What is cathodic protection?
Cathodic protection is an electrochemical process which halts the natural reaction (corrosion) of metals in a particular environment by superimposing an electrochemical cell more powerful than the corrosion cell. Sacrificial Anodes are fitted or bonded to the metal to be protected which in turn as it has a greater electrical potential than the anode material becomes cathodic and causes the anode to waste instead of itself.

WHY USE MARTYR™ ANODES?
Anodes are inexpensive which means it is important to protect your boat with a quality product. Martyr anodes are pressure diecast and manufactured to strict quality standards through an ISO 9001 Quality Management System. In addition, each alloy is guaranteed to be manufactured to the latest US Military Alloy Specification and is chemically tested regularly at their in-house labs to ensure consistency. Poorly manufactured anodes may contain high levels of impurities such as iron, which will leave your investment unprotected.

Fit the correct anode material for the waters your vessel is operating in.
As a general rule owners should fit the anodes suitable for the environment they most regularly berth in and the following table provides a useful guide :
