Electroless Nickel Plating

The electroless nickel plating services we provide at Alexandria Metal Finishers are used to provide a corrosion and wear resistant surface on a variety of metal substrates. Electroless nickel continues to gain favor in a variety of industries due its combination of desirable material properties and ability to provide complex parts with a very uniform plating thickness. We offer medium and high phosphorous nickel plating to defense, aerospace, and commercial manufacturing standards using manually controlled processes. Electroless nickel offers corrosion and wear resistance as well as a low coefficient of friction, making it ideal for a number of machinery components and other harsh applications. We can carefully control the plating thickness, depending on the grade of material used, resulting in a uniform part that rarely requires additional processing.

Although it has been used extensively for a number of years, electroless nickel is still considered a relatively new plating process, and is misunderstood by many in the industry. This is partially due to the inability of many finishing providers to properly apply the plating. Since electroless nickel plating relies on a chemical reduction reaction, control of the process is critical in obtaining optimum results. A typical EN bath is more sensitive to operating conditions than an electroplating bath, and care must be taken to control the process within relatively tight parameters to achieve the best performance.
