Zinc anodes are mainly used in seawater and brackish water. Zinc anodes can be used in brackish water if the resistivity is not too high (approx. 1.5 Ωm). Zinc is more chemically stable than Aluminum and is therefore preferred by many in weakly brackish water environments.

The term «zinc» has become synonymous with sacrificial anodes, as zinc was the original material used for this purpose. But other metals, such as aluminum and magnesium, also act as sacrificial anodes.

With over 30 years of experience, you as a customer can always feel safe with our products. We manufacture everything according to international standards and industry guidelines. Each batch of anodes undergoes careful testing and quality assurance, as it has been for over 30 years …
