CNC Machined Parts Electroless Nickel

The decisive advantage of chemical nickel is the completely uniform layer thickness distribution with low layer thickness tolerances, which makes it possible to coat even complexly shaped components with cavities or holes, covering every contour.

Electroless Nickel Plating services

- Electroless nickel deposition is a process for the co-deposition of nickel-phosphorus alloys without the need for an applied electric current.
- Instead of depositing ions from an applied current, this electroless nickel process chemically reduces nickel ions to the metal substrate in an electroless nickel solution. Therefore, the electroless nickel layer does not suffer from many of the problems associated with conventional electrolytic nickel, such as edge build-up and coating non-uniformity. The electroless nickel layer is very uniform, resistant to corrosion and corrosion, and has excellent lubricating properties.
