Zinc: Anode 620 Datasheet

Zincanode 620 is a flammable material and contains high levels of zinc dust. Mixed product is approximately 20°C.

When procurement teams request a "Zinc Anode 620," specify the following variables to ensure compatibility:

If you are looking for the specifications of the battery commonly referred to as the "620":

Proper installation guarantees a low-resistance electrical path between the anode and the structure. Mounting Methods

Sacrificial anodes rely on direct electrical contact with the metal they protect. zinc anode 620 datasheet

~780 Ampere-hours per kilogram (Ah/kg) or ~350 Ah/lb.

Not recommended. In freshwater, zinc forms a hard, impermeable layer of zinc hydroxide (passivation). This stops the current flow entirely, leaving the steel structure unprotected. For freshwater applications, aluminum or magnesium anodes must be specified instead.

Clean the mounting area on the steel structure to bare white metal.

Approximately 2.0 kg to 3.2 kg (4.4 lbs to 7.0 lbs) net zinc weight, exclusive of the steel insert core. 3. Core Insert Variations Zincanode 620 is a flammable material and contains

What is the of your vessel (steel, fiberglass, or aluminum)?

A surface profile of 50 - 75 microns (Ry5) is recommended to provide sufficient mechanical keying.

50 - 75 Microns per coat.

Below is a detailed technical overview based on the standard Berger Zincanode 620 datasheet . In freshwater, zinc forms a hard, impermeable layer

Paint insulates the zinc, preventing it from discharging current and rendering the cathodic protection system useless. Mounting Methods

While "620" in the context of zinc anodes most commonly refers to Zincanode 620

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 is an industry-standard, high-performance solution for corrosion control in marine and industrial applications. By adhering to strict metallurgical standards, these anodes offer long-term protection, ensuring the longevity of expensive steel structures.
