High potential magnesium alloy anodes are made from high purity magnesium alloys with high quality. They are
better suited to dry or resistant soil conditions or where the steel work is poorly coated with other corrosion barriers.
Adopting specialprocessing technology, this anode has excellent electrochemical performance. It produces an open
circuit potential of 1.7V-1.75V with respect to a saturated calomel electrode, so it can provide the most effective
protection for the corroding structures. The high potential magnesium anode is better suited to dry or resistant soil
conditions. Yirui Magnesium provides anodes in a range of sizes with different connections, to suit particular types of structures.
And there are several shapes of magnesium anodes, D type, S type, R type, rectangular, teardrop shapes, ribbon
anodes, etc.. Our high potential magnesium anodes are made to the current ASTM B843 standard. And we can meet your particular
specifications. We guarantee that all of them have the right chemical properties. Chemical Compositions (%):
