Malleable Magnesium Water Heater Anode Rod

Flexible Magnesium Water Heater Anode Rod: A versatile solution designed to combat interior corrosion in water heaters. Provides efficient protection by diverting corrosive action away from tank walls, extending the system’s lifespan. Ideal for narrow spaces and limited access areas, offering a healthier and eco-friendly alternative.



Water heaters commonly suffer from internal corrosion due to minerals in water, exacerbated by high temperatures. Anode rods are crucial in preventing this corrosion and extending tank life by diverting corrosive action away. Our flexible magnesium anode rod, with carbon steel or stainless steel wire, suits tight spaces where rigid rods can’t fit. It’s ideal for areas like low ceilings, closets, or basements, providing eco-friendly protection as magnesium dissolves naturally over time, leaving sediment.

Quality Substrate Material
We manufacture our high-quality flexible magnesium anode rod according to the American standard ASTM B843-AZ31B. This ensures top-grade performance and reliability in water heater applications.

Element ASTM B843 – AZ31B
Aluminum (Al) 2.5 ~ 3.5%
Zinc (Zn) 0.6 ~ 1.4%
Manganese (Mn) 0.2 ~ 1.0%
Silicon (Si) 0.1% Max
Iron (Fe) 0.005% Max
Copper (Cu) 0.01% Max
Cadmium (Cd) 0.04% Max
Nickel (Ni) 0.001% Max
Total Impurities 0.3% Max
Magnesium (Mg) Remainder


Segmented Design
Compared with a cast magnesium rod, this extruded magnesium rod has better machining accuracy. The 45 inch long rod is hinged into four sections, allowing for easier installation in cases with limited access. The product can be safely cut to fit the water heater as required.

Uniform Current Distribution
The magnesium anode rod is designed with a steel core that extends along its entire length, ensuring even and efficient distribution of current for consistent and reliable performance.

Easy Replacement
The anode rod is readily replaceable and should be inspected during every water heater tank drainage. Typically, anode rods need replacement when roughly 75% of their mass has corroded. Our anode rod is anticipated to offer approximately two years of safeguard against corrosion.

Strict Quality Control
Our flexible magnesium anode rods are crafted in adherence to ISO 9001:2015 standards, ensuring rigorous manufacturing, inspection, and testing processes for optimal performance.

Customized Configurations
This flexible magnesium anode rod fits Rheem, BWC, AO, STATE, and other solar or electric water heaters equipped with a standard ¾” NPT thread. Tailored segments, lengths, and threads can be provided upon request.
