytic nickels, which nevertheless conducts electricity better

Heat treatment of chemical nickel

  • Increases hardness and resistance to wear
  • Eliminates hydrogen embrittlement
  • Improves the platings adhesion
