Magnesium Materials

Magnesium sacrificial anodes for cathodic protection.

High-potential and standard-potential anodes for buried pipelines, storage tanks, heat exchangers and water heaters.

Product introduction

Magnesium Sacrificial Anodes

Magnesium anodes protect steel structures by corroding preferentially, and remain the most widely used galvanic anode in soil and fresh-water service.

CHM produces both high-potential (M1C) and standard-potential (AZ63) anodes, cast with steel cores or extruded as ribbon for long linear structures.

Anodes are supplied bare or pre-packaged in backfill bags with cable and connection hardware fitted to your specification.
