Mg anodes with diameters ranging from 0.500" to 2.562" with
stainless steel caps
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.

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.
