Purple copper foil with high flexibility and ductility

The metal material with the highest copper content is called pure copper. Because its surface color is reddish purple, also known as purple copper. Copper has high flexibility and extensibility. Meanwhile, the conductivity and thermal conductivity of copper are also excellent. The purple copper foil produced by Advanced Institute Technology not only has the characteristics of high purity and low impurities, but also has a high surface smoothness, flat plate shape, and excellent uniformity. Suitable for use in electrical and thermal conductionelectromagnetic shielding materialThe rolled purple copper foil produced by Advanced Institute Technology also has good processability and is easy to form and laminate. Due to the spherical structure of rolled copper foil, annealing process can be used to control its soft and hard states, making it more suitable for diverse terminal applications. Advanced Institute Technology can also produce products of different thicknesses and widths according to customer needs, thereby reducing production costs and improving processing efficiency.
