Zinc Nickel Plating

Zinc nickel plating is an electroplated alloy coating process that can significantly improve a base material’s corrosion resistance. At Saporito Finishing Co., we offer zinc nickel plating services in addition to zinc plating and a range of other plating and coating solutions.

What Is Zinc Nickel Plating?

Zinc nickel plating uses a blend of zinc and nickel content for enhanced resistance to corrosion in harsh environments. In many cases, applications can use zinc nickel plating as a reliable alternative to cadmium plating. The resulting finish enhances overall durability while preparing surfaces for the application of additional coatings for further finishing.

Benefits of Our Zinc Nickel Plating Services for Corrosion Resistance

Zinc nickel plating is a sacrificial coating for steel, suitable for a range of industries, including marine, automotive, electronics, hydraulics, and agriculture. The main advantage of zinc nickel coating is increased corrosion resistance, as the nickel alloy maximizes the zinc’s ability to withstand harsh environmental conditions. Other benefits of zinc nickel plating include:

Three times the hardness value of conventional zinc plating
Greater resistance to corrosion, with the ability to apply chromate coatings for added durability and sealants for a lower friction coefficient
Increased throwing power and superior coverage in low current density areas
Uniform coatings on simple to intricate designs

Zinc Nickel Metal Finishes We Offer

Using electroplating, we offer several types of zinc nickel plating solutions to meet your coating requirements.

Trivalent Zinc Nickel Plating

This zinc nickel alloy consists of around 85% zinc and 15% nickel, with unique coloration ranging from silver to blue to iridescent purple that sets it apart from other finishes. It offers as much as 10 times the level of protection seen with traditional zinc plating. Zinc nickel is a functional coating and is normally done for aesthetic purposes.

Black Zinc Nickel Plating

Another option is black zinc nickel plating, which uses black trivalent chromate for sealing and offers five times the durability of traditional zinc. This finish is ideal for parts benefiting from minimal visibility, such as components under a vehicle hood.

Our Processes and Capabilities for Zinc Nickel Plating Services

We combine many years of experience in plating and finishing with top-tier customer service, which we use to provide products and services for applications in the telecommunications, hydraulics, automotive, die casting, aerospace, and defense sectors, among others.

Our team utilizes advanced, automatic lines with features like ultrasonic carrier detection to safeguard customer parts during processing. Our patented floating rack system is designed to enhance this process, especially for parts with blind holes such as tubes, cups, or cans.

Following plating, we can apply a post plate seal to further enhance the finish’s corrosion resistance and coefficient of friction for torque tension modification.
