Specifications

?carry out standard ASTM-98 ; high potential anode
?fine performance
?factory direct

High potential magnesium anode in conform to the standard ASTM-98is made from high purity magnesium with high quality. The anode adopting special technique holds splendid electrochemistry performance. In the process of cathode protection, anode consumption is stable; therefore, it has longer life time. In the actual used process, the actual measurement working potential is between-1.8v and 1.85v; therefore, it can provide the most effective protection for structures. It is suggested to use potential magnesium anode in the soil whose resistance is over 8000ohm.cm.
