Difference Between Aluminum Alloy Sacrificial Anode and Zinc Alloy Sacrificial Anode:
The performance of aluminum alloy sacrificial anodes is influenced by the chemical composition of the alloy. We provide different alloy compositions to meet customer requirements and can also manufacture anodes with special chemical compositions based on customer specifications.

Aluminum alloy sacrificial anodes have extremely high electrochemical performance, with a large amount of electricity generated per unit weight of anode material, approximately three times that of zinc anodes and twice that of magnesium anodes. They perform well in seawater and other media containing chloride ions, with strong self-regulating capability for current output.
Aluminum alloy sacrificial anodes are suitable for cathodic protection against metal corrosion in seawater environments, including ships, mechanical equipment, marine engineering, port facilities, as well as pipelines and cables in seabed mud.
Zinc alloy sacrificial anodes have good self-solubility, high current efficiency, and excellent self-regulating performance for current output.
They are suitable for cathodic protection against metal corrosion in seawater and freshwater environments, including ships, mechanical equipment, marine engineering, port facilities, as well as pipelines and cables in low-resistivity soil.

High-efficiency aluminum sacrificial anodes are mostly used for anode protection of metal structures in seawater environments or the bottom plates of crude oil storage tanks and cannot be used in soil environments with low chloride ion content. Their electrode potential is -1.05v CSE. Above 49 degrees Celsius, the electrical capacity decreases with temperature. However, high-efficiency aluminum anodes can be used in soil environments with low chloride ion content.

Potassium, calcium, sodium, magnesium, aluminum, zinc, iron, tin, lead, copper, mercury, silver, platinum, gold—this is the metal activity series. From this, you can see that aluminum is more metallic than zinc. Therefore, in a galvanic cell with the same material as the positive electrode and aluminum or zinc as the negative electrode, aluminum has a stronger ability to lose electrons than zinc, meaning aluminum has stronger reducing properties than zinc. In industry or daily life, the metal to be protected is generally iron, and both can serve a protective role.

Since aluminum is chemically more active than zinc, aluminum anodes have a more negative protection potential, and the unit mass electrical capacity of aluminum anodes is higher than that of zinc electrodes. Generally, aluminum anodes are suitable for media with lower resistance, while zinc anodes are suitable for media with higher resistance. Additionally, the current efficiency of zinc anodes is higher than that of aluminum anodes. Currently, zinc anodes are used in seawater media, aluminum anodes are used in freshwater media, and magnesium anodes are used in soil.
