In seawater and chloride-containing media, it has good performance and strong self-regulation ability of current.
Function: Aluminum alloy sacrificial anode has excellent electrochemical function and large power generation per unit weight of anode material, which is about 3 times that of zinc anode and 2 times that of magnesium anode.
Sacrificial anodes for hull cathodic protection are divided into three categories, including single iron foot welded sacrificial anode, double iron foot welded sacrificial anode, and bolted sacrificial anode.
Classification of aluminum anodes: Sacrificial anodes are divided into five categories according to their materials, including aluminum-zinc-indium-cadmium alloy sacrificial anode, aluminum-zinc-indium-tin alloy sacrificial anode, aluminum-zinc-indium-silicon alloy sacrificial anode, aluminum-zinc-indium-tin-magnesium alloy sacrificial anode, and aluminum-zinc-indium-magnesium-titanium alloy sacrificial anode.
Main uses and scope of use: Aluminum anodes are suitable for cathodic protection of metal corrosion in ships, mechanical equipment, ballast tanks, inner walls of storage tanks, coastal facilities, submarine pipelines, dock steel piles, offshore platforms, cables and other facilities in seawater media.
