A method for distinguishing copper wire of good quality

Copper wire has a good conductivity, so the application is very extensive,we know that the types of copper wire is also very rich, copper wire, copper clad wire, and so on.The quality of copper wire has its pros and cons, to teach you some simple identification methods.

Firstly, observe the surface of bare copper wire. If there is some phenomenon of bending and unevenness, it feels rough. In this case, the quality of copper wire is problematic, which may be caused in the production process.Then observe the flash problem of bare copper wire. If there are some reflective spots on the surface, the surface of copper wire is damaged, which may be caused in the process of drawing, indicating that the quality of copper wire is not good.If the copper wire produced has such a situation, it should pay attention to check whether the mold has been worn, whether the guide wheel has been used for a long time is not flexible, these may lead to flash problem.

If there are some smile on the surface of copper wire, the visual finish is very poor, this phenomenon is called hair, but also because of wear and tear, there are some abrasions and other problems, that copper wire quality is not excellent.From the appearance can roughly observe the quality of copper wire, so we must open our eyes when buying copper wire, do not be confused by inferior products.
