Electroless nickel plating

What is Electroless Nickel Plating?

Electroless nickel plating (EN) is a layer of nickel-phosphorus alloy on a metal or plastic substrate, and has better ability of anti-wear, anti-friction and anti-corrosion compared with electroplated nickel. The phosphorus content ranged from 2% to 13% in EN can define below three types:

1.) Low phosphorus EN: 

Widely applied for CNC parts which required uniform thickness nickel plating inside as well as its outside.

2.) Medium phosphorus EN: 

Most seen in industrial, electronic applications or decorative purpose. The thicker electroless nickel plating, the brighter, vise versa.

3.) High phosphorus EN: 

Best corrosion resistance for CNC precision parts which required ability of against highly corrosive acidic environments. Best surface finish with minimize porosity and nearly pit-free.
