MORE ABOUT ALUMINUM ANODES
With relatively low pricing potential, low consumption rate and high current efficiency, aluminum alloy anodes are best suited to seawater applications.

The performance of aluminum alloy anodes in seawater and electrolytes containing chloride ions provides a stable solution as its operating potential is kept between -0.95V to -1.10V (to a saturated calomel reference electrode).

 Relatively low driving potential and high current capacity per unit extends aluminum life expectancy in this application.
