Galvanized copper wire has the basic special galvanized wire. It just doesn't oxidize. It's protective. There is galvanized copper wire after its resistance will be small. On the metal not only copper galvanized, but also other metal galvanized, the surface of other materials coated with a layer of zinc to play a beautiful, rustproof and other effects of surface treatment technology. Most of the metal materials are mainly hot-dip galvanized method.

Zinc chemistry I is soluble in acid, can also be soluble in alkali, so it is called amphoteric metal, Adiwang in the air is not easy to oxidize the role, in the humid air, zinc surface will form a dense basic zinc carbonate film. In sulfur dioxide, hydrogen sulfide and Marine atmosphere, zinc corrosion resistance is poor, especially in high temperature and high humidity containing organic acid atmosphere, zinc coating is extremely easy to be corroded. The standard electrode potential of zinc is -0.76V, for the steel substrate, zinc coating is anodic coating, it is mainly used to prevent corrosion of steel, and its protective performance is closely related to the thickness of the coating. These are used to make zinc coating after passivation treatment, dyeing or coating light protection agent, can significantly improve its protective and decorative, galvanized line effect in the market there are a lot of applications.
