Electroless Nickel Plating per MIL-C-26074, ASTM B733 and AMS 2404

Electroless nickel plating is an process that codeposits a nickel-phosphorous alloy without need for an externally applied electrical current.  The electroless nickel plating process occurs from a chemical reduction of the nickel ions within the electroless nickel solution onto a metallic substrate rather than deposition of the ions from an applied current.  As a result, the electroless nickel deposit is free of many of the problems associated with traditional electrolytic nickel including edge buildup and non-uniform coating.  Electroless nickel deposits are extremely uniform, corrosion and erosion resistant and provide excellent lubricity.

The nickel plating process produces a silver-white deposit that is used for both engineering and decorative applications. It can be applied with a matte, sulfur-free appearance, semi-bright, or mirror bright finish by controlling the composition and operating parameters of the plating solution. The hardness of the nickel plate can also be varied from 150 to 500 Vickers, it has a low coefficient of thermal expansion and nickel is magnetic. For all these reasons, nickel is used in a wide variety of industries including automotive, appliances, hardware, plumbing, jewelry, aerospace, defense, and circuit boards. In decorative applications, nickel has an ability to cover imperfections in the base metal; this is referred to as leveling. As an undercoat for silver or chrome plating, the nickel will maintain its luster even under the severest conditions and it also works as a barrier against corrosion of the base metal.

We had experience to molded PEI, PEEK, PPS or any kind Ultra Polymer material based parts, then apply for Nickel Plating process.
