The use of extruded anodes for cathodic protection of residential and commercial glass-lined water heaters is a common practice. Mag Specialties supplies customers with both magnesium and aluminum anodes. Our magnesium anodes consist of our standard Galvorod™ (AZ31B) for regular application or Galvomag™ (M1C) for high-current output applications. Both magnesium and aluminum anodes (A420 & A8020) can be supplied in a variety of sizes and finishes.
Some of the benefits of our anodes are listed below:
Guaranteed highest quality
We supply the highest quality anodes verified by independent labs
High anode efficiency
Extruded anodes typically have a 54% anode efficiency or higher per ASTM G97 test ensuring they will last over extended periods of time
NSF/ANSI 61 Certification
MAG is NSF/ANSI 61 certified, ensuring our anodes have been tested for trace elements that may be harmful
Galvoline™ product line, also an M1C alloy, is primarily used for underground applications with high current output requirements. Galvoline™, unlike individual anodes, produces an efficient and even current distribution along a pipeline. This product line is typically sold in coils and delivered on pallets.
