When procurement teams request a "Zinc Anode 620," specify the following variables to ensure compatibility:
To provide more tailored technical data, could you specify or alloy standard you are targeting, or let me know the exact mounting configuration (weld-on or bolt-on) required for your project? Share public link
To perform effectively, a zinc anode must not passivate—a process where a tightly adhering crust of corrosion products forms on the anode, stopping it from wasting away and halting protection. High-quality 620 anodes are manufactured to strict military or international standards, most notably (formerly MIL-A-18001K) or ASTM B418 Type I . zinc anode 620 datasheet
Choose zinc ONLY for saltwater/brackish water. Do not use zinc in low-temperature fresh water or in high-sulfide muds.

The Type 620 is typically welded or bolted to the ship’s side frames or keel cooler.
Designed for operating temperatures under 50°C (122°F). At temperatures exceeding 60°C (140°F), zinc undergoes a potential reversal, becoming cathodic to steel, which accelerates the destruction of the steel structure. Typical Use Cases Ship hulls and thruster tunnels. Ballast tanks and sea chests. Offshore drilling platforms and jackets. Harbor piers, pilings, and lock gates. 5.
