Hull anodes for ships and boats - Zinc, Aluminum and Magnesium
Hull anodes
Why use hull anodes for cathodic protection?
Sacrificial anodes
Which metal in which type of water?
Salt water
For optimal protection on your hull that is in salt water, Aluminium anodes is the right choice for you.
Freshwater
In fresh water however, we recommend Magnesium anodes for the best possible protection of your hull.
Brackish water
For brackish water which is a mixture between fresh and salt water, we recommend the use of our Aluminium anodes or Zinc anodes. This is because it is difficult to determine how salty or fresh the brackish water is without any water samples. Fell free to contact us if you have any doubts.
There are several important factors that must be considered before choosing the type of sacrificial anodes. For example, the size of what you want to protect, other parameters such as painting/coating is also important. Should you need help calculating the number of anodes to protect your hull from corrosion, you are always welcome to contact us with your question. Remember that an anode that has been consumed about 50% from its original appearance and weight should be replaced.
What should I do if my hull is made of a material other than steel?
