Zinc Anode 620 Datasheet | Newest & Trusted

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

Steel must be abrasive blast cleaned to a minimum standard of Sa 2½ (ISO 8501-1) with a surface profile of 50–75 microns . Application Methods:

As a sacrificial anode, it is designed to corrode at a lower electrical potential than the metal structure it protects (such as steel or bronze). By sacrifice, it prevents expensive hull plating, rudders, propeller shafts, and internal piping from pitting and degrading. 2. Chemical Composition Requirements

The designation "620" typically refers to a specific standardized physical mold size or weight classification used by leading marine cathodic hardware manufacturers. zinc anode 620 datasheet

The anode must have a direct, low-resistance metal-to-metal connection to the structure it is protecting. For weld-on variants, the steel straps must be welded directly to the bare metal hull. For bolt-on variants, use clean, unpainted studs, nuts, and tooth lock washers. Never Paint an Anode

-1.05 Volts relative to a Silver/Silver Chloride (Ag/AgCl) reference electrode. Closed Circuit Potential: -1.03 Volts vs. Ag/AgCl.

Minimum 6 - 8 hours; Maximum (Dependent on the specific topcoat, ensure surface is free of zinc salts before overcoating). 4. Surface Preparation Guidelines Maximum (Dependent on the specific topcoat

Submerged protection against brackish or salt ballast water.

What is the total you need to protect?

The ZE-1 anode follows a trapezoidal cross-section design, which improves current distribution and ensures even consumption over its lifetime.

Beyond Deyuan Marine, other manufacturers also use "620" in their product codes. For instance, Taihang Marine uses it in their customizable anode systems, often accompanied by specifications like 620 50 6 8~10 54.5 56.0 , further solidifying its role as a product identifier for a standardized part.

Zinc anodes are highly effective in open seawater and high-salinity brackish water.
