Bracelet Aluminum Anodes

Menu

Aluminum is the anode of choice for saltwater environments. Engineered aluminum alloys offer relatively low consumption rates of 7 pounds per ampere-year. Aluminum anodes are available in both Mesalum I and Mesalum III alloys. Mesalum I produces an open circuit potential of -1.05 volts (with respect to an Ag/AgCl reference cell) and realizes a 95% current efficiency. Mesalum III generates a voltage potential of -1.15 volts and has a current efficiency of 85%.

Nominal Ampere Hours/Pound=1280 (Mesalum I)

Nominal Efficiency=95% (Mesalum I)

Typical Applications

Offshore bracelet anodes are primarily designed for weld attachment to steel pipes. Mesalum I is not recommended for areas where water flow is restricted. Mesalum III is recommended for any saltwater application but especially in saline mud and lower chloride water environments.
