Single-Strap Straight Aluminum Hull Anode
Our corrosion-resistant hull anodes protect ships from seawater and moisture, safeguarding the vessel’s main body and machinery from deterioration.
Description
Ships constantly face corrosion challenges due to water and moist winds. Our lightweight, high-amperage output straight aluminum hull anode is designed to combat this, offering exceptional protection to oceangoing vessel hulls. Its galvanized steel core enables direct welding to safeguarded steel structures for a secure connection.
Quality Substrate Material
Crafted from top-grade materials, our aluminum hull anode complies with GS EP COR 201 standards. Its lifespan significantly surpasses that of competitors.

Low Driving Voltage
Our aluminum hull anode maintains consistent performance in saltwater and brackish/estuarine environments due to its operating potential range of -1.05 to -1.10 volts relative to the saturated calomel electrode (SCE).
Technical Measurement | Performance |
---|---|
Open Circuit Voltage (-V) | 1.10 min. |
Closed Circuit Voltage (-V) | 1.05 min. |
Current Capacity | 1135 A.h/lbs (2500 A.h/kg) |
Current Efficiency | 90% min. |
Consumption Rate | 7.6 lbs/A·y (3.4 kg/A·y) |
Much Lighter in Weight
Aluminum hull anodes are lighter and easier to handle during fitting compared to zinc due to their lower density.
Strict Quality Control
Our aluminum hull anode is produced, inspected, and tested to stringent standards under ISO 9001:2015 guidelines, ensuring exceptional quality.
