>>> Mg Low Potential Anode

H-1 Alloys are made to meet ASTM Standard, Alloy AZ63. This unique composition allows for even current output. In low resistivity soil (under 2,000 ohm/cm), we suggest to use our low potential magnesium anodes, because low potential magnesium anodes are more economical than high potential magnesium anodes.
