Product Description
25mm Magnesium Alloy Hex Head Anode Rod 1 NPT 1000mm Heavy-Duty Replacement for Commercial Water Heater
Product Overview
The HB-MGH25-1000 Magnesium Alloy AZ63 hex head solid anode rod is engineered for superior cathodic protection in commercial water heater 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.
Key Features
- 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
