Electrolytic copper foil is made of copper raw materials into copper sulfate solution, and then the copper sulfate solution is electrodeposited by electrolytic equipment under the action of direct current. Calendered copper foil is a product made by repeatedly rolling and annealing high-precision copper strip (usually less than 150 micron in thickness) according to the principle of plastic processing.
Application of copper foil production process
Electrolytic copper is widely used in electric, light industry, machinery manufacturing, construction industry, national defense industry and other fields, second only to aluminum in the consumption of non-ferrous metal materials in China. Compared with electrolytic copper foil, calendered copper foil has the characteristics of high strength, good flexibility, good ductility, electroplating, good conductivity and excellent surface gloss. Widely used in electronic appliances, communications, integrated circuits, automobiles, machinery manufacturing, construction and many other industries, it is an irreplaceable raw material or substrate for some products.
