Is Zinc Nickel Plating Right For Your Project?

Manufacturers use zinc-nickel plating to finish a wide range of components and products. You might now be sure if zinc-nickel finishing is the right solution for your work. Here are a few problems that are ideal for this process.


One of the biggest arguments for using a zinc-nickel finish is to prevent corrosion. If you are going to use a product in a setting where rust or discoloration are major issues, zinc-nickel finishing may be a great solution.

Notably, it's a sacrificial layer. In other words, this finish is there to take the hit. It isn't 100% corrosion-resistant, but the out layer will corrode before the substrate does. With regular monitoring, you should be able to send parts back to a zinc-nickel plating services provider once they show signs of corrosion. They can then strip the parts and apply a new layer.


Not all finishes are ideal for applications involving odd shapes, nooks, and crannies. If you have a component that is far from uniform in shape, there's a good chance that coating it in zick-nickel will do the job because the material is ductile. That means it can be reshaped with ease and without losing strength. Consequently, a zinc-nickel plating services company can apply it to a metal substrate of almost any shape without expecting weakness.

Thermal Stress

Some components have to hold up against heat and friction. Once more, the zinc-nickel coating can serve as a sacrificial layer. It won't last forever, but you should be able to spot when a component needs a fresh finish before it causes trouble. In the meantime, it will absorb a lot of the beating that the substrate metal would otherwise suffer.

Electrical Conductivity

Zinc-nickel is an extremely conductive material. Never consider it for an application where it will come into contact with electricity unless you want a good flow. Otherwise, you'll have to find a high-quality insulator to prevent the transmission of electricity across the material.


The most common competing application is cadmium plating. Unfortunately, that process generally is much less environmentally friendly than working with zinc-nickel plating.

Different Metals

Some metals don't play nicely with each other. If you have to use them, one way to allow them to the interface is to use zinc-nickel finishing as a buffer. You will have to strictly monitor wear and tear, though, to prevent the metals from coming into contact.
