Properties of electrolytic copper foil and calendered copper foil

2021-01-25 02:35:05

Conductivity: the conductivity of rolled copper is weaker than that of electrolytic copper. Ductility: The compressibility of rolled copper material is better than that of electrolytic copper material. The elongation of rolled copper material reaches 20-45%, while that of electrolytic copper material is only 4-40%. Flexibility: the measurement of bending
