HITEC EN 6786 A/B/C High PhosphorusElectroless Nickel

▪ HITEC EN 6786 High Phosphorus Electroless Nickel Plating is an advanced electroless nickel-phosphorus (Ni-P) alloy plating process designed to deliver superior performance in demanding applications. This innovative process is characterized by its exceptional bath stability, high phosphorus content ranging from 10-14% by weight, and an impressive deposition rate of 10-18 µm/hour, making it one of the fastest and most efficient high-phosphorus electroless nickel plating solutions available.

▪ The high phosphorus content in HITEC EN 6786 results in a coating with a unique amorphous microstructure, which significantly enhances its corrosion resistance. This makes the process particularly suitable for applications in highly corrosive environments, such as those encountered in the marine, chemical processing, and oil and gas industries. The coating's ability to withstand prolonged exposure to aggressive media, including acids, alkalis, and salt sprays, ensures long-term protection for critical components.

▪ HITEC EN 6786 produces a semi-bright to bright coating with excellent surface finish, which not only meets but often exceeds the stringent requirements of industry standards such as MIL-SPEC 26074D and AMS 2404B. These standards are widely recognized in the aerospace and defense sectors, where reliability and performance are paramount. The coating's uniformity and consistency make it ideal for complex geometries, including parts with deep recesses, blind holes, and intricate designs, ensuring complete coverage and protection.

▪ In addition to its outstanding corrosion resistance, the high phosphorus content also provides excellent non-magnetic properties, making HITEC EN 6786 suitable for applications in the electronics and telecommunications industries, where magnetic interference must be minimized. The coating also exhibits superior barrier properties, preventing substrate oxidation and improving solderability and weldability, which are critical for electronic and electrical components.

▪ The process operates at moderate temperatures, typically between 85-90°C, and offers excellent bath life and operating window, reducing the need for frequent maintenance and chemical replenishment. This results in lower operational costs and improved production efficiency. Furthermore, HITEC EN 6786 is compatible with post-plating treatments such as heat treatment, which can further enhance the coating's hardness and wear resistance. Heat treatment transforms the amorphous Ni-P structure into a crystalline Ni3P phase, increasing the hardness to over 1000 HV, making it suitable for high-stress applications.

▪ HITEC EN 6786 is also highly versatile, capable of plating on a wide range of substrates, including aluminum alloys, stainless steel, carbon steels, alloy steels, and copper alloys, among others. This versatility makes it an ideal solution for multi-material assemblies and hybrid components, ensuring consistent performance across diverse applications.

▪ In summary, HITEC EN 6786 High Phosphorus Electroless Nickel Plating is a cutting-edge plating solution that combines exceptional corrosion resistance, high deposition rates, and superior surface finish. Its ability to meet and exceed industry standards, coupled with its operational efficiency and compatibility with post-plating treatments, makes it an indispensable technology for modern manufacturing and engineering applications. Whether used for functional performance or decorative finishes, this process delivers consistent, high-quality results that meet the stringent demands of today's industries.
