  • Copper Coil

    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.
