The advantages of Aluminum Anode
?
1. High current capacity gives most suitable for large-sized long life anode.
2. Small anodic polarization tendency gives stable protective current throughout anode life.
3. Optimum diving voltage without over-protection.
4. Uniform anode consumption.
5. No hydrogen hazard due to its very low rate of generation.
