Zinc Anode 620 Datasheet ((exclusive)) Direct

I couldn’t find an official or universal datasheet for a "Zinc Anode 620" because that part number isn't a standard industry designation across major marine or cathodic protection brands (e.g., Martyr, Cambrian, MG Duff, Galvotec).

🔹 Applications

  • Boat hulls (outboard/inboard engines)
  • Shafts and rudders
  • Heat exchangers
  • Pipe flanges and tank interiors
  • Seawater cooling systems

Always ensure a metal-to-metal connection. Never paint over your zincs, as this effectively "insulates" them and stops the protection. Placement: For vessels, BoatCorrosion.com zinc anode 620 datasheet

For maximum efficacy, proper surface preparation and application conditions are critical. I couldn’t find an official or universal datasheet

2. Chemical Composition (Per ASTM B418 Type I & II)

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: Always ensure a metal-to-metal connection

  1. Seawater applications: Offshore platforms, pipelines, and coastal structures.
  2. Brackish water applications: River estuaries, tidal zones, and freshwater/saltwater mixing areas.
  3. Soil applications: Buried pipelines, storage tanks, and other underground structures.
  1. Oil and Gas: Zinc anodes are used to protect pipelines, storage tanks, and offshore platforms from corrosion.
  2. Marine: Zinc anodes are used to protect ships, boats, and other marine structures from corrosion caused by seawater.
  3. Construction: Zinc anodes are used to protect reinforced concrete structures, such as bridges, buildings, and highways, from corrosion.

The Zinc Anode 620 has the following performance characteristics:
