Zinc Nickel Plating Services

Zinc nickel plating services continues to be the favoured finish for the automotive industry. It is also being specified by all European manufacturers for under bonnet and under car.

This is because it achieves very high levels of corrosion resistance. It also produces only small amounts of corrosion product. This enables sub assembles to be dismantled easily so reducing warranty repair costs.

Here at EC Williams, we have been investing since the 1990s in this plating finish. This means we can ensure that we have the most up to date, and advanced barrel lines available.

After 15 years of leading the way in the barrel plating of this process, we have now upgraded to the latest high efficiency chemistry system.

This has improved our throughput and, as a result, increased our capacity. Naturally, it meets all automotive OEM specifications, as well as offering a range of top coats, lubricants and sealants. These enable corrosion resistance in excess of 1000 hours salt spray performance.

Zinc Nickel Plating Services as Chosen by the Aerospace Industry

We are now also seeing the Aerospace industry move to zinc nickel, as a replacement for Cadmium. The reason for this is that like Cadmium, Zinc Nickel coated components can be fixed to aluminium, without causing a galvanic cell, which would accelerate corrosion.

We Have a Wide Range of Clients

Zinc nickel plating services are also used widely in other industries. At EC Williams, we appreciate our wide ranging clients from the rail and power generation industries through to the spring and fastener manufacturers.

All of our zinc nickel coating clients benefit from our extensive range of post plating treatments, including chromate passivates. These passivates are available in both trivalent clear and trivalent black.

If required, top coats such as torque control lubricants and silicate sealants are readily available. For our clients in the high tensile fasteners and springs market, we have excellent de-embrittlement facilities on our state of the art site.

Highest of Standards

You can rest assured when you choose EC Williams for your zinc nickel plating services, that we rigorously test all our plating to the highest of standards.

At the beginning of the plating process we start with the careful analysing of the plating solution by our highly trained technicians. At the end of the process, with the finished product, we conclude with the certification of the coating thickness and alloy content. This is performed by our X-Ray Fluorescence test equipment.

All of this impeccable attention to detail is combined with a flexible and competitive pricing structure. This allows for varying batch sizes and understands the needs for rapid turnaround.
