What is the most common material used in cables?

The most common material used in cables is copper due to its excellent electrical conductivity and flexibility. Copper is highly efficient in transmitting electrical signals and power, making it the preferred choice for electrical wiring in residential, commercial, and industrial applications. Its ability to minimize resistive losses in electrical systems contributes to its widespread use, particularly in applications where high efficiency is essential.

Additionally, copper's durability and resistance to corrosion enhance its performance and longevity, further supporting its prevalence in cable manufacturing. While aluminum is also used in some applications due to its lower cost and lighter weight, it does not match copper's conductivity, which is why copper remains the dominant choice for most high-performance cables.
