Feature:_x000D_ _x000D_ The basic role of magnesium rod: anti-corrosion and anti-scaling, protect the inner tank. _x000D_ Magnesium rods, also known as anode rods, are mainly composed of magnesium. Inside the water heater liner, it and the inner liner (mainly iron) are in contact with water at the same time, forming a primary battery due to chemical principles. _x000D_ Since the water in the inner tank is not pure water, it always contains various impurities and has certain corrosiveness. When the water temperature exceeds 40 C, scale will be generated. If there is no magnesium rod, the inner tank will be corroded. _x000D_ Great replacement of the old one _x000D_ Mainly used in water boiler, heat exchanger, evaporimeter, and boiler and so on. It has properties of softing water, de-dirt residual ,en-longing the working life of containe _x000D_ _x000D_ Specification:_x000D_ Material: Magnesium Alloy (AZ31B)_x000D_ Standards: EU Environmental Standards_x000D_ _x000D_ Package list:_x000D_ 2 * Magnesium Anode Rod,_x000D_ 1 * Adhesive tape(roll)_x000D_ _x000D_ Note:_x000D_ The actual product color may deviate from the photo due to light._x000D_ There may be a slight deviation in the measurement of product.
