High potential magnesium anode

1 The product introduction

High-potential magnesium anodes are produced using high-quality and high-purity magnesium, and the products comply with ASTM97-98 standards. Using a specific process, the anode has excellent electrochemical performance. In the cathodic protection process, anode consumption is even, so it has a longer service life. In actual use, the actual measured working potential is between -1.8V and -1.85V, so the target structure can provide the most effective protection. It is recommended to use high-potential magnesium anode in soil with resistivity greater than 8000Ω.m.
