La description
Zinc Alloy Galvanic Ship Hull Anode
Zinc Alloy Galvanic Ship Hull Anode
♦ Caractéristiques
Zinc Alloy Anode are cast from high grade zinc alloyed to ensure an even corrosion pattern, reliable electrical efficiency and long working life. The anodes are made to meet ASTM B418 type I standard and U.S. MIL-A-18001K.
zinc anode’s protective properties result from a strongly negative reduction potential, which is more negative than the metal it is protecting. Oxidants, which corrode metals, will oxidize the zinc anode rather than the protected metal structure, thus preventing the structure from being corroded.
♦ Application :
zinc anodes are recommended for salt water applications, the most common usage is found in marine applications such as on boat hulls, tanks, rudders and piers. They are also commonly used for underground tanks and piping.
Zinc anodes corrode much more easily than the materials they are protecting, drawing the corrosion away from equipment.
♦ Chemical compositions of Zinc Anode :
Taper | Al % | Cd | Fe % | Pb % | Cu % | Zn. |

Q.What information will be needed if I want a quotation?
UN: Materials contents(Chemical Compositions) and the size of models. Special structures with drawing, Qty and delivery time.
Q. Can we visit your company/factory before place the order?
UN: Welcome to visit us in China. Hopefully it will be a happy journey here.
Q: Comment fonctionne votre usine en matière de contrôle de la qualité?
UN: Quality is base of the company life. We working on new materials industrial for more than 20 années.
Q. What do Magnesium sacrificial anodes do?
UN. Magnesium anode is used in the technical method of electrochemistry cathode protection. theory is from that connect with the protected metal body ,with the exhausting and dissolving of negative metal material or alloy ,protective curer body will be protected from corrosion . Mg anode can produce higher quality potential power, is ideal sacrificial materials.
