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
The Zinc Anode 620 is a reliable and high-performance sacrificial anode used for cathodic protection of steel structures. The datasheet provides essential information about the product's composition, physical properties, and performance characteristics, ensuring that users can select and apply the product correctly. Always consult the manufacturer's datasheet for the most up-to-date and accurate information.
The 620 anode is hard, white, and "crusty" while the steel is corroding. Diagnosis: Passivation. Cause:
In the world of corrosion protection, sacrificial anodes are the first line of defense for metal structures exposed to harsh environments, particularly marine environments. Among the various materials available, high-purity zinc is a preferred choice due to its ideal electrochemical properties. : Contains over 80% zinc by weight in
Never paint the zinc anode. Coating the anode seals the surface and prevents electrical current from flowing. Maintenance and Replacement Inspect anodes during routine dry-docking or dive surveys.
Zinc anodes are optimal for . If your vessel operates primarily in brackish water or freshwater, a 620 zinc anode will quickly form an insulating zinc oxide crust, rendering it inactive. For freshwater or brackish applications, consult an engineering datasheet for aluminum or magnesium alternatives, which offer higher driving potentials. If you need help choosing the right anode, tell me:
: Large hull anodes, such as the NAL 8 model, can have lengths of 620mm and weigh approximately 8kg . Go to product viewer dialog for this item. Zinc Pencil Anode 11 kg (24 lbs) per Amp-year
| Element | Percentage | |---------|------------| | Zinc (Zn) | Balance | | Aluminum (Al) | 0.1 – 0.5% | | Cadmium (Cd) | 0.02 – 0.07% | | Iron (Fe) | ≤ 0.005% | | Lead (Pb) | ≤ 0.006% | | Copper (Cu) | ≤ 0.005% |
, a high-performance epoxy primer, it can also refer to physical dimensions in cathodic protection hardware. Below is an overview of the technical specifications and applications for both interpretations. Zincanode 620 (High-Solids Epoxy Primer) Zincanode 620
The ZE-1 anode follows a trapezoidal cross-section design, which improves current distribution and ensures even consumption over its lifetime.
