To ensure the 620 zinc anode operates at peak efficiency, follow these critical deployment rules: Electrical Continuity is Mandatory

| Parameter | Typical value | |-----------|----------------| | Weight | ~0.8–1.2 kg | | Length | 152 mm (6”) | | Width | 51 mm (2”) | | Thickness | 25–32 mm | | Mounting holes | 2 (countersunk) | | Alloy | UNS Z33521 (MIL-A-18001K) | | Capacity | ~780 A·h/kg |

: Ship superstructures, offshore platforms, jetties, and port facilities. Industrial Infrastructure : Pipelines, bridges, and petrochemical plants. Maintenance

The Aluminum and Cadmium act as activators to ensure a uniform, film-free corrosion surface, guaranteeing a driving voltage of approximately 0.25V relative to steel. zinc anode 620 datasheet

: [CITE: 15†L16]

A compliant datasheet will typically specify the following chemical breakdown: Weight Percentage (MIL-SPEC) Purpose / Effect Remainder (approx. 99.1%+) Base metal provider of galvanic current. Aluminum (Al) 0.10% – 0.50% Promotes uniform corrosion and prevents passivation. Cadmium (Cd) 0.025% – 0.07% Aids in shedding the oxide layer to maintain activity. Iron (Fe) 0.005% max Strictly limited; high iron causes quick passivation. Lead (Pb) 0.006% max Impurity control. Copper (Cu) 0.005% max Impurity control. 3. Physical Dimensions and Mechanical Data

Approximately 11.2 kg (24.7 lbs) per Ampere-year. Efficiency: ≥is greater than or equal to 95% in open seawater. 3. Physical and Mechanical Specifications

In conclusion, zinc anodes play a vital role in cathodic protection systems, and the Zinc Anode 620 is a high-performance anode designed for use in various industries. The datasheet provides detailed information on the anode's composition, physical properties, and performance characteristics. By understanding the benefits and applications of zinc anodes, industries can ensure the effective protection of their metal structures from corrosion. Mild steel, galvanized for enhanced electrical bonding To

: Typically 75 microns (can range between 50 and 75 microns). Wet Film Thickness (WFT) : 120 microns. Theoretical Coverage /liter at 75 microns DFT. Finish & Color : Matt finish in Metallic Grey. Heat Resistance : Resists dry heat up to 150°C. www.bergerarabiapc.com Key Applications

Inspect Type 620 anodes every 6 months. Replacement is required when the remaining mass is of original or the steel core is exposed.

The compact profile allows these anodes to be installed within the internal structural ribbing of ballast tanks, preventing localized pitting corrosion caused by stagnant seawater. Installation and Maintenance Best Practices

A surface profile of 50 - 75 microns (Ry5) is recommended to provide sufficient mechanical keying. : [CITE: 15†L16] A compliant datasheet will typically

Used on steel sheet piles, jetty structures, and harbor lock gates.
