Description
The Hull Anode ZD72B is a 12kg zinc anode with 200 to 225 bolt centres. have been at the forefront of marine cathodic protection since the 1950's. These hull anodes provide excellent cathodic protection in salt water environments. A zinc alloy made with a much wider efficient mild steel core, this anode is one of the popular bolt on types used on the majority of boats.
Anodes are installed on boats for the purpose of sacrificial protection, also known as cathodic protection. Boats are made of various metals, such as steel, aluminum, and bronze, which can undergo galvanic corrosion when immersed in an electrolyte like seawater. Galvanic corrosion occurs when two dissimilar metals are in electrical contact in the presence of an electrolyte, causing one metal (the less noble or more reactive metal) to corrode rapidly while the other metal (the more noble or less reactive metal) remains protected. Anodes, typically made of metals like zinc or aluminum, are deliberately installed on the boat's hull and underwater fittings. So the anode "sacrifices" itself rather than let the sittings corrode.
