CM1334 Copper Foil (Cu Foil)

Copper Foil Description

Copper is a highly ductile metal known for its excellent thermal and electrical conductivity. Pure copper is soft and malleable, exhibiting a characteristic pinkish or peach color when freshly exposed. It is widely used as a thermal and electrical conductor, in building materials, and as a component in various alloys.

Stanford Optics offers copper coil rolls primarily in Alloy 110 and 102, with additional alloys available upon request. These are available in different tempers including annealed, full hard, and as rolled. The copper foil rolls are well-suited for applications such as cable wrapping, batteries, solar and alternative energy systems, circuit boards, and transformers.

Copper Foil Applications

• Printed Circuit Boards (PCBs): Copper foil serves as the conductive layer in PCBs for a broad range of electronic devices.
• Electromagnetic Shielding: Its ability to block and absorb electromagnetic and radio frequency interference (EMI/RFI) makes it ideal for shielding electronic devices, cables, and enclosures.
• Batteries: Copper foil is used as a current collector in lithium-ion batteries, particularly in the anode.
• Heat Exchangers and Heat Sinks: Thanks to copper's superior thermal conductivity, its foil is used in heat exchangers and heat sinks to efficiently dissipate heat.

Copper Foil Safety Information

Copper Foil Packaging

Cooper foils are always clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage or transportation.
