| 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:
anodes are recommended for use in low-resistivity soils typically below 2,000 ohm-cm. Because the anodes have a lower driving voltage than high-potential anodes, they are ideally suited for structures where over protection is of concern. Their lower-current output also allows these anodes to operate longer than their high potential counterparts in more conductive environments.
