Tungsten is used as a filament in an electric bulb due to its properties including the highest melting point (3422 °C, 6192 °F), the lowest vapor pressure (at temperatures above 1650 °C, 3000 °F) and the highest tensile strength of all metals in pure form.

Tungesten is used as a filament in electric bulb because of the highest melting point, greatest tensile strength out of all the metals,lowest vapor pressure etc.... . That's why it is used as a filament in electric bulb.
