Imtra Corporation Side-Power Aluminum Alloy Anode & Screw
Imtra Corporation Side-Power Aluminum Alloy Anode & Screw. The alloy used in Al-Zn-In anodes is quite different to normal aluminum. 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. The Al-Zn-In alloy anodes provides more protection and will last longer than zinc anodes of the same size (up to 50% longer). Another benefit of Al-Zn-In anodes is that their weight is under half the weight of a similar sized zinc anode. The anodes will provide superior support compared to zinc anodes in fresh or brackish water, while still giving excellent protection in salt water - the Al-Zn-In alloy anode is in fact the only anode that is safe for all applications.Includes: Securing ScrewFits Models: SH1000, SAC513, SH1400 and SAC610 Thrusters
