Copper tape https://ukrstarline.ua/ru/cvetnoj-prokat-i-splavy/med/mednaya-lenta is a rolled product with a rectangular cross-section and a flat surface. The source material is a derivative of high-purity primary copper (99.99%), i.e. with a hundredth of an impurity in the composition. It is produced by cold rolling or pressing. Both methods involve deformation of the hot-rolled blank to a flat state.
