For many applications zinc-nickel alloy plating is superior to standard zinc plating. Due to the complexity of zinc-nickel plating, it has only become cost effective in recent years as technology has improved. Zinc-nickel is now seen by many as an improvement on zinc plating and as an alternative to toxic cadmium plating. TECHNO SHINE offer zinc-nickel plating at a variety of thicknesses. Unpassivated, clear passivated or black passivated finishes are available. Topcoats are also available.
Zinc nickel bridges the galvanic gap between steel and aluminium, reducing the risk and rate of galvanic corrosion. In this way, it works similarly to cadmium. Zinc-nickel is still sacrificial and so provides some protection to the steel even in the event of small scratches, cracks etc.
