    摘要: This invention relates to copper wire having a substantially uniform unoriented grain structure that is essentially columnar grain free. This invention also relates to a process for making copper wire comprising: cutting copper foil to form at least one strand of copper wire, said copper foil being an annealable electrodeposited copper foil having a substantially uniform unoriented grain structure that is essentially columnar grain free, said foil being characterized by a fatigue ductility of at least about 25% after being annealed at 177.degree. C. for 15 minutes; and shaping said strand of wire to provide said strand with desired cross-sectional shape and size. This invention also relates to a process for making copper wire comprising: flowing an aqueous electrolyte solution between an anode and a cathode and applying an effective amount of voltage across the anode and the cathode to deposit copper foil on the cathode, said electrolyte solution being characterized by a chloride ion concentration of up to about 5 ppm and an organic additive concentration of up to about 0.2 ppm; cutting said foil to form at least one strand of wire; and shaping said strand of wire to provide said strand with desired cross-sectional shape and size.
