Hard Drawn Copper Foil

Hard-drawn copper foil is composed of copper wires with larger diameters and higher tensile strength and is used as a conductor.
Hard-drawn Copper foil is an important metallic material, featuring high strength, conductivity and heat conductivity.
Standard: TB/T3111-2005.

Electronic and electrical applications: Copper foil is often used as the conductive layer of printed circuit boards (PCB). Copper foil can serve as the base material for conductive lines and is used in the manufacturing of electronic devices, communication equipment, computers and other electronic products.

Electromagnetic shielding: Copper foil has excellent electromagnetic shielding properties and can be used to prepare electromagnetic shielding materials to block or reduce electromagnetic wave interference. Copper foil shielding materials are widely used in electronic devices, electromagnetic shielding rooms, communication systems and medical equipment, etc. They provide excellent shielding and protection performance.

Heat conduction materials: The high thermal conductivity of copper foil makes it an excellent heat conduction material. It is often used in heat sinks, heat transfer plates, chip cooling, etc., to effectively conduct and dissipate heat.

Decorative and artistic applications: Due to the metallic luster and malleability of copper foil, it is widely used in the decorative and artistic fields. Copper foil can be used to make decorations, sculptures, painting backgrounds, handicrafts, etc., adding unique appearance and texture to the works.
Packaging materials: The softness and corrosion resistance of copper foil make it an ideal packaging material. It can be used in food packaging, pharmaceutical packaging, electronic component packaging, etc., providing good shielding and protection performance.

The application fields of copper foil are very extensive. Here are some of the main application areas:
Lithium battery field: Lithium battery copper foil is an important material that constitutes the carrier and current collector of the negative electrode material in lithium batteries, featuring excellent ductility, conductivity, and stable chemical properties. Lithium battery copper foil has abundant raw materials, mature processing technology, and low processing costs, making it the preferred choice for the negative electrode material carrier and current collector in lithium batteries.

Electronic circuit field: Electrolytic copper foil is an important material for copper clad laminates (CCL) and printed circuit boards (PCB), as well as for the manufacturing of lithium-ion batteries. In the current rapid development of the information technology industry, electrolytic copper foil is known as the "nerve network" for signal and power transmission and communication in electronic products.

Soft packaging field: Soft packaging is a bag-shaped container made of soft composite packaging materials. The emergence of soft packaging has greatly improved the mechanization and automation levels of the food and beverage industry, and accelerated the modernization and socialization process of people's dietary life.

Automobile field: The market demand for automotive foil is increasing rapidly. Automotive foil comes in two types: one is the composite foil for automotive air conditioners, and the other is the composite foil for automotive radiators, used for manufacturing automotive water tank radiators, automotive condensers, and evaporators.

Electrolytic capacitor field: The copper foil used in electrolytic capacitors is a corrosion material that works under polar conditions. Electrolytic capacitors have good performance, low price, and wide applications, so they have a promising market prospect.
