What is the efficiency percentage of a magnesium anode?

The efficiency percentage of a magnesium anode is typically around 50%. This figure represents how much of the total energy that the anode produces effectively contributes to the cathodic protection process. Magnesium anodes are commonly used in cathodic protection systems due to their relatively high driving potential and effectiveness in protecting structures from corrosion in various environments, especially in fresh water and soil applications.

Understanding the efficiency of magnesium anodes is essential for proper system design and implementation, as it affects the overall performance and the longevity of the cathodic protection system. The choice of anode material and its efficiency must be matched to the specific requirements of the application to ensure optimal protection against corrosion.
