Many people buy enameled copper wire to use, but are not sure if the copper core in the purchased copper wire is real. Today I will teach you a few ways to distinguish the true and false copper cores. The first method is that copper as a conductor is very resistant to high temperature. It can be burned with fire. If it can withstand high temperature, it must be real copper. The second method, friends who like to do handicrafts must have sandpaper at home. You can take a piece of fine sandpaper and gently polish the identified copper wire a few times. If the rose red is exposed, it is copper. Other colors All are different types of copper alloys. In order to judge the correctness of the color, you can first find an enameled wire or wire sand to have a look, it is all copper rather than copper alloy. The last method is very simple. There is a mark on the insulation layer of the real wire. After getting the enameled copper wire, you can see if it indicates the material of the conductor, which is real copper instead of copper alloy. Copper is softer and has a larger elongation, while copper alloys are harder and have a slightly smaller elongation. The above are some simple and daily methods of identifying enameled copper wires, which are both efficient and professional. You can try them.
