Other Specification : Zinc Anodes, Aluminum Anodes & Magnesium Anodes Which Anode Material Is Used For What Application? ZINC Anodes # For Use In Salt Water Only # Not Recommended For Use In Fresh Water ALUMINUM Anodes # For Use In Salt And Brackish Water # Not Recommended For Use In Fresh Water # Proven To Last Longer Than Zinc Due To Increased Capacity MAGNESIUM Anodes # For Use In Fresh Water Only # Not Recommended For Use In Salt And Brackish Water # The Only Alloy Proven To Protect Your Boat In Feresh Water Sacrificial Anodes Are Placed On Hulls, Propeller Shafts, Rudders, Trim Tabs, Outboard Engines, Stern Drives, And In The Cooling System Of Most Inboard Engines To Protect Metal Parts From Galvanic Corrosion. Galvanic Corrosion Occurs When Dissimilar Metals, Such As An Aluminum Stern Drive And A Bronze Through-hull, Are Placed In An Electrolyte Solution Such As Seawater. Dissimilar Metals Are Those Metals Which Have Different Corrosion Potential (measured In Volts) As Determined By The Galvanic Series, And The Most Common Scenario In Boating Is Current Passing From The More Noble Bronze To The Less Noble Aluminum. This Transfer Of Current Results In Deterioration Of The Less Noble Metal. The Addition Of A Zinc Actually Increases Current Activity Between The Metals, But Because Zinc Is The Least Noble Of The Three Metals In This Example, Corrosion Damage Is Primarily Confined To The Zinc Itself When Properly Installed. Marine Anodes Are Available In Zinc, Aluminum And Magnesium Metals To Protect Different Hardware Items And Other Metal Boat Components.
