Because it has a very very high melting temperature: 6191F, 3422C. However it is also
very difficult to work with, so early light bulbs used carbon for making the filament instead.
Around the year 1900, carbon filaments were replaced with tantalum filaments. It was not
until about 1910 that it became practical to make tungsten filaments.

What is filament of light bulb made of?
Filament of bulb is made up of Tungsten.perfect answer:filament of bulb made of tungsten because of its melting point tungsten s m.p. is 3422 c and it produces through a method called extrusion process and due to its high melting point it do not melt due to heat. thnx if any1 have some general knowledge plz send me at wanted_rk2000@yahoo.comTungsten.
What causes a light bulb to turn black when they burn out?
As an incandescent light bulb is used, tungsten slowly evaporates from the filament causing it to get thinner. When it gets too thin it can no longer carry the current and part of it melts causing the bulb to blow out.
What type of wire is used in a light bulb?
A light bulb glows because of a very fine wire inside the glass bulb called a 'filament'. When an electrical current is put through the filament, assuming the voltage is high enough, it will begin to heat up and glow because such a small wire cannot handle the flow of electrons and has to discharge them through heat and light. Also if you put to much voltage in it will heat up the filament too much and melt it. Incandescent (filament) light bulbs fail over time because they slowly lose small amounts of wire until the filament breaks and stops glowing.
What element is found in cheaper light bulbs?
Fluorescent tubes create ultraviolet light when electricity is passed through mercury vapor. The UV light causes the phosphors, dusted over the inside of the tube, to fluoresce--or give off visible light. Three of the elements found in the tube would be: Phosphorous, mercury, and tungsten.
What element is used as the metal in domestic light bulbs?
tungsten <<>> Also along with the above, aluminium for the shell, steel for the filament holders, and in past years brass was used for the shell until manufactures found out it was cheaper to use aluminium for the job.
What is the filament in a light bulb made of?
The filament in a light bulb is typically made of tungsten.
Light bulb filament?
What is Tungsten
What is the filament in the light bulb called?
Tungsten.
What is the filament in an incandescent light bulb made of?
The filament in an incandescent light bulb is typically made of tungsten.
What is the filament inside a light bulb?
The filament inside a light bulb is typically made of tungsten. When electricity passes through the filament, it heats up and produces light through incandescence.
What gives off light in tungsten light bulbs?
Tungsten light bulbs produce light when an electric current heats a tungsten filament to a high temperature, causing it to glow and emit light. The tungsten filament is housed in a bulb filled with an inert gas, such as argon, which helps prevent the filament from evaporating too quickly.
What element is essential in a light bulb?
In the old style filament lightbulbs it was tungsten (wolfram).
How do tungsten-halogen bulbs generate light?
Inside a tungsten-halogen bulb, electrons flow through a tungsten filament. The filament heats up and emits light.
What element is in an incondescent light bulb filament?
The filament in an incandescent light bulb is typically made of tungsten. Tungsten is a metal with a high melting point that allows it to produce light and heat when an electric current passes through it.
What is the material used in the construction of a light bulb filament made of?
The material used in the construction of a light bulb filament is typically tungsten.
What is now days light bulb filament made out of?
tungsten
What is in a light bulb filament?
Usually an element called tungsten.
