Black Zinc Nickel Plating

The zinc plating process can be considered an excellent primer for paint surfaces with the paint protecting the zinc giving a lasting protection.

Black zinc nickel plating.

Black zinc nickel plating is now available on a wide variety of connectors and accessories including mil dtl 38999 and proprietary mil c 26482 ranges of connectors. Zinc nickel has received increasing commercial acceptance over the past 20 years. Zinc nickel plating deposits are made of zinc with a few percent of nickel in it maybe about 6. The fully qualified z class is an aluminium shell with rohs compliant black zinc nickel plating.

The plated coating generally consists of 11 to 16 nickel and the remainder as zinc many specifications allow a larger range but best performance is usually found in this. Black zinc nickel plating. Zinc nickel exceeds the following performance requirements. It provides long lasting corrosion resistance to exposed connector surfaces used on commercial aircraft and military planes transportation vehicles and marine transports.

Black nickel plating kit 1 5 gallon. Astm b841 ams 2417 bac. This conductive and nonreflective black finish is approved for 500hrs salt spray endurance and is fast becoming the new defence industry standard. This plating is free of cadmium hexavalent chromium lead and any other substances identified as hazardous by the eu and it has now been adopted as a standard across the globe.

Zinc plating with black chromate offers better corrosion resistance and anti galling characteristics than black oxide. It offers the same level of electrical performance harsh environment protection and temperature ranges as cadmium fininshes. Zinc plating involves an electrolytic application of zinc to metal by immersing clean steel parts into a zinc plating bath and applying electric current to it. The idea is that this plating still offers sacrificial protection to steel like zinc plating does but due perhaps to incapsulating itself in more stable corrosion products it does not corrode as quickly as zinc and thereby provides substantially more corrosion resistance.

Black nickel plating kit this kit gives a beautiful translucent black nickel coating over most metals including nickel copper brass tin steel stainless steel and zinc. Mix up the chemicals with distilled water clean your parts with the included. Zinc nickel plating can be passivated to further improve its corrosion resistance. And black chromates are available.

Innovative black zinc nickel finish is a rohs compliant cost effective and sustainable plating alternative to cadmium. Black zinc coating acts as a barrier to protect the steel from many damages such as corrosion and improves the appearance.
