however, that symmetrical structure is 🔜 deformed 🔙 during manufacture, especially when the copper wire is pulled through the final die, although most likely deformation has already occurred during pulling through previous dies. Thus, the crystal lattice structure is no longer symmetrical, far from it.
Yes, but what if the direction the cable is pulled through the dies is reversed for each pass? Thus, the directionality imparted via the first pass through the die is neutralized via the second (reverse direction) pass. How do we know this isn't SOP?
