The Use Of Zinc Nickel Plating
When it comes to the choice of metal finishing options, including electroplating, there are several different options that OEMs can consider. Working closely with a metal finishing company offering different forms of electroplating provides the OEM with the information and professional recommendations to ensure the correct process is used based on the requirements and environmental working conditions for the part or component.
In applications where a long life cycle in highly corrosive or damaging environments is important, one of the most suitable types of electroplating options is zinc nickel plating. This type of plating option can be used on a variety of metals and alloys, including cast iron, copper, malleable iron, brass, and steel parts and components. For this reason, as well as the effectiveness of the process in protecting the part, it is often used in the automotive industry.
Superior Corrosion Resistance
Today, the use of zinc nickel plating largely replaces the use of cadmium electroplating. It is safer for the environment and reduces the toxicity of the old style of cadmium electroplating processes. IT is RoHS compliant, which also adds to the ability of OEMs to distribute parts or components and stay within all international compliance responsibilities.
In addition to this, zinc nickel plating provides a very high level of corrosion resistance. This includes resistance to salt spray as well as the contact or interaction of the plated part with other metal components in the system or equipment.
As a sacrificial coating, the use of zinc nickel electroplating allows for longer protection of the base metal. This is provided through the zinc nickel actually corroding before the base metal, adding to the durability of the part.
