Zinc Anode 620 Datasheet [Simple]

However, often refers to a common size code in marine or industrial sacrificial zinc anodes. Here is the typical data you'd expect to find for a Zinc Anode, Size 620 (common in hull, rudder, or shaft grounding applications):

💡 Many "620" anodes are rudder or trim tab anodes . Check your part for exact dimensions or an original casting number. zinc anode 620 datasheet

It is designed to meet rigorous military standards (such as ) to ensure it effectively prevents corrosion on steel structures submerged in seawater. However, often refers to a common size code

By acting as a "sacrificial" metal, the 620 anode oxidizes more easily than the steel structure it is protecting. This process ensures that the anode corrodes away while the expensive infrastructure remains intact. Technical Specifications and Chemical Composition It is designed to meet rigorous military standards

No Paint: Never paint over a zinc anode, as this will insulate it and stop the protection process. Maintenance and Replacement
