Product Application
Ed shielding copper foil with high elongation and high tensile strength, can be used in many fields. We can offer specific lithium-ion battery, double matte and double shiny ED copper. We can also provide 2OZ to 6oz (nominal thickness 70um to 210um) shielded ED copper foil for electrical product shielding, in particular, transformers, cables, mobile phones, computers, mechanical processing, aerospace, and so on. More importantly, HTE (high temperature elongation) copper foil from 1/2 oz to 2 oz and VLP-HTE-HF (extremely low thickness, high temperature elongation, heavy ED copper foil, for PCB, with a maximum size of 1295 mm x 2450 mm.
