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.
