Aluminum alloy sacrifice anode
Performance: Aluminum alloy sacrificial anode has very high electrochemical performance, the anode material per unit weight of the energy generation, about three times as much as zinc anode, magnesium anode twice. In seawater and chloride ion containing medium, the performance is good, the self-regulation ability of electric current is strong.

Performance Category Indicators | The open circuit potential-V(SCE) | Work potential-V(SCE) | Actual capacitanceA·h/kg | Current efficiency% | soluble |
Ordinary aluminum anode | 1.10-1.18 | 1.05-1.12 | ≥2400 | ≥85 | The corrosion products are easy to fall off and the surface dissolution is uniform. |
High efficiency aluminum anode | 1.10-1.18 | 1.05-1.12 | ≥2600 | ≥90 | |
Highly activated aluminum anode | 1.45-1.50 | 1.40-1.45 | ≥2080 | ≥70 |
Main application and scope of use: aluminum anode is suitable for cathodic protection of metal corrosion protection of ships, machinery and equipment, ballast water tanks, inner wall of storage tanks, coastal facilities, submarine pipelines, wharf steel piles, offshore platforms, cables and other facilities in seawater medium.
Classification of aluminum anodes: Sacrificial anodes are divided into five types according to their materials, including al-Zn-indium-Cadmium alloy sacrificial anodes, al-Zn-indium-tin alloy sacrificial anodes, al-Zn-indium-tin-magnesium alloy sacrificial anodes, and al-Zn-indium-magnesium-titanium alloy sacrificial anodes. There are three types of sacrificial anodes for hull cathodic protection, including the welded sacrificial anodes, the double welded sacrificial anodes and the bolted sacrificial anodes.
