Electroless Nickel (EN) Plating

Using our over 30 years of experience in the coatings industry, we designed and built a superior Electroless Nickel Plating finishing line. Our state-of-the-art nickel plating line uses only ROHS and ELV compliant mid and high-phos chemistry, allowing us to produce high quality coatings with quick turn around.

What Does Electroless Nickel Plating (EN Plating) Mean?

Electroless nickel (EN) plating is an auto-catalytic reaction used to deposit a coating of nickel on a substrate such as metal or plastic. It provides wear resistance, hardness and corrosion protection of the substrate.

There are several advantages Electroless nickel plating has  over electroplating. Free from flux density and power supply issues, it provides an even deposit regardless of workpiece geometry.

Ferrous and non-ferrous surfaces of any geometry can  be plated using Electroless Nickel plating.

This electroless process greatly improves the object’s resistance to galling and leaves a predictable, uniform nickel coating on high-precision parts. Electroless nickel plating is often less porous than electroplated nickel and hard chrome, provides barrier protection to steel, and can also be applied with little or no compressive stress, thus making it gentle in application.

This process provides a wide range of thickness and volume of the plating on metallic surfaces, and can easily fill recesses or pits in the metal’s surface, resulting in a uniform surface finish. This allows for a wide variety of industrial parts to be plated.

Electroless plating has many industrial applications, from merely decorative to the prevention of corrosion and wear.


Electroless nickel-phosphorus is used when wear resistance, hardness and corrosion protection are required. Applications include oilfield valves, rotors, drive shafts, paper handling equipment, fuel rails, optical surfaces for diamond turning, door knobs, kitchen utensils, bathroom fixtures, electrical/mechanical tools and office equipment.

Due to the high hardness of the coating, it can be used to salvage worn parts. Coatings of 25 to 100 micrometers can be applied and machined back to the final dimensions. Its uniform deposition profile means it can be applied to complex components not readily suited to other hard-wearing coatings like hard chromium.
