Magnesium Sacrificial Anode

Commonly used in cathodic protection systems because Mg metal has a more negative potential than other galvanic materials. Our production plant uses high quality magnesium metal which exceeds normal standards used to manufacture anodes.

R, D and S Type anodes are available as stock items in the specifications which follow.

Any item required that is not a stock item can be manufactured according to the customer specification. This would include Hull, Tank and Rectangular anodes.

All can be supplied in packaged forms.

High Potential Mg Anode

Made from high purity Mg metal these anodes are manufactured using advanced casting technology and have superior electrochemical properties.

Tested to ASTM97-89.

In service the anode is consumed uniformly thereby extending its useful life.

Usually used in soils with a resistance higher than 2000 ohm/cm.
