1. A process for making metal wire, comprising:
- (A) forming a thin web of metal foil having a thickness of about 0.001 to about 0.05 inch, said metal being selected from the group consisting of copper, gold, silver, tin, chromium, zinc, nickel, platinum, palladium, iron, aluminum, steel, lead, brass, or an alloy of one or more of the foregoing metals;
(B) cutting said foil to form at least one strand of wire; and
(C) shaping said strand of wire to provide said strand with desired cross-sectional shape and size.

Abstract
This invention relates to a process for making metal wire, comprising: (A) forming metal foil; (B) cutting said foil to form at least one strand of metal wire; and (C) shaping said strand of wire to provide said strand with desired cross-sectional shape and size. This process is particularly suitable for making copper wire, especially copper wire having a very thin diameter (e.g., about 0.0002 to about 0.02 inch).

25. A process for making copper wire comprising:
-
(A) flowing an electrolyte solution between an anode and a cathode in an electroforming cell and applying an effective amount of voltage across said anode and said cathode to deposit copper on said cathode, said electrolyte solution being characterized by a free chloride ion concentration of up to about 5 ppm; (B) score-cutting said copper to form a strand of copper wire and removing said strand of copper from said cathode; and (C) shaping said strand of copper wire to provide copper wire with desired cross-sectional shape and size.

27. A process for making metal wire, comprising:
- .
(A) forming metal foil; (B) cutting said foil to form at least one strand of wire; and (C) shaping said strand of wire to provide said strand with desired cross-sectional shape and size; wherein said metal foil is electrodeposited copper foil and is formed in an electroforming cell on a cathode during step (A), and said cutting step (B) comprises score cutting said foil while on said cathode to form said strand of wire and removing said strand from said cathode. - View Dependent Claims (28)
