Quick thruster BTQ250 anode - packed

Anodes play an essential role, sacrificing their own material to protect metals from corrosion.

Regular maintenance is crucial, as once they are over 60% worn, they lose their effectiveness.

For seawater, zinc or aluminum alloy anodes are recommended.

For the same current, an aluminum anode weighs three times less than a zinc anode, has a higher electronegative potential and pollutes less.

They are particularly suitable for protecting aluminum hulls.

For use in freshwater, magnesium anodes are preferable.
