Description
Copper–Carbon Nanotube Fibers Composite Wires (Cu–CNT)
Diameter: 10–30 µm | Coating Thickness: 1 µm | Electrical Conductivity: 1×10⁷ S/m
Copper–Carbon Nanotube (Cu–CNT) composite wires represent a transformative class of materials that combine the electrical and thermal advantages of copper with the mechanical strength, flexibility, and nanoscale characteristics of carbon nanotubes. These fibers are engineered to meet the ever-growing demand for lightweight, high-performance conductive materials across various industries.
Unlike pure copper, Cu–CNT composite wires offer improved conductivity-to-weight ratios, exceptional current-carrying capacity, and superior resistance to electromigration and thermal degradation—making them ideal for next-generation electronic devices, aerospace systems, and automotive technologies.
