Low-Phosphorus Electroless Nickel Plating

Low-phosphorus electroless nickel plating is a surface coating technology preferred especially in applications requiring high wear resistance and good electrical conductivity, with a phosphorus content of 1.5% – 3%. Also known as electroless nickel plating, this method occurs through a chemical reaction without the need for electric current and provides uniform coating thickness on different materials.

As Erkap Industrial Coating Solutions, we offer high-performance and long-lasting coating solutions for stainless steel, alloy steels, castings, aluminum, copper, and their alloys with our low-phosphorus electroless nickel process.
