Aluminum Flanged Anode is an aluminum-based sacrificial anode specifically designed for low-current cathodic protection requirements of large storage tanks. The anode features an aluminum-zinc-indium (Al-Zn-In) alloy formulation, providing a stable operating potential and a current efficiency of up to 90%. It is suitable for corrosion protection of tank inner walls, bottom sediments, and water phase areas.
