| Element | Percentage (%) – MIL/ASTM Standard | |--------------------|-------------------------------------| | Zinc (Zn) | 99.86% Minimum | | Aluminum (Al) | 0.10% – 0.50% | | Cadmium (Cd) | 0.025% – 0.070% | | Iron (Fe) | 0.003% Max | | Lead (Pb) | 0.003% Max | | Copper (Cu) | 0.002% Max | zinc anode 620 datasheet

While "620" is not a universal standard code, it is a common identifier used by several major manufacturers for a specific family of large-format, high-performance sacrificial anodes. This document consolidates and synthesizes technical data from leading industry sources to provide a comprehensive reference.

If you are searching for "Zinc Anode 620 datasheet," you likely need zinc specifically. Here is the reality check: Efficiency: 90% minimum in standard seawater conditions

Cathodic protection protects metal structures from corrosion. Zinc anodes provide sacrificial protection in marine environments. The serves as a industry standard for hull, tank, and industrial applications. This technical datasheet guide details the composition, physical properties, and performance metrics of the 620 zinc anode specification. 1. Material Composition

The performance of a zinc anode is entirely dependent on its purity. Impurities (iron, copper, lead) cause passivation, where the anode stops working. The Zinc Anode 620 must meet strict limits: etc. | ASTM

| Parameter | Specification (ZE-1 Model) | Specification (ZE-4 Model) | | :--- | :--- | :--- | | | ZE-1 | ZE-4 | | Overall Dimensions (A×(B1+B2)×C) | 500 × (115+135) × 130 mm | 500 × (80+100) × 80 mm | | Iron Foot Size (D) | 620 mm | 620 mm | | Net Weight | ~54.5 kg | ~24.4 kg | | Gross Weight (Incl. packaging/insert) | ~56.0 kg | ~25.0 kg | | Material (Alloy Type) | Zn-Al-Cd Ternary Alloy | Zn-Al-Cd Ternary Alloy | | Mounting Type | Bolt-on / Weldable Steel Core | Bolt-on / Weldable Steel Core | | Shape / Surface | Rectangular / Smooth Cast | Rectangular / Smooth Cast | | Certifications | ASTM, GB, CCS, ABS, BV, etc. | ASTM, GB, CCS, ABS, BV, etc. |

The anode's protective qualities are driven by its fundamental electrochemical properties:

Protects ship hulls, rudders, and propeller shafts.

Sacrificial anodes wear away by design over time. Regular tracking is vital to prevent structural damage.
