Cadmium plating was used on many components for corrosion protection. It was effective. However, it was also highly toxic to people and the environment. As stricter regulations have been introduced and awareness of toxic substances has grown, over recent years worldwide across industries, manufacturers have looked for alternative coatings that are safe and equally effective. Zinc nickel has become one of the most popular alternatives to cadmium.
The Risks Associated with Cadmium
Cadmium is a highly toxic heavy metal that can cause harm to human health and the environment. Inhaling cadmium particles over a long period of time can cause lung disease, including cancer. Heavy metals, such as cadmium, that are present in wastewater and solid waste can cause environmental harm through contamination of water and land resources.
Why Zinc Nickel Is Considered Safer
Zinc nickel coating typically combines high zinc content with a smaller amount of nickel, creating a finish that is far less hazardous than cadmium. Both metals are easier to manage safely during processing and disposal. This makes working environments safer and reduces environmental impact, while still delivering excellent corrosion resistance comparable to cadmium.

Performance Without Compromise
Zinc nickel is a highly versatile coating with a wide range of properties that can be used in a variety of applications beyond just electrical safety. The coating can be used in extremely harsh environments and is often used where the part requires a certain level of corrosion resistance, wear resistance, or chemical resistance.
