Answered by ansshama

Pure tungsten has some amazing properties including the highest melting point (3695 K), lowest vapor pressure, and greatest tensile strength out of all the metals.Because of these properties it is the most commonly used material for light bulb filaments.

syedaaiman3301: Filament is used in bulb because it has very high melting point . As to light a bulb we need high voltage current which can melt any other metal very easily so we use tungsten in bulb.
