Magnesium Anodes for Cathodic Protection Applications
Magnesium Anodes are sacrificial anodes used in cathodic protection systems where a high driving voltage is required for suitable applications. RELI SLEEVE Magnesium Anodes can be manufactured in application-specific configurations according to approved engineering requirements, applicable standards and customer specifications.
MAGNESIUM SACRIFICIAL ANODES
Magnesium Anodes Product Introduction
Magnesium anodes are sacrificial anodes used as part of galvanic cathodic protection systems. Magnesium has a relatively high electrochemical driving voltage and can therefore be considered for applications where this characteristic is required by the cathodic protection design.
Magnesium sacrificial anodes are commonly considered for selected applications involving soil, freshwater and other environments where their electrochemical characteristics are appropriate.
The selection of magnesium, aluminium or zinc anodes should always be based on the protected structure, electrolyte, required current output, design life, installation conditions and approved cathodic protection calculations.
RELI SLEEVE can support project-specific magnesium anode requirements with application-specific dimensions, configurations and manufacturing based on approved drawings and specifications.
