How to choose the plating metal of the terminal at the conductor part?

The electroplating process plays an irreplaceable role in both daily life and industrial production. For example, the tableware we use every day, basically all metal products adopt the electroplating process, and the biggest role of electroplating should be Anti-rust, if the inert metal is directly plated on the component, it can slow down the overall oxidation rate and properly protect it.
However, in the industrial wiring industry, electroplating is also used on the terminals of the wiring, but how should we choose the metal for the plating? Then we should first understand the main function and purpose of electroplating. If it is only for anti-rust, then screws are usually selected as the main iron products, so its role in anti-rust is particularly important. In the entire market, anti-rust Electroplating mainly includes nickel plating, silver plating, tin plating and galvanizing, etc., because the metal of the coating cannot directly change the properties of the material. If the conductor in the middle needs to be energized, the metal of the coating cannot be used for it change in conductivity.
This electroplating process can make the terminal look thicker or more eye-catching than the screw under the same situation, and it also improves the appearance of the terminal a lot, but there is nothing in the overall performance. The change, and then let the screw directly lock the part of the conductor to the bottom. Other conductor parts need to be silver-plated. In fact, the electroplating of the end is still more important. The main reason is that the conductor needs to be energized, and silver-plated The biggest advantage is the reduced resistance of the contacts.
