How to choose this product
ship-sacrificial-anode

A ships sacrificial anode protects the hull from corrosion. NauticExpo offers aluminum, zinc, magnesium and other types of anodes.

Applications

Such anodes fight ballast tank and hull corrosion. They are usually mounted on areas prone to corrosion, for example, between the propeller and the rudder.

Technologies

When two metals are in contact under water, the less noble has a lower electrical potential than the more noble. This creates an electrical current from the more to the less noble metal, driving the latter's ions into the water, causing it to corrode. Since the sacrificial anode is less noble than the metal parts of the ship, it protects them by corroding in their place.

How to choose

Choice will depend on the anode's weight, size, shape and constituent material.

Advantages

- Inexpensive
- No maintenance necessary

Disadvantages

- Must be replaced every one to five years
