Anodes protect the various metal components on a yacht (propellor shaft, keel, rudder, engine) from the deterioration caused by galvanic corrosion.
Galvanic corrosion (also called electrolyte) is the deterioration of metal which occurs when dissimlar metals are joined together by a conductor in an electrically conductive fluid. The least noble metal (the anode) dissolves while the most noble metal (the cathode) remains protected.
Select the anode metaal composition according to the nature of the water: Salt water = zinc anode; see product range below
Fresh water = magnesium anode
Brackish (mixture of salt and fresh) water: aluminium anode
