Speaker cable arrows???

Uhmmmm, most copper wires for flexible cable is annealed, which does cause recrystalization and improves conductivity, but importantly also makes it softer and more workable (and less likely to break). Some copper wire is intentionally not annealed to make it more difficult to hold a bend and increase tensile strength.  Really, this is not a debatable item. It is done day in and day out and is well understood.

Annealing where recrystalization occurs makes copper wire more ductile. No hammers required.

>>>>Look 👀 You don’t have to be a genius to figure out that stretching metal or hammering it further deforms what is originally a symmetrical crystal structure. You do know metals are crystals, right? In the case the solid wire conductor being pulled through a die the deformation is primarily in 2 dimensions. Hence the directionality. 🔛 Follow?
