Magnesium anodes are used in such systems, most commonly to protect
underground gas, oil and water pipelines.
Magnesium anodes come in two alloys. H-1 or AZ-63 is 90% magnesium,
6% aluminum and 3% zinc. The zinc and aluminum lowers the cost of
the anode but it also lowers the driving potential to about -1.55
volts referenced to a copper sulfate electrode. It will perform
well in corrosive soil if the tank is well coated and will last
longer than the high potential alloy. The other alloy is 99% pure
magnesium. It is called a "high potential" anode as its open
circuit potential is as high as -1.80 volts. It works better than
the H-1 alloy anode in dry or resistant earth or where more current
is needed because of a poorly coated tank. The higher potential
forces more current to flow than would from an H-1 alloy anode. It
costs more per pound but in many cases it is worth the extra cost.
High Potential (HP) Cast Magnesium anode is the best choice for CP
systems in high resistivity soil since it is made from the high
purity magnesium which provides higher electrochemical and
efficiency.
