Aluminum Alloy Anode and Screw,125mm Tunnel Thrusters

• The mil-spec alloy includes about 5% Zinc and a trace of Indium to prevent oxidation resulting in a layer reducing the sacrificial properties of the anode.
• Provides more protection and will last longer than zinc anodes of the same size (up to 50% longer).
• Less than half the weight of of a similar sized zinc anode.
• Screw included.
• Provides superior support compared to zinc anodes in fresh or brackish water, while still giving excellent pro­tection in salt water, and is the only anode that is safe for all applications.
