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. This anode is typically made of high-grade zinc and has a cylindrical shape, resembling a pencil, hence the name. The purpose of the pencil zinc anode is to attract and corrode instead of the metal it is protecting, thereby extending the lifespan of the metal structure. It works through a process called 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 necessary to ensure effective protection against corrosion in marine environments.
