Application of zinc anode

The potential difference between zinc anode and steel is about 0.25V, and the potential difference is relatively small, so

In general, it is only used in soil or seawater with soil resistivity less than 152·m, and the maximum resistivity should not exceed 502·m. It can also be used as a ground battery or ground electrode. Whether it is block or strip zinc anode, it should be placed in the filler.

According to different engineering requirements, zinc anodes can be divided into two types: cast (block) and extrusion (zinc strip).

Because the driving voltage of zinc anodes is lower than that of magnesium anodes, zinc anodes are usually used in areas with low soil resistivity, typical application areas include buried pipelines, storage tank walls, etc.
