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.
