An introduction to zinc nickel plating

Zinc nickel plating is widely used across engineering sectors to improve the durability and lifespan of metal components. It offers a balanced combination of corrosion protection and wear resistance, making it suitable for demanding environments in which standard zinc coatings may fall short. Let’s take a look at it in more detail.

How the process works

Zinc nickel plating involves applying an alloy coating containing around 10-15% nickel to a metal substrate using an electrolytic process. The addition of nickel strengthens the coating structure and enhances performance. The process can be tailored to specific requirements by adjusting bath chemistry, deposition thickness, and post-treatment steps.

Key benefits and performance

The main advantage of zinc nickel plating is its high level of corrosion resistance, particularly in harsh or salt-rich conditions. It also provides solid wear protection, helps prevent hydrogen embrittlement when correctly processed, and offers a stable base for paint or other secondary finishes.

Uses across industries

Zinc nickel plating is commonly applied in the automotive sector for fasteners, brake components, and structural brackets. Aerospace manufacturers use it for hardware that must withstand fluctuating temperatures and exposure to corrosive agents. It is also used in industrial machinery, electrical connectors, and energy sector equipment due to its combination of strength and protective qualities.

Zinc nickel plating delivers a reliable and versatile protective finish suitable for many engineering applications. Its corrosion resistance, durability, and compatibility with secondary coatings make it a strong choice for industries in which component integrity is essential.
