: Meets British Standard BS 4652 for zinc-rich primers and ISO 12944 Part 2 for environments up to C5.
The metal at risk becomes the cathode and is preserved. The zinc "sacrifices" itself by corroding preferentially, which safeguards the valuable underwater parts of a vessel or structure.
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.
The steel must be completely free of oil, grease, salt, and other contaminants. Any soluble salts on the steel surface should be removed prior to blasting (conductivity should be checked to ensure compliance). Repair/Touch-Up:
Will you be operating primarily in ? Do you prefer a weld-on or bolt-on mounting style? Share public link
The core functionality of the 620 zinc anode relies on its electrochemical performance when submerged in an electrolyte (seawater or brackish water).
Zinc anodes are favored for their stable and predictable performance.
The 620 size classification balances high mass with a relatively low profile, making it highly versatile across multiple sectors: Marine Vessels
Galvanized steel strap (straight or cranked) for welding, or pre-slotted holes for bolt-on applications. Nominal Bolt Centers: 200 mm (for bolt-on variants). 4. Electrochemical Characteristics
To provide you with the exact engineering drawing, could you share the or the specific mounting style (weld-on or bolt-on) you need? Share public link
To ensure reliable performance, high-quality 620 zinc anodes are cast to meet strict international standards, most notably (US Military Specification) or ASTM B418 Type I . These specifications guarantee that the anode will not "passivate" (form an insulating crust) in saltwater.
