Copper strip is a kind of metal component, the product specification is 0.1-3 & times; 50 ~ 250mm copper strip products in various states. Copper rolled products with a thickness of 0.06-1.5mm are called copper strip. At present, the maximum thickness of the strip is 2mm and the maximum width is 600mm. The length of the strip is generally only the minimum length according to the standard, and it is supplied in coils. The professional uses of the copper strip are different due to the different materials of the copper strip. The professional uses of the common grades of copper strip are as follows.
