Zinc anodes require high-chloride environments to operate efficiently without passivating.
The Zinc Anode 620 is designed for use in a variety of cathodic protection applications, including:
780 Amp-hours per kilogram (Ah/kg). Consumption Rate: Approx. 11 kg (24 lbs) per Amp-year. Density: 7.13 g/cm³. 🛠️ Key Applications zinc anode 620 datasheet
Understanding physical dimensions and weight ensures proper fitment and adequate galvanic protection lifespan. The "620" designation typically refers to a specific standardized weight or dimensional profile used by marine hardware manufacturers. Physical Dimensions
Suitable for small areas or touch-ups (Pressure: 3 - 4 bar). 11 kg (24 lbs) per Amp-year
The steel core extensions are fillet-welded directly to the steel hull or structure. This guarantees the lowest possible electrical resistance.
-1.05 Volts relative to a Silver/Silver Chloride (Ag/AgCl) reference electrode in seawater. The "620" designation typically refers to a specific
. It is specifically designed for "highly corrosive atmospheres," providing a robust first line of defense for steel superstructures. Key Performance Specs According to the product's official datasheet
