Zinc-Nickel plating : providing corrosion resistance and protection from galvanic corrosion
In the past 20 years many studies on different plating methods have been carried out by both the automotive and aerospace industries. Zinc-Nickel plating is now seen as the preferred alternative to the toxic cadmium plating and an improvement over traditional zinc plating. Zinc-Nickel plating, free of both cadmium and hexavalent chrome VI, has been selected as the environmental friendly finish for the BlueFast® range of hexagonal k-nuts and floating anchor nuts.
Zinc-Nickel plating has been widely used in the automotive industry for over 20 years and offers the following advantages:
- Zinc-Nickel plating provides greater resistance to corrosion when compared to zinc plating, salt spray test results have shown up to 4 times greater.
- Zinc-Nickel plating reduces the risk of galvanic corrosion when using dissimilar materials.
BlueFast® k-nuts and anchor nuts are used in high performance applications and not only meet the ELV Directive but also provide designers with an environment friendly value added fastener solution.
