They are manufactured from magnesium, aluminum, or zinc-aluminum alloy. Protect against galvanic corrosion with anodes for every software. Applications embrace engine anodes, hull anodes, shaft anodes, rudder anodes and prop anodes.
The more reactive metal will corrode fully before the second metal begins to rust. Since aluminum and magnesium are way more reactive in comparison with the steel used to make the tank, it stands to purpose that the rod will corrode and depart the tank protected.
The way we counteract galvanic corrosion is to add a 3rd metallic into the circuit, one that is quicker than the opposite two to give up its electrons. This piece of metallic known as a sacrificial anode, and most often it is zinc.
West Marine also stocks pencil anodes to protect water heaters. Choose zinc anodes for saltwater, aluminum anodes for brackish water or magnesium anodes for freshwater. Protect your inboard/outboard engine with … Read MoreRead More »
