Claims
- 1. A process for making copper wire comprising:

- 10. The process of claim 1 wherein said foil has an elongation at 180.degree. C. in the range of about 24% to about 38% after being annealed at 177.degree. C. for 15 minutes.
- 11. The process of claim 2 wherein said foil has an ultimate tensile strength at 23.degree. C. in the range of about 36,000 to about 48,000 psi.
- 12. The process of claim 2 wherein said foil has an elongation at 23.degree. C. in the range of about 23% to about 36%.
- 13. The process of claim 2 wherein said foil has an ultimate tensile strength at 180.degree. C. in the range of about 22,000 to about 32,000 psi.
- 14. The process of claim 2 wherein said foil has an elongation at 180.degree. C. in the range of about 25% to about 40%.
- 15. The process of claim 1 wherein the average grain size for said foil is up to about 3 microns.
- 16. The process of claim 1 wherein the average grain size for said foil after being annealed at 177.degree. C. for 15 minutes is up to about 5 microns.
- 17. The process of claim 2 wherein the average grain size for said foil is up to about 8 microns.
- 18. The process of claim 1 wherein said wire has a round cross-sectional shape.
- 19. The process of claim 1 wherein said wire has a square or rectangular cross-sectional shape.
- 20. The process of claim 1 wherein said wire has a cross-sectional shape in the form of a cross, star, semi-circle, polygon, race track, oval, flat or ribbed-flat.
- 21. The process of claim 1 wherein said wire has a cross-sectional shape in a form substantially as illustrated in any one of FIGS. 3-20.
