It is because the stone and wood is too strong for wire to be pulled out.
Aluminum and Copper Wire
You could try, but nonmetals are very brittle, so the wire would probably break.
a ductile material is one that can be pulled out ,or drawn,into a long wire.
Ductility refers to the ability of a metal to be drawn into a wire.
wires cannot be drawn from wood because they are brittle
It is because the stone and wood is too strong for wire to be pulled out.
Wires may only be drawn from ductile (malleable) materials. By the definition of wire, it must be of metal, though some solder wires contain a core of rosin.
The ability to be drawn into a thin wire is a property known as ductility. Iron has ductility.
Metals can be pulled or drawn into a wire, so gold is an example.
The insulation on a wire is applied after the wire is drawn to size.
A substance that can be drawn into wire is indeed called ductile
