Prepackaged Magnesium Buried Anodes ( Cotton Bag) High Grade Magnesium Alloy M1C According To ASTM International

Cast sacrificial magnesium anode

High grade magnesium alloy M1C according to ASTM International (ASTM) B843.

Magnesium alloyed anodes designed for buried applications. The high driving voltage makes the anodes well suited for structures buried in soil with resistivities exceeding 2 000 ohm-cm. The efficiency of the anodes is further enhanced as the anodes are pre-packaged in a specially designed backfill, which lowers the anode-to-soil resistance, and hence make the current flow to the targeted structure easier.

Chemical Composition

Environment-friendly Backfill

The added backfill helps to decrease the electrical resistance of the anode to the ground as well as retain moisture which allows for better efficiency and homogeneous consumption of the anode, thus creating an efficient anode bed. Our backfill is prepared with naturally degradable and recyclable materials in the following weight ratio*:

• Hydrated Gypsum: 75%
• Bentonite: 20%
• Sodium Sulphate: 5%

The content of harmful elements in the backfill is below the industrial safety standards, meaning it will not introduce any pollution to the surrounding environment.

• Cadmium ≤ 1 ppm
• Arsenicum ≤ 1 ppm
• Mercury ≤ 1 ppm
• Phosphorus ≤ 10 ppm

* Other specialized mixture compositions are available upon request.
