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 .

Note: Iron contamination must stay below 0.005% to avoid rapid passivation, which renders the anode inactive. 2. Physical and Dimensions Specifications
Below is a comprehensive technical breakdown of the specifications, applications, and installation guidelines for a standard 620-series zinc anode. ⚓ Zinc Anode 620 Technical Specifications To perform effectively, a zinc anode must not
) used for cathodic protection. These anodes are made of high-purity zinc alloyed with small amounts of aluminum and cadmium to ensure they corrode evenly and don't "passivate" (develop a crust that stops them from working). Key Technical Specifications Based on industry standards like those found on , here is what you can expect from a 620-series datasheet: Potential: Approximately
