Aluminium is essential in the electrical and electronics sector due to its excellent conductivity, light weight, and cost-effectiveness. It is widely used in power cables and overhead transmission lines, replacing copper for energy efficiency. Aluminium heat sinks are crucial in cooling electronic devices like computers, LEDs, and inverters.

It is also used in electrical enclosures, switchboards, and control panels for its durability and non-magnetic properties. Printed circuit boards (PCBs) often feature aluminium bases for heat dissipation. Its high thermal conductivity makes aluminium ideal for lighting systems and transformer components.
