ELECTROLESS
NICKEL
Electroless nickel plating is the process
of plating nickel using a chemical generation of charge, rather
than an external current supply. It has a high degree of uniformity,
allowing complex shapes to obtain an even build-up of plating.
Electroless Nickel can be classified by the following phosphorous
content.
High Phosphorous 10% or higher phosphorous
content
Medium Phosphorous 6-10% phosphorous content
Medium to Low 3-6% phosphorous content
Low Less than 3% phosphorous content
Features and Benefits:
- Uniform thickness
- Amorphous Structure — Less Porosity
- High Hardness and Wear Resistance
- Excellent Corrosion Resistance
- Magnetic Properties
- Coats Non-Conductors
