Product Overview

What are Copper Foils?

Copper Foils are thin strips or sheets of copper manufactured by precision rolling to achieve uniform thickness and superior surface finish. Their combination of excellent electrical conductivity, flexibility, and mechanical strength makes them an ideal conductor for applications where compact design and efficient current flow are essential.

Compared with conventional conductors, copper foils offer greater flexibility and a larger surface area, enabling efficient heat dissipation and improved current distribution. They are widely used in transformer windings, laminated flexible connectors, switchgear, PCB manufacturing, electromagnetic shielding, battery systems, and renewable energy equipment. Copper foils are also used in busbar laminations and specialised electrical assemblies where space-saving and flexibility are important.
