Why are copper and aluminum the most common metals for electricity transmission, and why not other metals like iron?

2025-08-08
Copper and aluminum are favored for their excellent electrical conductivity, low resistance, and high ductility, which allows them to be drawn into wires. While other metals like silver are even better conductors, they are far too expensive for large-scale use. Iron, on the other hand, is a much poorer conductor, heavier, and prone to rust, which makes it unsuitable for power transmission. Our company provides a wide range of OHTL equipment and underground cables specifically designed to handle both aluminum and copper conductors, ensuring efficient and reliable power delivery.
