What is a significant feature of copper as an electrical conductor in aviation?

Copper's high conductivity is one of the most significant features that make it an excellent electrical conductor in aviation. This property allows copper to efficiently carry electrical current with minimal resistance, which is crucial for the performance and reliability of electrical systems in aircraft. High conductivity means that less energy is lost as heat during the transmission of electricity, enabling systems to function optimally and reducing the overall weight and size of wiring needed. This is particularly important in aviation, where every ounce counts for fuel efficiency and performance.

While copper is relatively inexpensive compared to some other materials, and it provides good corrosion resistance (although it can oxidize), its standout feature remains its ability to conduct electricity at a high level efficiently. This characteristic makes copper the preferred choice for wiring and electrical systems in aviation applications. Additionally, although copper is denser than some materials, its conductivity benefits outweigh concerns about weight in most aviation applications.
