Nickel-plated copper wire is a wire that is plated with a layer of nickel substance on the surface of the copper wire by electrolysis, chemical methods, etc. Compared with pure copper wire, the corrosion resistance, wear resistance and hardness of the nickel-plated copper wire have been greatly improved, which can better meet the application in the subsequent parts and improve the life of the parts. Before nickel plating on copper wire, in order to make the entire coating more uniform and meet the requirements, the copper wire needs to be pre-treated and wire drawing treatment.

Silver-plated copper wire is actually a layer of silver metal plated on high purity copper wire, and its electrical conductivity, thermal conductivity and corrosion resistance have been greatly improved, and are widely used in many industries.

It is known that copper wire plays an important role in national production, although the electrical conductivity of gold and silver are as good, but copper is low compared to gold and silver, so it is used in the manufacture of electricity, integrated circuit lead frames, rectifiers, circuit boards, various switches, telecommunications transmission cables and other components. The existing silver plated copper wire is pure copper wire inside, silver plated on the outer surface of the copper wire, although there are certain advantages, but there are disadvantages, silver plated copper wire anti-aging and chemical corrosion resistance is poor, long-term use will affect the conductivity of its own material.
