Zinc Nickel Plating

Zinc Nickel Plating

Zinc nickel plating (Zn-Ni) has replaced cadmium as the plating standard in the auto industry for preventing corrosion in the harshest environments. Besides meeting various corrosion-resistance specifications for automotive applications, manufacturers can formulate zinc nickel to meet industry standards in electronics, aerospace, and defense.

Allied Industries Plating Company offers superior-quality with its zinc nickel plating process which combines industry-best chemical processes with high-performance plating equipment. We produce exceptional results regardless of the size or complexity of the job.

A VERSATILE, PROVEN, ANTI-CORROSION SOLUTION.

Zinc Nickel plating serves many applications across several industries, including:

Automotive: Fluid transfer tubes that form into specific shapes rely on zinc-nickel plating for fabrication. Zn-Ni can also plate fasteners for components used in high-corrosion areas, like chassis joints and parts under the hood.

Electronics: Zn-Ni delivers high electrical conductivity and corrosion resistance for many electrical applications, including plating for connectors as a direct replacement for cadmium.

Defense and Aerospace : Applications in defense and aerospace include joining materials with aluminum and plating engine components on military vehicles.

Zn-Ni plating is a solution for protecting automotive components against severe conditions in some areas of Europe and North America with harsh winter environments. When crews spread salt, sand and calcium chloride on roadways for safety, these particles breach exposed surfaces, causing harmful cavities and erosion. The zinc-nickel plating acts as an effective barrier against that penetration.

Zinc-nickel plating has received increasing commercial acceptance over the past 20 years, as many industries have pushed for a high-performance solution against corrosion. Engineers sought plating processes that would go beyond zinc and even replace cadmium. The automotive industry was a critical driving force in the acceptance because Zn-Ni allowed automakers to extend their warranties and reduce claims, a positive outcome for both manufacturers and consumers.

In addition, zinc-nickel plating has replaced cadmium to become the standard in the aerospace industry


A HIGH-PERFORMING ANTICORROSION SOLUTION FOR SEVERAL INDUSTRIES

There are a wide array of zinc nickel plating applications for the automotive, electronic, aerospace, and defense industries. Automotive applications include fluid transfer tubes, which can be formed into their required shape after plating. Zinc nickel is used to plate fasteners for use in high corrosion areas (under the hood and chassis joints). In electronics, zinc nickel is used to plate connectors, where it has been used as a direct cadmium replacement. Zinc nickel delivers corrosion resistance and high electrical conductivity. Its aerospace and defense industry applications include joining components to aluminum.

Zinc nickel plating has received increasing commercial acceptance over the past 20 years. Various industries pushed concertedly for higher corrosion performance. They sought solutions that would go beyond the capabilities of zinc, and/or even replace cadmium. The automotive industry was a key driving force because car manufacturers have sought to extend their warranties and reduce warranty claims for some time.


ZINC NICKEL PLATING SPECIFICATIONS & BENEFITS

Some of the specific benefits our zinc-nickel plating process offers include the following: Increased corrosion protection, often 5-6x greater corrosion protection vs. standard zinc plating. Highest performance and tolerance to elevated temperatures, excellent for components exposed to high heat such as in the engine compartment.

ACID AND ALKALINE ZINC-NICKEL ALLOY PLATING SERVICES

Allied Industries provides zinc-nickel plating services using acid, alkaline and trivalent passivation options.


Alkaline Zinc Nickel Plating

Several primary features of the alkaline zinc-nickel plating process are:

Superior ductility that’s critical to the successful plating of fluid lines, fittings, tubular items and components. The ability to maintain corrosion performance while enduring extreme pressures and secondary processing. The highest corrosion resistance. The highest hardness properties compared to all zinc and zinc alloys. Superior anti-scratch performance.

Acid Zinc Nickel Plating

Features of the acid zinc-nickel plating process include:

  • Used primarily on cast iron components, high carbon steel, and carbo-nitrided steels
  • Most notably used on brake calipers
  • Provides high deposit brightness, brake fluid compatibility, chip resistance, hot dust resistance, and paint adhesion
  • Trivalent Passivation Options for Zinc-Nickel Plating

    Trivalent Zn-Ni offers superior corrosion resistance and other properties without the presence of restricted substances contained in hexavalent alternatives. Many of these plating solutions feature distinct colors like:

  • Clear blue, transparent
  • Yellow, iridescent
  • Black
