What is the primary advantage of using copper over aluminum in electrical conductors?

Choosing copper over aluminum in electrical conductors primarily revolves around its superior conductivity. Copper has a higher electrical conductivity than aluminum, meaning that it can carry more current for a given size and length of wire. This characteristic is crucial in electrical applications where efficiency and performance are paramount.

Higher conductivity results in reduced energy losses due to resistance, making copper conductors more efficient in transmitting electrical power. They also allow for a smaller conductor size compared to aluminum for the same level of current carrying capacity, which can be beneficial in applications where space is limited or weight considerations are critical.

While aluminum is often lighter and can be less expensive, these factors do not outweigh the significant advantage of copper's conductivity when it comes to performance in electrical systems. Thus, using copper ensures better efficiency and reliability in electrical installations.
