Zinc Nickel Electroplating 

WHY ?

Produces a clean finish with no imperfections

High corrosion resistance

Low temperature Plating

Max Temp is 65 deg. Celsius

No Twisting or Warping

Thickness ranges from 5 to 15 microns

Perfect for outdoor use under powder coating 

This new technology incorporates an alloyed matrix system that is deposit thickness controllable to between 6 to 18 microns. In controlled NATA Neutral Salt Spray testing to ASTM B117 guidelines; comparative HDG and Zinc Nickel coated parts were accelerated corrosion tested with the Zinc Nickel articles out performing the HDG articles to a red rust failure mode.The unique galvanic corrosion cell character created by the inclusion of nickel in the zinc layer allows for excellent longevity of components in all corrosion environments including coastal applications.

The coating system is not only compliant to the nominated corosivity categories detailed in AS/NZS 2312.2 and ISO9223 but as an alloyed zinc electro-galvanized coating exceeds the listed “Life to first Maintenance years and severity classifications” as listed. The new zinc alloy coating system finds applicable reference with the Australian Standard AS4100-1998 which qualifies coating selection as per the requirements of AS/NZS2312. and additionally as per AS3556.2-2002 cites- (non alloy) electroplated zinc passing class 3 environments i.e. 1000hours, whilst the new alloy coating exceeds class 3 environmental performance and offers excellent coastal conditions application.

In summary the new Zinc Nickel Alloy is set to provide a new level of high corrosion resistant zinc alloy protection on selected steel component applications and can be chosen as an alternative to Hot Dipped Galvanizing or Powder Coated finishing as required.
