Overview
CerAnode™ Magnesium Galvanic Anodes provide dependable, self-powered cathodic protection for buried steel structures and assets operating in high-resistivity soils and freshwater environments. As one of the most active sacrificial anode materials available, magnesium delivers a high driving voltage that provides effective corrosion protection without the need for rectifiers or external power.
Designed for underground and inland applications, CerAnode™ magnesium galvanic anodes are available in a variety of sizes, alloy compositions, and pre-packaged configurations to simplify installation and deliver reliable, long-term corrosion protection for pipelines, storage tanks, water systems, and other buried infrastructure.
Key Features & Benefits
High Driving Voltage
Magnesium provides one of the highest driving potentials among galvanic anode materials, making it ideal for high-resistivity soils and low-conductivity environments.
Self-Powered Corrosion Protection
Generates protective current without rectifiers, external power supplies, or complex electrical infrastructure, providing immediate galvanic protection after installation.
Optimized for Buried Applications
Engineered for reliable performance in soil and freshwater environments where magnesium offers superior current output compared to other galvanic anode materials.
Available Pre-Packaged or Bare
Offered in multiple alloy compositions with optional pre-packaged backfill to improve current distribution and simplify field installation.
Proven, Low-Maintenance Performance
Passive operation and predictable consumption provide dependable long-term corrosion protection with minimal maintenance requirements.
Typical Applications
- Buried transmission and distribution pipelines
- Aboveground and underground storage tanks
- Water heaters and freshwater storage systems
- Well casings and underground vessels
- Valve stations, utility infrastructure, and buried metallic equipment
- Temporary cathodic protection during construction or system commissioning
