Rectangular Aluminum Hull Anode with Double Straps

The ship is continuously in contact with water and moisture-laden winds which makes it highly susceptible to corrosion. Corrosion is one of the greatest enemies of the ship main body and its machinery —— from the outer body (mainly hull) to the smallest equipment used in operations.

Characterized by lightweight and high amperage output, this rectangular aluminium hull anode will provide excellent protection for the hull on ocean-going vessels. The cast-in galvanized steel core allows for direct welding to the protected steel structure ensuring a reliable connection.

Low Driving Voltage
This aluminium hul anode provides a stable performance in salt and brackish/estuarine waters as its operating potential is kept between -1.05 to -1.10 volts relative to 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
The aluminium hull anode is less dense than zinc, making it lighter and easier for handling when fitting.

Strict Quality Control
By conforming to ISO 9001:2015 standards, our aluminium hull anode is manufactured, inspected, and tested in accordance with stringent procedures to ensure high quality.

Customized Configurations
A range of standard anode sizes are illustrated below. Custom-made shapes, weights, and core configurations are available upon request.
