20X300 Mm M6 Magnesium Anode Rod Fit Solar Water Heater Systems With Copper Nut
Magnesium anode for water heater
Water heater anode rod or sacrificial anode is the important component part with only one purpose to protect metal tank from corrosion.Extruded Alumnium anodes and Magnesium anodes have high current to weight ratio,are suitable to be used in where a small diameter anode is required to give enough cathodic current.
Advantages:
(1)Corrosion protection,
(2)protect water heater, water containers of steel structure,
(3)protect the gas pipeline in-home service polarization high resistance electrolytes (soil and water in the steel structure)
