Step-by-step explanation:
Metals have various properties and are widely used in various application purposes. Metals have good conductivity and ductility property for which they are used in electrical wires like copper. They have good luster because of which they are used in mirrors.
Similarly, tungsten is used in the filament of the bulb because of the properties like electrical conductivity, ductility and high melting point. Thus the filament does not melt even if the heat production is high.
