The reason why the spring is galvanized for corrosion prevention

The reason why the spring is galvanized and corrosion-resistant is that many users like to select galvanized springs when selecting springs. This is certainly not only because the galvanized appearance is more beautiful, but also because the spring steel wire can be prevented from being oxidized and rusted after galvanizing. Now Guoyang Spring will explain the reason why the spring is galvanized and corrosion-resistant in detail.

In the marine or high temperature atmosphere, as well as the spring in contact with seawater, the spring used in 70 ℃ hot water is relatively stable in cadmium and has strong corrosion resistance. Cadmium coating is brighter and more beautiful than zinc coating, soft, better plasticity than zinc coating, and less hydrogen brittleness, which is most suitable for Spring As a protective layer. However, cadmium is rare, expensive, and toxic to the environment. Therefore, the use is limited. Therefore, most springs used in aviation, navigation and electronic industry only use cadmium coating as protective layer.
