Zinc anodes can be used in brackish water if the resistivity is not too high (approx. 1. 5 m). 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.
