Magnesium sacrificial anodes for cathodic protection.
High-potential and standard-potential anodes for buried pipelines, storage tanks, heat exchangers and water heaters.
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.
What this material delivers in production.
High-potential grade
M1C alloy delivers −1.75 V (CSE) for high-resistivity soils.
Standard-potential grade
AZ63 alloy for general buried and immersed service.
Multiple formats
D-shape, trapezoid, rod, ribbon and water-heater anodes.
Backfill packaging
Pre-bagged gypsum/bentonite/sodium-sulphate backfill on request.
Cable assemblies
Factory-fitted cable, lug and resin seal to customer drawing.
Standards compliance
Produced and tested to ASTM B843 and ASTM G97.
