What Metals Are Used in Sacrificial Anode Rods?

Sacrificial anodes are usually made from relatively pure active metals, such as magnesium, aluminum, or zinc. These more active metals (anodes) oxidize and corrode much faster than the less active metals (cathodes).

• Magnesium generates around -1.6 volts

• Aluminum generates around -1.1 volts

• Zinc generates around -1.05 volts

As a result, magnesium anode rods tend to work better (succumbs to corrosion faster), but don’t last as long as other metals.

The anode rod is “self-sacrificing” and will continue to corrode until eventually it must be replaced. When there’s no sacrificial metal left on the anode, the tank can rust out, eventually causing it to burst.
