Selection and Purchasing Review
A magnesium sacrificial anode provides cathodic protection by consuming preferentially while connected to a steel structure. Selection should not be based on weight alone; the protected structure, electrolyte, resistivity, installation, target life and connection design must be considered. The listed material system uses Mg-6Al-3Zn as a primary reference, with final dimensions and configuration confirmed by project.
Information to include with an RFQ
- Water heater, tank, pipeline or other protected structure
- Electrolyte, temperature, resistivity, soil or water conditions
- Anode dimensions, shape, steel core and connection drawing
- Target protection life, installation space and replacement method
- Quantity, inspection, packaging and schedule requirements
Engineering confirmation
Anode quantity, distribution and expected life should be calculated by qualified project personnel from actual site parameters. Product specification must align with cathodic-protection design, installation and monitoring requirements.
Submit the application and design conditions for material, configuration, supply and quotation guidance.

FAQ
How does a magnesium sacrificial anode prevent corrosion?
Magnesium has a more negative potential and preferentially consumes in a suitable electrolyte, helping provide cathodic protection to the connected steel structure.
Where is an Mg-6Al-3Zn anode commonly evaluated?
Listed directions include water heaters, buried tanks, pipelines and related engineering corrosion-control applications. Suitability must still be checked against electrolyte, resistivity and protection design.
How are anode size and expected life determined?
Size, quantity and life depend on protected area, current demand, electrolyte, resistivity, anode efficiency and installation conditions, and should be calculated from project data.
Can the steel core and connection be customized?
Anode shape, steel core and connection can be evaluated from drawings. Include installation space, mechanical loading and electrical-connection requirements.
What information is needed for quotation?
Provide the protected structure, electrolyte, environment data, target life, dimensional and connection drawing, quantity, inspection standard and installation conditions.
