What are copper wires commonly made of?

Copper wires are primarily designed for efficient electrical conductivity and typically consist of multiple strands of copper. This construction helps enhance flexibility and durability, allowing the wires to withstand bending and twisting while maintaining performance. The use of multiple pairs of copper wires allows for improved signal transmission and reduces the potential for interference, making them ideal for various applications, such as networking and telecommunications.

Additionally, the configuration using multiple strands ensures that the wire can carry more current without overheating, which is crucial for maintaining safety and efficiency in electrical systems. Other options like aluminum strands and fiber strands do not pertain to typical copper wire composition, as aluminum is a different type of metal with its own properties, and fiber strands refer to optical fibers used for data transmission rather than electrical conductivity. A single copper wire, while it does exist, lacks the advantages that multiple strands provide in terms of flexibility and capability.
