17Ibs Bare Magnesium Anode

Description

Product description:

The magnesium anode Howah supply is used as a sacrificial anode in cathodic protection. Magnesium has the highest driving voltage of all the materials used for sacrificial anodes.

Magnesium is low on the noble scale, and therefore corrodes easily. Therefore, if it is placed within a system that uses large amounts water, it attracts the corrosion away from other components.

Application of 17Ibs/7.7kg 17D3 Bare Magnesium Anode

 

Magnesium anodes fight corrosion effectively and economically, and are commonly used in marine environments. They protect a variety of steel structures in salt, brackish and fresh water, including:

1.Boats

2.Ballast tanks

3.Bulkheads

4.Water storage tanks

5.Pilings

6.Pipelines

7.Heat exchangers
