Specifications

Cast Magnesium Anodes are widely used in the Cathodic Protection(CP) industry.

Cast Magnesium Anodes are widely used in the Cathodic Protection(CP) industry. Cathodic Protection is one of the most common methods of corrosion mitigation in the pipeline, storage tank and underground metallic structures.

 

We supply various shapes and sizes of cast magnesium anodes. The most commonly used sizes are 9 lb, 17 lb and 32 lb.  We also take orders per customers drawings.
