Aluminum alloy sacrificial anode electrode voltage is generally between -0.75 ~ -1.30V (SHE), the current efficiency is between 95% (including Hg alloy) and 70% ~ 80% (including Cd, In, Sn alloy). Adding two or more alloying elements to aluminum can greatly improve the performance of the sacrificial anode, which can not only make the voltage negative enough, but also make the current efficiency reach a high degree.

Avoid collision with steel structure; Not recommended for use in soil.

It is not recommended for use in soil, mainly because the corrosion products generated on its surface are difficult to migrate in time in the soil, and it is easy to form a solid product film wrapped around the anode, causing difficulty in current generation, and may make the cathodic protection ineffective.

Libo anti-corrosion aluminium alloy sacrificial anodes protect against corrosion of steel structures in seawater. It is suitable for cathodic protection against metal corrosion of ships, machinery and equipment, Marine engineering and port facilities in seawater medium and pipelines and cables in sea mud
