Copper Foil Description
Copper is a ductile metal with very high thermal and electrical conductivity. Pure copper is rather soft and malleable and a freshly exposed surface has a pinkish or peach color. It is often used as a thermal conductor, and electrical conductor, building material, and composition of various alloys.
Our copper coil rolls are ideal for electrical conductivity uses. This product is carried in Alloy 110 and 102, with other alloys available upon request. Tempers are available in annealed, full hard, and as rolled. The copper foil rolls we offer are ideal for use in the following applications: cable wrap, batteries, solar/alternative energy, circuit boards, and transformers.

Copper Foil Applications
- Printed Circuit Boards (PCBs): Copper foil is extensively used as the conductive layer in PCBs for all types of electronic devices.
- Electromagnetic Shielding: Due to its ability to block and absorb electromagnetic and radio frequency interference (EMI/RFI), copper foil is used in shielding applications to protect electronic devices, cables, and enclosures.
- Batteries: Copper foil serves as a current collector in lithium-ion batteries, particularly in the anode construction.
- Heat Exchangers and Heat Sinks: The excellent thermal conductivity of copper makes its foil ideal for use in heat exchangers and heat sinks.
