Sacrificial Anodes of Zinc and Aluminum, Galvanic Protection

MtoNauticastore.it offers anodes and zincs for pleasure boating and fishing. Essential to prevent galvanic corrosion of the engine and hull when the boat is in the water, anodes and zincs are available in a wide range of types, dedicated to the main brands of engines and accessory parts. The sacrificial anode is essential to protect the hull and the engine and all those metal parts from corrosion and galvanic currents. It is called a sacrificial anode as it is "sacrificed" by corroding itself to protect the boat and parts of it. The sacrificial anodes also called zincs must be replaced every year or whenever they have corroded.
There are different types of sacrificial anodes based on its use and there are zincs for marine engines that have cathodic protection for the parts of the outboard and / or inboard motor and the zincs for propellers that protect them from galvanic corrosion caused by galvanic currents.
These zinc or sacrificial anodes must not be covered or painted and must have good contact with the hull or engine.
To protect the boats from galvanic currents, metal blocks are installed which can be zinc, aluminum or magnesium. Galvanic currents attack and corrode metals, but since these anodes are made of a less resistant material than the hull or the engines, they are consumed first, preserving the materials that make up the engine, transmission, keel, propeller on which they are applied. The sacrificial anodes do not have to be made of zinc but can be made of aluminum or magnesium depending on the areas of mate in which the boat is located. It is preferable to use zinc or aluminum anodes in salt water, while magnesium anodes are used in hot water
