Alkaline Zinc Electroplating
Alkaline zinc plating is the most advanced zinc plating technology, providing superior corrosion protection and a bright, uniform finish. Using an alkaline (non-cyanide) bath chemistry, this process offers exceptional throwing power — the ability to coat deep recesses, holes, and complex geometries uniformly.
Ideal for automotive components, structural hardware, and industrial fasteners, our alkaline zinc line delivers consistently high-quality results at production scale.
- Coating thickness: 5–25 microns
- Salt spray resistance: 72–240 hrs
- Bath type: Alkaline non-cyanide
- Process temp: 20–35°C
- Plating efficiency: 95%+
- RoHS compliant available
Iron Zinc Electroplating
Iron Zinc (Zinc-Iron alloy) electroplating is an advanced alloy plating process that combines the corrosion resistance of zinc with the enhanced hardness and wear resistance of iron alloys. The result is a coating that outperforms pure zinc in demanding environments.
With iron content typically between 0.4–0.8%, the Zn-Fe alloy provides significantly improved salt spray test performance and is widely specified by OEMs in the automotive, heavy equipment, and infrastructure sectors.
- Alloy composition: Zn + 0.4–0.8% Fe
- Salt spray resistance: 200–500 hrs
- Coating thickness: 8–25 microns
- Enhanced wear resistance
- Superior hydrogen embrittlement relief
- Suitable for high-strength steels
Passivation (chromate conversion coating) is applied after zinc plating to significantly enhance corrosion resistance and provide a distinctive appearance. We offer four passivation types to meet all OEM and industry specifications.
Blue Passivation
Clear/blue chromate conversion coating. Provides a bright, clean appearance with good corrosion resistance. Most commonly used for general hardware and fasteners.
Trivalent Yellow Passivation
RoHS-compliant trivalent chromium (Cr³⁺) yellow passivation. Environmentally safe alternative to hexavalent with excellent corrosion protection for automotive and export parts.
Hexavalent Yellow Passivation
Traditional hexavalent chromium (Cr⁶⁺) yellow passivation. Provides maximum corrosion resistance for non-export, heavy-duty industrial applications.
Black Passivation
Premium black chromate conversion coating for aesthetic and functional requirements. Widely used in automotive trim, electrical components, and precision instruments.
Our Plating Process
Every component undergoes a stringent multi-step process to ensure flawless coating quality from raw part to finished product.
