Magnesium anodes are used for cathodic protection of ships and boats, particularly in freshwater and other environments with low electrical conductivity. Due to their high electrochemical potential, magnesium anodes can provide effective protection where other sacrificial anode materials may deliver insufficient protective current.

They are commonly used to protect hulls and other submerged metal components against corrosion. Selecting the correct anode type, size and placement is important to achieve effective protection while avoiding unnecessary anode consumption.

At Corrosion Group, we offer magnesium anodes in a range of sizes and designs for different marine applications. We can also assist with anode selection and system design based on the vessel, operating environment and required service life.

With more than 35 years of experience in anode manufacturing, we produce custom-made anodes for a wide range of cathodic protection applications. Anodes can be manufactured in aluminium, zinc and magnesium, with weights ranging from 0.05 kg to 90 kg. Design, material and dimensions can be adapted to the requirements of each application.

Magnesium anode rods are ideal for protecting water heaters and other tank-based systems from internal corrosion, extending their lifespan effectively. Their high potential ensures optimal performance in a variety of water conditions.

Magnesium wire anodes provide flexible and efficient corrosion protection for pipelines and other underground structures. They are easy to install and adapt to complex layouts.

Magnesium shaft or collar anodes are specifically designed to protect rotating equipment, such as ship propellers and shafts, from corrosion in freshwater environments.

Magnesium hull anodes offer superior protection for boats and marine structures in freshwater, effectively shielding the hull from corrosion caused by electrochemical reactions.

Backfill magnesium anodes are used in buried or submerged applications, paired with a special backfill mix to ensure consistent current distribution and maximum protection for pipelines and storage tanks.

Custom magnesium anodes are tailored to meet specific dimensions and performance requirements, offering corrosion protection solutions for unique structures and specialized applications.

We are one of Scandinavia's leading suppliers of cathodic protection since 1989. Our headquarters are located in Ramlösa, Helsingborg, in southern Sweden.
