H-1 ALLOY CAST MAGNESIUM ANODES

Supplying Cost Effective Protection
Electrolytic conditions in the soil surrounding a buried structure often determine the type of anodes employed in a cathodic protection system. In lowresistivity soil (under 2000 ohm-cm), Corrpro’s H-1 line of magnesium anodes are the most economical choice. Corrpro Certified H-1 anodes are cast to meet American Society for Testing Materials Standard B80, Alloy AZ63. This unique composition allows for even-current output and efficient protection. The anodes are supplied in three quality grades, all of which produce an open circuit potential of 1.53- 1.55 volts.
Special procedures are also employed in the production of the Certified H-1 anodes to ensure long-life performance. Lead wires on all three grades of anodes are silver soldered and then potted with a sealant to prevent the intrusion of moisture.

Typical Applications
H-1 anodes are recommended for use in low-resistivity soils (typically below 2000 ohm-cm). Because the anodes have a lower driving voltage than high-potential anodes, they are ideally suited for structures where over protection is of concern. Their lowercurrent output also allows these anodes to operate longer than their high-potential counterparts in more conductive environments.
