Frequently Asked Questions
Which standard covers magnesium sacrificial anodes?
ASTM B843 is the governing specification. CathPro manufactures both grades under it: standard-potential AZ63B (H-1) and high-potential M1C.
What is the difference between standard-potential and high-potential magnesium anodes?
Standard-potential AZ63B contains about 90% magnesium, 6% aluminum and 3% zinc and is commonly used in lower-resistivity soils. High-potential M1C is made from high-purity magnesium with a more negative driving potential (about −1.7 V), so it is selected for higher-resistivity soils and more demanding environments.
Are prepackaged magnesium anodes available?
Yes. Anodes can be supplied prepackaged in a permeable cloth bag with prepared backfill and factory-attached lead wire, ready for direct installation in soil.
Can magnesium anodes be produced in custom weights and dimensions?
Yes. Standard American weights are available from stock patterns, and non-standard anodes are cast to the customer drawing, including core and insert configuration.
What documents are provided with a magnesium anode order?
Certificate of analysis (COA), material test certificate (MTC) and certificate of origin are issued as standard, with third-party inspection (SGS, BV or a client-nominated agency) available when specified at order stage.
How do I request a magnesium anode quotation?
Start with a drawing, photo or a short description by WhatsApp or email. You can add the alloy grade, weight, quantity, required documents and destination later. We can discuss the remaining specifications with you before preparing a quotation.
