Characteristics of Electro-galvanized Metal Stamping Parts
In order to prevent corrosion, improve the corrosion resistance and service life of parts, and beautify the appearance of products, the metal stamping products are electro-galvanized.
Because zinc is not easy to change in dry air, and can also produce a basic zinc carbonate film in a humid environment, this film can protect internal parts from corrosion damage, even if the zinc layer is damaged by some factors, zinc Combined with steel over a period of time forms a microbattery that protects the steel substrate as a cathode.
The advantages of electro-galvanizing of stamping parts:
1. Good corrosion resistance, meticulous and uniform combination, not easy to be entered by corrosive gas or liquid.
2. Because the zinc layer is relatively pure, it is not easy to be corroded under the acid or alkali environment. Effectively protect the steel body for a long time.
3. The zinc coating has good ductility and will not easily fall off during various bending, handling and impact processes.
4. After passivation by chromic acid, it can be used in various colors, which can be selected according to customers' preferences. The galvanizing is elegant and decorative.
