Anodes

To prevent electrochemical corrosion, hull anodes, collar anodes and rudder anodes should be attached to the underwater ship hull of metal ships, and metal ship propellers, shaft devices, rudder shafts, bow thrusters or keels. An anode consists of a less noble metal than the ship hull, so it oxidizes, i.e. it releases electrons into the water. The ship hull absorbs electrons and does not oxidize. Due to oxidation, galvanic anodes are consumed or sacrificed over time and must be replaced after a while. For this reason, they are frequently named … Read more

… sacrificial anodes. Sacrificial anodes are available in different shapes, e.g. bread-shaped, as block anodes or as rod anodes. The anodes can either be welded onto the ship hull or screwed onto stud bolts or base plates. In saltwater, which has the highest electrochemical conductivity, zinc anodes should be used. If the ship operates alternately in saltwater, brackish water and fresh water, aluminium anodes are recommended. Magnesium anodes are particularly suitable in fresh water and when sailing alternately in brackish and fresh water. For professional vessels and yachts made of aluminium, there are special zinc anodes with aluminium arms. In addition to the anodes listed here, we also supply other sizes and anode types on request.
