Mid-Phosphorus Electroless Nickel Plating

Mid-phosphorus electroless nickel plating is an advanced surface coating technology that provides a balanced combination of corrosion resistance and wear resistance with a phosphorus alloy content of 7% – 9%. Also known as electroless nickel plating, this method occurs through a chemical reaction without the need for electric current and ensures uniform coating thickness even on parts with complex geometries.

As Erkap Industrial Coating Solutions, we offer high-performance and environmentally friendly solutions for automotive and industrial applications with our next-generation mid-phosphorus electroless nickel process that eliminates the use of lead and cadmium.
