Copper Coil
Copper coil is a strip or foil-shaped material continuously wound from copper or copper alloys (such as pure copper, brass, bronze, etc.) through hot rolling or cold rolling processes. It is cylindrically wound, with a wide range of thicknesses (from a few micrometers to several millimeters) and widths up to several meters, facilitating transportation and automated continuous production. It is widely used in electronics and information technology (PCBs, flexible circuits), new energy (power batteries, photovoltaics), power transmission, and building decoration.
Description
Copper coil is a strip or foil-shaped material continuously wound from copper or copper alloys (such as pure copper, brass, bronze, etc.) through hot rolling or cold rolling processes. It is cylindrically wound, with a wide range of thicknesses (from a few micrometers to several millimeters) and widths up to several meters, facilitating transportation and automated continuous production. It is widely used in electronics and information technology (PCBs, flexible circuits), new energy (power batteries, photovoltaics), power transmission, and building decoration.
Copper Coil Classification:
By Processing Method:
1. Hot-rolled copper coil: Thicker (typically >3mm), used for building pipes, foundation busbars, etc.
2. Cold-rolled/rolled copper coil: High precision, thin (0.01mm-4mm), smooth surface, used for electronic circuits, transformer windings, etc.
3. Electrolytic copper coil: Extremely high purity (over 99.99%), mainly used in the manufacture of copper-clad laminates (CCL) and lithium battery current collectors.
According to alloy composition:
1. Pure copper coil: Contains ≥99.3% copper, such as T1, T2, C1100, etc. Excellent electrical and thermal conductivity, commonly used in power transmission and electronic shielding.
2. Brass coil: Copper-zinc alloy, such as H62, H65, C2680, etc. High strength, easy to process, mostly used in precision stamping parts and connectors.
3. Bronze coil: Copper-based alloys other than zinc-nickel, such as tin bronze (C5191) and aluminum bronze. Wear-resistant and corrosion-resistant, suitable for springs and bearing components.
4. Cupronickel coil: Copper-nickel alloy, such as B10, B30. Resistant to seawater corrosion, mainly used in marine fittings and precision instruments.
Applications of Copper Coil:
1. Electronics and Electrical Industry: Copper Coil is used to manufacture copper foil for printed circuit boards (PCBs), integrated circuit lead frames, high-frequency connectors, relay contacts, and transformer windings, utilizing its high conductivity to ensure signal transmission efficiency.
2. Power Transmission Equipment: Copper Coil, as a basic material for cable conductors, busbars (copper busbars), and switch connectors, is widely used in power transmission and distribution networks, balancing energy saving and safety.
3. Machinery Manufacturing and Components: Copper Coil is processed into spring sheets, cartridge cases, bearing bushes, valve fittings, and gears through stamping and deep drawing processes, utilizing the high strength and wear resistance of copper alloys (such as brass and bronze coils).
4. Heat Exchange Systems: Copper Coil is used in radiators, condenser tubes, and heat exchangers of air conditioning and refrigeration equipment, leveraging its excellent thermal conductivity to improve energy efficiency.
5. Construction and Decoration: Copper Coil is used to manufacture roofing materials, piping systems, and high-end architectural decorative components, utilizing its resistance to atmospheric corrosion and aesthetic appeal.
6. New Energy and Transportation: Copper Coil is used in electric vehicles for battery connectors and motor stators and rotors; and in rail transit for pantograph contact plates and signaling system cables.
7. Marine and Chemical Industries: Cupronickel or tin bronze coils are used in seawater desalination pipelines, ship propellers, and corrosion-resistant containers to resist seawater erosion and inhibit marine organism attachment.
The specific applications of copper coils depend on their material (e.g., copper, brass, bronze, etc.) and state (soft or hard). Different grades correspond to different strength and conductivity requirements.
