Dear Student,
The term "ductile" means that a metal substance is capable of being stretched into a thin wire without becoming weaker or more brittle in the process.Ductility is a measure of a metal's ability to withstand tensile stress any force that pulls the two ends of an object away from each other.
Metals with high ductility such as copper can be drawn into long, thin wires without breaking. Copper historically has served as an excellent conductor of electricity, but it can conduct just about anything. Metals with low ductilities, such as bismuth,will rupture(break or tear apart) when they're put under tensile stress.Ductile metals can be used in more than just conductive wiring. Gold, platinum and silver often are drawn into long strands for use in jewellery.Gold and platinum are generally considered to be among the most ductile metals.
Regards.
