COPPER FOILS

Copper foil is a thin sheet of copper with a thickness typically less than 0.2 mm. It is flexible and can be easily manipulated

Our Copper Foils are known for their high quality, perfect shape, smooth surface, and excellent mechanical properties. We carefully monitor various factors to ensure that these foils meet the highest standards, making them ideal for many uses.

What is Copper Foil?

Copper foil is a thin sheet of copper, usually rolled or electro-deposited, that can range from micrometers to millimeters in thickness. Because copper is highly conductive and flexible, copper foil is widely used in electronics, energy storage, and industrial applications.

Key Properties of Copper Foil

  • Excellent Electrical Conductivity – Ideal for printed circuit boards and batteries.
  • High Thermal Conductivity – Transfers heat efficiently, useful in heat dissipation.
  • Flexibility – Thin and easy to bend or shape without breaking.
  • Corrosion Resistance – Withstands environmental exposure and oxidation.
  • Adhesive-Friendly – Can bond easily with resins, adhesives, and other materials.

Types of Copper Foil

  • Rolled Copper Foil (RA Foil) – Made by rolling copper into thin sheets; flexible and durable.
  • Electrolytic Copper Foil (ED Foil) – Produced through electro-deposition; widely used in PCBs.
  • Surface-Treated Copper Foil – Enhanced bonding with adhesives and resins.
