Description: Engine heat exchangers have a common problem of corrosion due to the difference in metal between casing and tube stack. Employing zinc pencil anodes reduces the corrosion on the casing prolonging the life of both casing and tube stack whilst in seawater. Zinc is the only material that has an official specification, the American MIL-A-18001 K spec. Zinc is a well-proven anode material and its capacity is virtually unaffected by the operating current density, although the driving voltage diminishes with increasing temperature, therefore, it has limited application. If zinc is not to this specification i.e. high purity zinc 99.99%, it will have a limited use as an anode material because of an iron present as an impurity.
