Aluminum anodes are special devices used to protect submerged structures, like boat hulls, from corrosion. They are made from an aluminum alloy that is very efficient, especially in seawater. These anodes come in many shapes and sizes and can be mounted in various ways to fit different needs.
Customization
Aluminum anodes can be customized to meet almost any requirement.
Type Approval
The aluminum alloy used in these anodes meets the DNV class program DNV-CP-0107 for sacrificial anode materials, following Det Norske Veritas’ Recommended Practices, DNV-RP-B401. They can also be provided according to NORSOK M-503 and other standards upon request.
Current Capacity
After 12 months of testing, the mean current capacity of these anodes is 2,651 Ah/kg. The mean closed circuit potential is -1,100 mV versus Ag/AgCl seawater.
