MG Duff Zinc Weld On Anodes



Saltwater oxidation wears out metal parts frequently. This causes them to fail faster if they are not protected by a sacrificial anode.

A sacrificial anode consists of a metal alloy, such as Zinc, that has a more active voltage when it is introduced into the electrolyte current. The Zinc has a greater negative electrochemical potential than other metals when it is placed into salt water.

The purpose of the Zinc is to have it “sacrifice” its electrons faster than the metal it is mounted to.

As the Zinc anode is pulled apart during the electrolyte process, the other metal is protected as the electrolytes are more attracted to the active voltage that the Zinc anode possesses.
