Meeting OEM Specifications with Zinc-Nickel Plating Services
Precision Matters in Automotive Plating
When it comes to automotive parts plating, there’s no room for compromise. Every component must meet rigorous OEM specifications — from corrosion resistance and coating thickness to adhesion, torque-tension behavior, and surface appearance.
As a proven zinc-nickel plating company, DeKalb Metal Finishing partners with OEMs and Tier 1 suppliers to deliver highly engineered zinc-nickel plating services that meet or exceed global specification standards across multiple industries.
The Complexity Behind OEM Compliance
OEM plating specifications are not one-size-fits-all. They often include detailed parameters such as:
- Specific alloy compositions (e.g., 12–16% nickel in zinc-nickel)
- Required hours of neutral salt spray resistance
- Trivalent passivates and/or topcoats for additional protection
- Functional properties like conductivity, ductility, and wear resistance
- Surface finish standards (e.g., color, gloss, texture)
At DeKalb, we don’t just “hit the spec” — we engineer the finish to integrate seamlessly with your part’s design, application, and performance goals.
Zinc-Nickel Plating Services Built for Spec Performance
We specialize in three core plating systems to meet a wide range of OEM specifications:
- Zinc-Nickel Alloy (ZnNi): Ideal for high-performance corrosion resistance and heat exposure applications.
- Zinc-Iron Alloy (ZnFe): Excellent for high-volume fasteners requiring enhanced ductility.
- Pure Zinc: A cost-effective, RoHS-compliant solution for general corrosion protection.
Available finishes vary by plating system and can include a full range of trivalent passivates — such as clear, black, or yellow for applicable zinc and zinc-alloy deposits — along with optional sealers. This gives OEMs complete flexibility to meet diverse global specifications.
The DeKalb Advantage: Process Control + Technical Expertise
