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.

Standard : ASTM G-97

The anode rod is the most important factor in determining the life of your water heater. An anode rod is a steel core wire surrounded with one of three different metals. These metals include aluminum, magnesium, and zinc. The rod is screwed into the top of your water heater and protects your water heater from rusting. When the tank is filled with water the anode rod sacrifices itself to protect the exposed steel of the water heater, through a method called electrolysis. Electrolysis happens when there are two pieces of metal connected inside of water, the process makes the anode rod corrode in place of the exposed steel in your water heater. During this process the more noble (less reactive) metal will corrode over the less (more reactive) noble metal. Aluminum, magnesium, and zinc are all much less noble than steel, meaning they will corrode before the steel, which is why they are used for anode rods.
Our anodes are shipped worldwide especial main to North America, Asia etc., around 5000mt per year. Our goods are regularly tested by independent third party lab in USA to keep anode continuous high quality. Our plant owns raw material resources ore, so we can supply very good price with service for you.
We can also accept customized anodes with your logo according to your drawing !
