Product Description

A Magnesium Anode measuring 21mm x 1185mm is typically used in cathodic protection systems to prevent corrosion, particularly in applications involving metals exposed to water or soil, such as pipelines, boats, water heaters, or underground tanks. Magnesium anodes are often chosen for their high electrochemical potential, which makes them effective in protecting metals from corrosion.

Here’s a breakdown of the specifications:

Magnesium Anode:
- Magnesium is a commonly used material for sacrificial anodes because of its ability to corrode (sacrifice itself) in place of the metal it is protecting.
- When connected to the metal object you want to protect, it corrodes instead of the object, thereby prolonging the life of that metal.
Dimensions:
- 21mm Diameter: This refers to the thickness or diameter of the magnesium rod. In this case, it’s a relatively small diameter, which is typical for applications where the anode needs to fit into confined spaces or where a lower current output is needed.
- 1185mm Length: The length of the magnesium anode indicates the surface area of the material, which directly affects its efficiency in protecting a given surface area from corrosion. A longer anode typically provides more protection and lasts longer.
Applications:
- Water Heaters: Protects the metal tank from corrosion due to water exposure.
- Boats and Marine Equipment: Used to protect metal parts from saltwater corrosion.
- Pipelines: Installed along pipelines to prevent corrosion from water or soil exposure.
- Underground Tanks: Helps in protecting buried tanks, preventing corrosion over time.
Function:
- When installed, the magnesium anode undergoes a process called galvanic corrosion, where magnesium (being more reactive) sacrifices itself to protect the steel or other metals it is connected to.
