Key Advantages and Disadvantages of Copper Wire

Copper wires can be found in almost any electrical or electronic device. In addition, copper wire has numerous advantages, making it one of the most widely used electrical wires on the planet.

Fremont, CA:  Some materials outperform copper, such as fiber optics, resulting in several significant competitors to copper wire.

Heat Resistance and Conductivity

Copper wires are only second to silver in terms of electrical conductivity. Copper wires can handle a more significant electrical power load than other non-precious metals, allowing for less insulation and armoring. They have a high heat resistance, which eliminates most overloading issues. Copper wires are also corrosion-resistant. Despite the presence of patina, a tarnish caused by oxidation, the material will retain its functionality.

Ductility and malleability

Copper has high ductility, allowing for wires as thin as human hair strands. Its malleability allows it to be bent into nearly any shape without breaking. Copper is used to make thick electrical cable wires within electrical posts and applications that require very thin wires.

Electricity in Small Amounts

Although copper wires are excellent conductors, they do not perform well when handling minimal electrical charges. Because of their inability to control electrical surges, copper wires are typically not used in high-tech automotive parts and semiconductors. Instead, semiconductor manufacturers and makers frequently use silver and gold wires in these applications because these metals are more stable when handling small amounts of electricity, ensuring that no electrical surges destroy sensitive components.

Interference with Electromagnetic Fields

Copper wire is susceptible to electromagnetic interference, which could cause some devices to malfunction. Because of this disadvantage, applications requiring connection stability, particularly communication, frequently encounter problems when copper wires are used. As a result, manufacturers of communication devices prefer to use optical fibers, which are unaffected by electromagnetic fields.
