Product Description
The HB-MGS25-1200 Magnesium Alloy AZ63 segmented anode rod is engineered for superior cathodic protection in underground storage tank applications. This anode rod provides long-lasting corrosion prevention by sacrificially protecting the tank interior, heating elements, and internal components from galvanic corrosion, extending equipment service life significantly.
- High-purity magnesium alloy AZ63 for standard water heating applications
- Continuous cast steel core for uniform current distribution
- Low electrical resistivity below 0.3Ω·m for efficient protection
- Corrosion rate controlled below 0.5mm/year in typical water conditions
- Open circuit potential -1.55V provides robust driving voltage
