Why is tungsten metal selected for making filaments of incandescent lamps?
(N/A) Tungsten is selected for making the filaments of incandescent lamps because it has a very high melting point (approximately $3380 \, ^\circ C$).
This high melting point allows the filament to become white-hot and emit light without melting away when a large amount of electric current passes through it.
