Zinc-nickel plating

Why zinc-nickel coatings?

In areas subject to maximum corrosion – such as engine or brake components – where standard electro-plating reaches its limits as regards extensive heat and the influence of de-icing salt in winter, alloy coatings comprising 85-90% zinc and 10-15% nickel have proved to be excellent alternatives.

Minimum layers for maximum protection

The positive features of electro-plated zinc-nickel coatings:

Maximum cathodic corrosion protection – even at layer thicknesses of 5 µm (important for fitting)
No voluminous corrosion products
Up to 1000h protection against backing material corrosion (red rust) in salt spray test as per DIN 50021 SS
High thermal capacity to 180°C
No contact corrosion when combined with aluminium
Chromated (CrVI)
With passivation (CrVI-free)
With sealing option
Lubricant coating for defined coefficients of friction

What secondary treatment?

The right secondary treatment is decisive for the appearance and white rust resistance of your zinc-nickel-coated workpieces. Combined with the suitable layer thickness of the zinc-nickel coating, it provides maximum protection against red rust. The appropriate secondary treatment allows both decorative and silver-coloured (transparent) or black layers to be produced as well as functional layers such as those with defined coefficients of friction, for example.
