Copper wire is a very common type of metal in people's lives and production, playing different roles in different industries. In many industries, in order to improve the performance of copper wire, different metals are plated on its surface to better meet practical application needs. Let's take a look at what changes can occur when different metals are plated on the surface of copper wire.

Nickel plated copper wire

The so-called nickel plated copper wire refers to coating a layer of nickel metal on the surface of the copper wire. The copper wire treated by this type of process will not undergo significant changes in temperature and conductivity of the entire metal, but the biggest difference is that when exposed to air for a long time, the copper wire plated with nickel will have much stronger stability. At the same time, due to the strong passivation ability of nickel based metals, after nickel plating on the surface of copper wire, the hardness of the entire metal will increase, and the acid and alkali corrosion resistance and wear resistance will be greatly improved. The ability of the entire copper wire to adapt to environmental changes will also become stronger.

Silver plated copper wire

This type of copper wire is coated with a layer of silver on its surface. After silver plating on the surface of copper wire, it can effectively reduce the possibility of copper wire being oxidized to form a layer of molybdenum green in the air. At the same time, copper wire itself has poor conductivity. After silver plating on its surface, it can reduce the possibility of oxidation reaction and improve the heat dissipation performance of the entire copper wire. At the same time, it can also effectively prevent the rubber in the insulation layer of the copper wire from sticking and becoming brittle, improving the weldability of the entire copper wire.

Whether it is nickel plated copper wire or silver plated copper wire, compared to pure copper wire, there have been significant improvements in both the usable range and durability, which can bring more possibilities to people's lives and production. This is also an important reason why more and more copper wires are being coated with other types of metal materials on the market.
