About Electroless Nickel

Electroless Nickel is an auto-catalytic plating process that deposits a thin, uniform Nickel Phosphorus layer with significant advantages over traditional electrolytic nickel coatings. The absence of coating thickness complications that are created by current density provides a nickel deposit that is extremely uniform in coverage and thickness. This unique characteristic makes the Electroless Nickel (EN) process ideal for plating engineered components that are complex in shape and require tight “after plating” tolerances.

There are many different types of Electroless Nickel coatings and processes available to meet different applications, conditions and requirements. Physical and mechanical properties of the coating such as hardness, corrosion resistance, magnetism and solderability vary from one EN process to another depending on deposit Phosphorus content, bath formulation and post plate treatments.
