Zinc alloy sacrificial anodes exist on the basis of electrochemical principles, which use the more active electrochemical properties of zinc to prevent the corrosion of other metals.

When the zinc alloy sacrificial anode comes into contact with the metal it needs to protect, it will voluntarily oxidize and transfer the corrosion reaction of the metal to itself.

This reaction can effectively slow down or prevent the corrosion of metal structures and extend their service life.
