Product Description

Pencil Zinc Anode

A pencil zinc anode is a type of sacrificial anode commonly used in marine applications to protect metal structures such as boat hulls, propellers, and other submerged parts from corrosion. Made of high-quality zinc and shaped like a cylindrical pencil, it attracts and corrodes instead of the metal it is protecting, thereby prolonging the life of the metal structure. This is achieved through galvanic corrosion, where the electrical potential difference between the anode and the protected metal causes the anode to corrode instead. Regular inspection and replacement of pencil zinc anodes are essential for maintaining effective corrosion protection in marine environments.
