Selection guide
How the anode materials compare.
A quick reference to typical properties. Your CP design determines the final choice.
| Property | Aluminium (Al-Zn-In) | Zinc | Magnesium |
|---|---|---|---|
| Main service environment | Seawater and marine | Seawater, marine and saline mud | Soil and fresh water |
| Closed-circuit potential | More negative than −1.05 V (Ag/AgCl) | Approx. −1.03 V (Ag/AgCl) | Approx. −1.5 to −1.7 V (Cu/CuSO₄) |
| Electrochemical capacity | 2,550 – 2,750 Ah/kg | Approx. 780 Ah/kg | Approx. 1,100 – 1,230 Ah/kg |
| Density | Approx. 2.7 g/cm³ | Approx. 7.1 g/cm³ | Approx. 1.8 g/cm³ |
| Key strength | Highest capacity per kilogram — fewer, lighter anodes | Proven, self-regulating and compact | Highest driving voltage for high-resistivity electrolytes |
| Points to check | Chemistry must be tightly controlled to stay active | Heavier; not recommended above approx. 50 °C | Consumed quickly; generally not used in seawater |
Typical reference values for comparison only. The correct material is always confirmed by the approved CP design for the structure and its environment.
