Therefore, when zinc reaches saturation in the solid melt, the two elements of zinc and iron atoms diffuse with each other, and the zinc atoms diffused into (or infiltrated into) the iron matrix migrate in the lattice of the matrix and gradually form an alloy with iron, while the iron diffused into the molten zinc liquid forms an intermetallic compound FeZn13 with zinc and sinks into the bottom of the hot-dip galvanized pot, that is, zinc slag. When the workpiece is removed from the zinc leaching solution, the surface of the pure zinc layer is formed, which is hexagonal crystal, and its iron content is not more than 0.003%.

The price of galvanized iron wire performance is the key to win, galvanized wire only with good performance, in order to win the market, in order to obtain customer praise. In galvanized wire, the main function of carbon in increasing hardness, less is less easy to rust, the main function of chromium is acid and alkali resistance; Nickel’s main function is high temperature resistance, acid and alkali resistance and conductive use; The main function of iron is magnetic conductivity; The main functions of titanium are low density, high hardness and strong corrosion resistance. The main function of copper is magnetic and electrical conductivity. Different chemical components have different functions, which together form the characteristics of galvanized wire.
