Features Magnesium Material: Magnesium rod, also known as anode rod, is mainly composed of magnesium. Professional Made: In the water heater liner, it and the inner liner (mainly iron) are in contact with water at the same time. Due to the chemical principle, the primary battery is formed, which can prevent corrosion and scale. Fine Workmanship: When the water temperature exceeds 40℃, scale will be generated in the water heater. The combination of magnesium rod and iron can protect the inner container from corrosion. Premium Material: The powered anode rod is made of environmentally friendly magnesium alloy for durability Scope of Application: The anode rod is suitable for large hot water tanks such as motorhomes Specification: Product Material: AZ31B Environmental Magnesium Alloy Product Standard: EU Environmental Standards   Package List: 1 * Water Heater Anode Rod Package List
