Magnesium Anodes
Magnesium anodes are used for fresh water applications; for salt or brackish water use our zinc anodes or rods. All magnesium pencil anodes and rods contain a steel core. If you don't see the size of anode or rod that you need, please email, fax, or call us and we will work with you to get you what you need.
Unless otherwise noted, all rods are made to a standard anode grade of the following:
3% Aluminum, 0.2% Manganese, 1% Zinc, 95.8% Magnesium
None of the Magnesium Products can be used for fire starting, they must be 99.9% pure.
NOTE- The Length of the Pencil anodes with the plugs, is the OVERALL length with the plug - They can easily be cut shorter if needed
