MG Duff Bolt On Zinc Anodes



Zinc anodes are the preferred choice in metal alloys for saltwater applications that need a sacrificial anode. This is because the alloy is less resistant to the saltwater’s electrolytes.

The Zinc, in essence, stops the oxidation happening to the other metal part as the Zinc dissolves away.

The amount of Zinc anodes that are needed to protect the other metal surface will be based on several factors, such as how much of the other metal part will be in constant contact with the saltwater, what type of metal is the part made out of, and what type of shape must the Zinc anode be made into.
