Zinc Anode 620 Datasheet

The Zinc Anode 620 is a sacrificial anode designed to protect submerged or buried metallic structures. By possessing a more active (negative) electrochemical potential than the steel or aluminum it protects, the zinc anode corrodes preferentially, safeguarding the primary structure from degradation. Key Applications

Note: Zinc-Carbon anodes degrade faster under heavy load than Alkaline anodes.

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 .

: 75 microns Dry Film Thickness (DFT) / 120 microns Wet Film Thickness (WFT). Theoretical Coverage : Approximately 8.27 m2m squared /liter at 75 microns DFT. Finish & Color : Metallic Grey with a matt finish. VOC Content : 330 g/liter. Application & Performance zinc anode 620 datasheet

6.2 lbs to 7.0 lbs (approx. 2.8 kg to 3.2 kg) — Note: The "620" nomenclature often correlates to its roughly 6-pound class weight.

Installed along the bilge keels or transom of small-to-medium vessels.

The resistance between the anode core and the protected steel structure must be as close to zero as possible (typically less than 0.01 ohms). Ensure welding tabs are clean, or mounting bolts are torqued down securely to bare metal. The Zinc Anode 620 is a sacrificial anode

Poor (Zinc can form a "crust" of oxide that stops the current; use Magnesium instead). If you'd like, I can help you:

When procurement teams request a "Zinc Anode 620," specify the following variables to ensure compatibility:

The Zinc Anode 620 is the industry workhorse for localized protection on steel hulls, sea chests, and side thrusters. When sourcing, demand a verifying the Cadmium (0.07%) and Iron (<0.005%) levels. Standard “Hardware store” zinc will not provide the 780 A·h/kg required for marine service. To perform effectively, a zinc anode must not

For engineers and procurement specialists, the physical specifications are paramount. The ZE-1 "Zinc Anode 620" is a anode, and its dimensions are defined by specific standards.

The "620" designation typically refers to a specific standardized geometry or nominal weight profile used by marine manufacturers. Below are the standard dimensional and physical properties found on a typical 620 zinc anode datasheet. Physical Dimensions
