Question

Why metalware ductile but non_metals are not????

Answer 1

The ductility is the property of being able to be drawn into wires. Most metals are ductile because they can be drawn into wires, but as most non-metals are brittle, they are not ductile and cannot be drawn into wires.

There are, of course, some exceptions and some metals may be non-ductile and some non-metals may be ductile.
