A range of industries rely on Zinc Nickel Plating for their corrosion resistant and durable parts, which don’t necessarily require a decorative finish.
Automotive Underbody Parts
Components such as brake brackets, brake calipers and suspension mounts are subject to corrosion from salt water, moisture and temperature. In corrosion testing such components achieve in excess of 1,000 hours in salt spray testing. This makes Zinc Nickel alloy plating the ideal corrosion protective coating for such components.
Aerospace Fasteners and Brackets
Aerospace Engineering: Zinc Nickel Plating Specifications. Aerospace specifications for thin, uniform coatings for components of complex geometry for engineering to procurement specifications (eppss) for corrosion protection.
Hydraulic Fittings
Hydraulic fittings and valves need a coating to protect them from the fluid they are carrying and from being subjected to high pressures. A good alloy for this application has strong adhesion to protect against flaking off, and good ductility to resist cracking.
Military and Defence Hardware
There is more on Zinc Nickel Plating at swmf.co.uk/surface-coatings/zinc-nickel-alloy-plating. Zinc nickel plating is often required by military procurement to be a RoHS compliant coating which does not contain hexavalent chromium. Zinc nickel plating offers excellent corrosion protection.
Brake System Components
Most coatings will crack and peel when subjected to repeated thermal cycling. The zinc nickel alloy plating, however, is able to withstand the heat of a brake system.
If your part is going to be exposed to harsh environments, or you have specific corrosion protection specifications that need to be met, then early consideration of Zinc Nickel Alloy Plating should be given.
