Magnesium Anodes

High-quality magnesium anodes with the highest driving voltage among all sacrificial anode materials. Ideal for soil with medium to high resistivity.

PRODUCT OVERVIEW

Superior Electrochemical Performance

Magnesium anodes provide the highest driving voltage among all materials used for sacrificial anodes, making them ideal for challenging environments.

🔋 Standard Potential (H-1)

Manufactured in accordance with ASTM B843-AZ63B standard, containing 90% magnesium, 6% aluminum and 3% zinc. Ideal for soil conditions where resistivity is under 3,000 Ω·cm with driving potential of -1.55 volts.

⚡ High Potential (HP)

Manufactured from 99% pure magnesium according to ASTM B843-M1C standard. Open circuit potential as high as -1.7 volts, providing 20-30% greater protection than standard potential anodes. Perfect for high-resistivity environments exceeding 2,000 Ω·cm.

APPLICATIONS

Versatile Solutions

Typical Applications of Magnesium Sacrificial Anodes across multiple industries and environments.

🏗️ Underground Pipeline Protection

For protecting underground pipelines in soils with medium to high resistivity. Standard potential anodes work best in low resistivity soils (≤3000 Ω·cm), while high potential anodes are ideal for high resistivity environments (>3000 Ω·cm).

🛢️ Storage Tank Bottom Protection

Installed beneath above-ground storage tank bottoms to prevent corrosion, suitable for both new construction and retrofit projects. High potential anodes provide enhanced protection in challenging soil conditions.

🚿 Water Heater & Tank Protection

Internal protection for water heaters, boilers, and water tanks. Magnesium anodes provide effective galvanic protection in freshwater applications.

🔌 Buried Cable Protection

Corrosion prevention of metallic sheaths for buried cables in various soil conditions. The high driving voltage of magnesium makes it effective even in challenging environments.

⛰️ High-Resistivity Soil Applications

Particularly effective in sandy, rocky, or mountainous areas where soil resistivity exceeds 2,000 Ω·cm. High potential magnesium anodes deliver superior performance in these challenging conditions.

⚡ Grounding System Protection

Protection of grounding rods, anchor bolts, and valve boxes. Magnesium anodes provide reliable long-term protection for critical infrastructure components.

🌊 Specialized Marine Applications

While primarily designed for soil applications, certain magnesium formulations can be used in specific marine environments where galvanic protection is required.
