Copper Wire

Copper is a metal and is used in making electrical equipments and electronics gadgets. The main use of copper is in making electrical wires because it is a good conductor of electricity. It is a type of a metal containing many mixtures. The purity of copper varies and there is a type which is called cadmium free copper, also known as “Electrolyte Copper”. This is 100 % pure variety.
Bare copper wire has a complex shape and is made into cables. It is used as overhead electricity source for heavy and light transit systems, subways, electrically run mine trains, buses, and the industrial cranes. The copper wire manufacture do involve some stages which later on shift in different directions depending on the use it is supposed to be put in. The copper wire manufacturers have to convert the raw copper rod extracted from its ore and take it through some processes that are involved in their manufacturing.
First of all, Continuous Cast Copper rods of a specified diameter are put into wire drawing and this drawn wire is made into different kind of wire gauges.
After completing this drawing process, the now underprepared wires are kept in an Electric Furnace pot for getting it converted into soft wires of copper. This process is called annealing of the wire.
After the process of annealing of the wires is complete, the process of bunching and stranding of these wires is starts. There are machines which aid in making different sizes of stranded and bunched wires which are still raw and unfit for commercial use as the last step is yet to be taken. The nozzling of these wires is undertaken to prepare the surface of wires better for the next process.
The next step in copper wire manufacture is the Tinning Process. It can be done through either Hot dip process or through Electroplating. In the Hot dip process of copper wire manufacture, the tin is prepared into what is called pickled tin and wire is passed through this. This gives the wires a coating. They are then wound on reels.

The next step in copper wire manufacture is braiding. The braided copper wires are essential for many processes. The copper wire manufacture process is almost complete now but braiding or twisting the wires in order to make braided copper wires according to specifications is important as only then it can be put to different uses. Only braided copper wires become useful for commercial use.

The process for tinsel wires of copper is slightly different. It involves a flattening process, a nylon lapping process, but then again it is put in braiding machines. These slightly different braided copper wires are put to different use which non-tinsel wires cannot accomplish. In the end of every process braided copper wires is the result.
Another process for this metal is where a glass coating is provided to the copper wire. Even in this process, braided copper wires are the end result as the last step is braiding of wires.
