Zinc Nickel Plating is widely used in industrial and commercial industries to offer the best protection against corrosion, extending the life of the carbon steel products without compromising the surface it is being plated on. Zinc Nickel plating provides great protection against corrosion than zinc plating process as adding nickel slows the zinc corrosion process and is highly resistant to thermal loads (up to 120 °C). In Zinc nickel alloy plating, the combination consists of 6-20% nickel and 80-94% zinc. This type of metal finishing is usually used on steel, ferrous cast components, and powdered metals.

In this blog post, we are going to share everything you need to know about zinc nickel plating including its advantages, and uses. But before moving to its uses and advantages, you should know what zinc nickel plating is?

What is Zinc Nickel plating?

Zinc Nickel is an acid or anodic coating that is used for providing corrosion protection to steel, iron, copper, and brass. Zinc Nickel is identified as an environmentally and safe alternative option to cadmium plating that means this surface finish process is a replacement of cadmium plating.

In galvanic interaction applications, where the coating is meant to reduce the corrosion caused by the reaction of dissimilar metals, Zinc Nickel can replace cadmium for enhanced corrosion protection, specific torque-tension requirements, or color identification. In the last decade, the use of zinc nickel plating is gaining popularity in the automotive and industrial sectors to provide corrosion protection to components and various metal parts.

Benefits of Zn Ni Plating

Zinc nickel plating is a highly effective and inexpensive coating process with minimum environmental harm that offers superior corrosion resistance, with providing a coating that can go for 250+ hours to first white corrosion and 1,000+ hours to first red corrosion and provide rust prevention as well.

It provides uniformity of metal plate distribution and outstanding covering power. As stated, even after being exposed to high temperatures and shock, it remains anti-corrosive, bright and burn-free.

With this plating process, you can get a smooth, uniform, and durable coating with tight dimensional tolerance.
It has excellent adhesive characteristics after post-plate bending or forming, making it a perfect fit for bondable rubber to metal applications.

The good alloy distribution, and excellent deposit distribution makes it an ideal coating, especially for automotive parts. This plating process is compatible with passivation that further enhances the corrosion resistance of the deposit.

Applications of Zinc Nickel Plating

Mostly used in the automotive industry to provide greater corrosion protection for various automotive parts.

Zinc nickel plating is used in the electrical transmission industry for the manufacturing of anchors, coaxial cables, and cleat bolts.

Aerospace and Defense industries use zinc nickel plating because zinc nickel is compatible with the lighter metals such as magnesium and aluminum that are widely used in manufacturing aircraft parts and components.

Other uses of zinc-nickel plating are in the manufacturing of firefighting and railway equipment, as well as commercial transportation vehicles such as cars, buses, trucks, tractors, etc.
