Alkaline Zinc Nickel Plating

Alkaline zinc-nickel plating is an advanced electrolytic coating process that provides significantly higher corrosion resistance than conventional zinc plating. Containing approximately 12–15% nickel, the coating substantially enhances surface performance and provides long-lasting protection, particularly under demanding service conditions.

Recognized as one of the most preferred surface coating technologies by today's automotive manufacturers, zinc-nickel plating is widely used for critical safety components thanks to its excellent high-temperature resistance, chemical durability, and extended service life.

• Provides significantly higher corrosion resistance than standard zinc plating, offering outstanding protection against red rust.
• Delivers superior wear resistance compared to other zinc alloy coatings.
• Maintains its protective properties at elevated temperatures.
• Suitable for hardened steel components and critical applications such as braking systems and engine compartments.
• Ensures uniform coating thickness across all surfaces.
• Cyanide-free process with an environmentally responsible formulation.
• Performance can be further enhanced with passivation and topcoat applications.
• Offers extended maintenance intervals and lower life cycle costs.

• Automotive fasteners
• Brake systems
• Fuel systems
• Hydraulic equipment
• Defense industry
• Agricultural machinery
• Heavy-duty machinery
