High-precision rolled copper foil is a high-quality material produced by CIVEN METAL. Compared to ordinary copper foil products, it has higher purity, better surface finish, better flatness, more precise tolerances and more perfect processing properties. The high precision copper foil has been also degrease and anti-oxidized, which allows the foil to have longer shelf life and be easier to laminate with other materials. As the material is manufactured and packaged in dust free room, the cleanliness of the product is very high and it meets the requirements of a high-end electronics production environment. All of our high precision rolled copper foil products are controlled and monitored according to the strictest international production standards, with the aim of achieving none defect. It can not just be the substitute of the same grade products from Japan and Western Countries, but also shorter the manufacturing period for our customers.C11000 Copper, Cu > 99.99%Thickness range: T 0.009 ~ 0.1 mm (0.0003~0.004 inch) Width range: W 150 ~ 650.0 mm (5.9 inch~25.6 inch)High flexible properties, uniform and flat surface of copper foil, high elongation, good fatigue resistance, strong oxidation resistance and good mechanical properties.High precision radiator foil is main material in manufacturing automobile, farmer machine, mining machinery, engineering machinery, diesel locomotive, shipbuilding, generator set.Suitable for high-end electronic components, circuit boards, batteries, shielding materials, heat dissipation materials and conductive materials.
