Copper wire has a good solderability and corrosion resistance, typically used for high current applications. Also used for tying, forming parts, and grounding applications.

Copper wire has the best electrical conductivity after silver. As silver cannot be afforded in a wide variety of things, it is copper wire which is very widely used. Due to the high ductile strength of copper, it can be transformed into a strong wire. According to research conducted by scientists at various colleges, a 4 inch thick copper bar can be heated and pulled into a 20 million times long wire than the size of the copper bar which will be thinner than the human hair strand. Hence, we can say that the copper is one of the best metals to be used in the form of a wire.

Copper wires can be divided into plain copper wires, tin coated copper wires and braided copper wires. Plain copper wire is used in electronic items to make point to point connection on the printed circuit board, for electric connection in train and trolleys, etc. Tin coated copper wire has almost the same applications like the plain copper wires. The only difference is that the tin coating prevents the copper wire from eroding or oxidizing. Braided copper wires are used at the places where flexibility is required. It is used in the headphone cables, speaker wires, etc. info from science struck.

Copper wires are used in a variety of applications. Following are some of the most common uses of copper wire which will help you to understand the necessity of this metal.
