Q. When we we choose to use Zinc anodes ?
Exterior of underground or underwater pipe
Interior of pipe handling corrosive waters and effluents
Lead sheathed electric cable in ducts
Other metal-sheathed electric cable in underwater or underground locations
Copper concentric neutrals of URD cable
Corrosion control and/or grounding of induced AC on underground pipe
Annulus space between outer steel casing and inner pipe of deep wells
Interior bottoms of oil storage tanks
Foamed annulus space of insulated steel pipe underground or underwater
Double bottom areas of ship ballast tanks
Bottom areas of cargo/ballast tanks of petroleum carriers


AZ31 Extruded Magnesium Anode rod and AZ63 Cast Magnesium Anode for water heater
1. Magnesium anode rods is one of the most essential parts of a standard hot water heater .
It helps to prevent tank corrosion and rusting.
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. KIG can offer all kinds of extruded magnesium anode rods
and we can produce according to customers' requirements.
2. Advantages:
2.1.Magnesium anode rods create the higher voltage they create during the sacrificial process.
It can protect the water heater with low cost.
2.2 Extruded Magnesium anodes have high surface and length ratios in relation to cross sectional size.
This allows these anodes to deliver a greater amount of current per weight than cast anodes.
3. Application:
Magnesium anode rod can be used in water boiler, heat exchanger, water container, house heaters, RV heaters,
water dispenser, heat plumbing, oil, natural gas, coal gas, et.It releases electrons into the water heater tank, which
helps slow or prevent corrosion in the tank.
