Alkaline Zinc-Nickel (Zn-Ni) plating is a highly advanced electroplating process that builds upon the benefits of traditional alkaline zinc plating by co-depositing a small percentage of nickel (typically 12-16%) with the zinc. This alloy coating provides significantly enhanced corrosion protection and other desirable properties, making it a preferred choice for demanding applications, especially in the automotive industry as a replacement for cadmium plating.
Alkaline Zinc Nickel Alloy ( 85-15 ), barrel & rack, plating on Steels, with Tri-Chrome Passivation and Lacquer Top Coat, as per international standards, capable of withstanding up to 720 hours Salt Spray and beyond testing for corrosion resistance until red rust. Equipped with state of the art Fischer XRF inspection
Provides exceptional protection against corrosion, often 5 to 10 times better than standard zinc plating, especially against red rust. This makes it a high-performance alternative to cadmium.
Offers excellent "throwing power," which ensures a consistent and uniform coating thickness even on parts with intricate shapes, deep recesses, or blind holes.
The alkaline process is less prone to causing hydrogen embrittlement, making it a preferred choice for high-strength steels and critical components where part integrity is essential.
Due to its high corrosion resistance and lower environmental impact, it serves as an effective and widely accepted substitute for toxic cadmium plating in the automotive, aerospace, and defense industries.
The process allows for better control of the nickel content (typically 12-15%) in the deposited alloy, which is crucial for achieving optimal corrosion performance.
