Abstract
A method of making a conductor includes folding/stacking/rolling an ultra-conducting copper foil into a multiple layer folded/stacked/rolled ultra-conducting copper foil. Cladding the multiple layer folded/stacked/rolled ultra-conducting coper foil with one of copper and aluminum into a cladded folded/stacked/rolled ultra-conducting copper foil and plastically deforming the cladded folded/stacked/rolled ultra-conducting copper foil into one of a cladded ultra-conducting copper wire, bar, and cable.

A method of making a conductor, comprising:
- folding an ultra-conducting copper foil into a multiple layer folded ultra-conducting copper foil;
- cladding the multiple layer folded ultra-conducting copper foil with one of copper and aluminum into a cladded folded ultra-conducting copper foil having a rectangular cross section;
- and
- plastically deforming the cladded folded ultra-conducting copper foil into a cladded ultra-conducting copper wire having a rectangular cross-section.
A method of making a conductor, comprising:
- stacking an ultra-conducting copper foil into a multiple layer stacked ultra-conducting copper foil;
- cladding the stacked ultra-conducting copper foil with one of copper and aluminum into a cladded stacked ultra-conducting copper foil having a rectangular cross section;
- and
- plastically deforming the cladded stacked ultra-conducting copper foil into a cladded ultra-conducting copper wire having a rectangular cross section.
A method of making a conductor, comprising:
- rolling an ultra-conducting copper foil into a multiple layer rolled ultra-conducting copper foil;
- cladding the rolled ultra-conducting copper foil with aluminum into a cladded rolled ultra-conducting copper foil;
- and
- plastically deforming the cladded rolled ultra-conducting copper foil into a cladded ultra-conducting copper wire having a rectangular cross section, wherein rolling the ultra-conducting copper foil includes stacking copper foil with the ultra-conducting copper foil and rolling the stack of ultra-conducting copper foil with copper foil to form the multiple layer rolled ultra-conducting copper foil.
