ASTM B841 Zinc Nickel Plating
High-Performance Corrosion Protection for Severe-Duty Components
Fukar provides zinc nickel electroplating services for components that operate in aggressive environments and require longer corrosion life than conventional zinc plating. The process is widely used for automotive, transportation, and industrial fasteners under demanding service conditions.
Our zinc nickel process is controlled under ISO 9001:2015 quality management and aligned with ASTM B841 requirements. We manage alloy composition, coating thickness, and post-treatment to meet customer corrosion performance targets.
Where required, we also support process comparison against standard zinc and electroless nickel so your engineering team can select the best-fit corrosion system.
Performance Highlights
Why Engineers Specify Zinc Nickel
500+ Hour Corrosion Resistance
Designed for demanding corrosion targets where standard zinc performance is not sufficient.
12–15% Nickel Alloy Content
Controlled alloy composition supports stable, repeatable electrochemical performance.
Improved Heat Tolerance
Suitable for components exposed to elevated temperatures in automotive and industrial systems.
Technical Reference
Zinc Nickel Specification Snapshot
Zinc nickel selection depends on alloy content control, coating thickness, post-treatment system, and operating temperature profile. Requirements are confirmed during technical review before production.
Our team can align process output to your drawing notes and quality documentation requirements.

How It Works
Zinc Nickel Plating Process Flow
1. Pre-cleaning
Degreasing and cleaning remove oils and contaminants before plating.
2. Activation
Surface activation helps ensure stable and uniform zinc nickel deposition.
3. Zinc Deposition
Controlled electroplating to target alloy composition and thickness based on specification.
4. Passivation
Passivation and optional topcoat applied to meet corrosion requirements.
5. Drying
Parts are dried and handled using controlled finishing procedures.
6. Final QA
Final checks for thickness, appearance, and process compliance records.
Common Questions
Zinc Nickel Plating FAQ
Answers to common technical questions from purchasing, QA, and engineering teams.
Ask a Technical QuestionWhat is zinc nickel plating used for?
Zinc nickel plating is used for components that need stronger corrosion protection than standard zinc, especially for automotive brake, fuel, and underbody systems.
What nickel content is typical in zinc nickel plating?
Zinc nickel systems are typically controlled around 12–15% nickel content, depending on the customer specification and performance target.
Which standard is commonly used for zinc nickel plating?
Zinc nickel plating is commonly specified to ASTM B841, with additional OEM or customer standards supported where required.
What salt spray performance can zinc nickel plating achieve?
Many zinc nickel systems can achieve 500+ hours neutral salt spray resistance under ASTM B117 reference conditions, depending on coating system design.
When should zinc nickel be selected over standard zinc?
Zinc nickel is selected when standard zinc is not enough for corrosion life or heat exposure, especially in severe-duty automotive and industrial applications.
