we attach a copper lead wire (size, length and insulation type as
specified) to the H-1 anode and seal the connection interface. If
required, the H-1 anode will be packaged in a cloth bag with
prepared backfill mixture of 75% gypsum, 20% bentonite and 5%
sodium sulfate. The backfill mixture works to maintain moisture
around the anode and lowers the anode to earth resistance. The
packaged anodes are shipped on pallets in plastic bags that must be
removed prior to installation.

Electrochemical Properties of cast magnesium anodes |
Item | Open-circuit Voltage | Close-circuit Voltage | Actual capacitance | Current efficiency |
| (-V) | (-V) | (A.h/g) | (%) |
High Potential | 1.70-1.75 | 1.57-1.62 | ≥ 1.100 | ≥ 50 |
Low Potential (AZ63) | 1.50-1.55 | 1.45-1.50 | ≥ 1.105 | ≥ 50 |
Note: Open and Close-circuit voltage is relative to Saturated
Calomel Electrode (SCE) |
Application:
In cathodic protection, the most widely used sacrificial anodes are magnesium anodes. When
high potential magnesium anodes are required for high current
application
Mg anode is manufactured from high purity primary magnesium under
strict, state of the art production techniques, anode chemistry,
testing and certification
