Product Description
GB 4948 Aluminum anode for seawater/ pipelines / tanks / boilers / piers
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.
Why choose Aluminum anodes ?
•Aluminum anodes are not so active that they are dangerous in salt or brackish water as are
•Aluminum anodes will last longer because of their increased current capacity.
•Aluminum is the only anode material that can be used safely in all types of water.
•Aluminum anodes are 2 ½ times lighter than zinc making them much easier to carry home from the store!
•Aluminum is a much better alternative than zinc as far as the environment is concerned, since it is not considered a pollutant.
Standard :GB 4948 or America standard
