Introduction to the advantages and disadvantages of enameled wire:

1. Pure copper enameled wire: including traditional Round Enameled Copper Wire, which has the advantages of wide application range, convenient welding, stable and stable performance, etc. The disadvantage is that the cost is relatively high.
2. Copper-clad aluminum enameled wire: as a substitute for pure copper enameled wire, it has made a difference in terms of saving production costs and good transmission performance. The disadvantage is that the tensile strength is not as good as copper wire, and it is easy to break.
3. Aluminum enameled wire: The advantages of this enameled wire are low density, light weight and saving production material costs. The disadvantage is that the conductor is easy to stretch, not easy to weld directly, and the tensile strength is relatively small.

The main reasons why the enameled wire cannot be soldered to the tin are:

1. The iron tip is oxidized.
2. Since the outer layer of the enameled wire has a layer of grease, it has an insulating effect. Therefore, if you don't remove it, there will be no tinning.
3. The temperature of tin is not enough to melt the paint.
4. The Rectangular Enameled Copper Wireused is not a straight shape, and the enameled wire needs to be scraped off before welding.
