Product Description
Commodity : Cast Marine Sacrificial Aluminum| Zinc Indium Anode for ship
Zinc anodes for commercial or millitary vessels
Application:
Zinc Soil Anodes are used where soil conditions require the use of Zinc Anodes such as saline mud below 120 F (50 C). These anodes would protect objects underground such a storage tanks, containers, and buried structures.
Our anodes are used in recreational , commercial and millitary vessels.
Placed on hulls, propeller shafts, rudders, trimtabs, outboard engines,stem drives, and in coding system of most inboard engines to protect metal parts from galvanic corrosion.

FAQ
Q. What do sacrificial anodes do?
A. All metals immersed in an electrolyte (sea water for example) produce an electrical voltage. When two dissimilar metals are in contact (electrically connected) they produce a galvanic cell (like a battery), with the less noble metal (a bronze propeller for example) forming the anode and the more noble metal (stainless steel shaft) forming the cathode.
Aluminum anode alloy provides more protection and lasts longer than zinc. It will continue to work in freshwater and is safe for use in salt water. Aluminum is the only anode that is safe for all applications.
Q. When we we choose to use Zinc anodes ?
A.
Exterior of underground or underwater pipe
Interior of pipe handling corrosive waters and effluents
Lead sheathed electric cable in ducts
Other metal-sheathed electric cable in underwater or underground locations
Copper concentric neutrals of URD cable
Corrosion control and/or grounding of induced AC on underground pipe
Annulus space between outer steel casing and inner pipe of deep wells
Interior bottoms of oil storage tanks
Foamed annulus space of insulated steel pipe underground or underwater
Double bottom areas of ship ballast tanks
Bottom areas of cargo/ballast tanks of petroleum carriers
