ASTM water heater anode used in solar water heater parts
Extruded Magnesium Anode Rod Water Heater in solar water heater parts
Magnesium rods are excellent sacrificial rods, used to protect the inside metal surface of your water heater tank. The magnesium corrodes instead of your tank. Magnesium anode rods tend to be consumed quicker than Aluminum or Aluminum/Zinc/Tin anode rods due to the higher voltage they create during the sacrificial process.

Office, Workshop, Inspection Lab:
Water Heater Anodes are available in several configurations, with welded or unwelded Hex-Head and Anode Outlet Devices (AODs). These anodes are typically used for the Cathodic Protection of Water Heaters, Tanks and Boilers. The linked-style water heater anodes are typically for replacement applications.
