Feature: The basic role of magnesium rod: anti-corrosion and anti-scaling, protect the inner tank. 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. 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. Great replacement of the old one 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 Specification: Material: Magnesium Alloy (AZ31B) Standards: EU Environmental Standards Package list: 2 * Magnesium Anode Rod, 1 * Adhesive tape(roll) Note: The actual product color may deviate from the photo due to light.
