Top Benefits and Advantages of Copper Wire

Posted By xinyuwire winding     May 20, 2021    

Copper wire is largely used these days and will still be used for a long time in the future. Maybe most of us don’t know what the reasons are. Here let’s summarize its advantages together.


Copper is one of the most conductive materials of electricity available. It stands only second to silver in the line up of metals. Therefore, it’s no surprise that it is regularly used in and alongside machinery that requires a reliable electrical connection. In contrast to other options, it can be used with less insulation and armoring, allowing you to be flexible with your set-up.

Heat Resistance

Another key benefit of copper wire is it’s resistance to heat. On the contrary, it is a good conductor of heat and can be used in appliances where it needs reliable corrosion protection. It also has a high melting point, offering longevity over the years.


Malleability is a material’s ability to be shaped into the desired shape without breaking. Copper has a high malleability rating. This allows it to be hammered or rolled into sheets or bent into any direction without the risk of snapping. In electrical settings, the thick wires can be twisted around corners or moulded to fit the available space exactly.


Ductility is a material’s ability to withstand high tensile stress. This is any force that pulls two ends of the material away from each other. This is how copper wires are made – the material is stretched into a thin wire. And, for professional use, these wires need to maintain their strength without becoming brittle. And now, the Cons.

Small Amounts of Electricity

Although copper wires are excellent conductors, it does not perform very well when handling very exact amounts of small electrical charges. Copper wires are usually not used in high-tech automotive parts and semiconductors because of its inability to control electrical surges. Manufacturers and makers of semiconductors often use silver and gold wires in these applications because these metals are more stable when handling small amounts of electricity, ensuring no electrical surges destroy sensitive components.

Electromagnetic Interference

Copper wire is susceptible to electromagnetic interference, potentially leading to some devices working improperly. Applications that require connection stability, especially in communication, often experience issues when copper wires are used because of this disadvantage. Manufacturers of communication devices prefer using optical fibers, which are unaffected by electromagnetic interference, as opposed to copper wire.
