Why the filament of a bulb is made of tungsten but not of copper?

Because when heated, copper would react with the oxygen in the air and oxidise. Tungsten is not as reactive (I think, but check). I think Argon can also be used as a light bulb filament.
Tungsten has a higher melting point than all other metals (3422 degrees C) and a very low coefficient of expansion, making it suitable for the filament in incandescent light bulbs. Argon is an inert gas used in incandescent bulbs to prevent chemical reactions which might degrade the filament.

What is filament in a bulb?
The filament is the small coil that glows when the bulb is on. I believe its made out of tungsten
What is now days light bulb filament made out of?
tungsten
How tungsten filament made?
Tungsten filament is used in the creation of the light bulb. It can be made in different shapes like coiling, and horizontal or vertical helix.
Is copper wire the same as thugsten wire?
No. Copper wire is made of the element copper. Tungsten wire is made of the element tungsten. Copper wire is made to conduct electricity. Tungsten wire is made for the filament in light bulbs as tungsten does not melt under even very high temperatures.
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 is the metal of a light bulb made of?
The wire inside of an electrical light bulb is called a "filament". The word filament comes from the Latin word "filum" which means "thread". In various fields there are many different types of filaments with different uses, however the ones inside of light bulbs are made out of tungsten and work by super-heating by passing electricity through it.
What is the part of a light bulb that gets hot and produces lights?
In an incandescent light bulb this is the filament. It is usually made of tungsten.
What is a filament resistor?
A filament bulb resistor is the common type of light bulb. It contain a thin coil wire called filament. It produces light as a result. It is made mainly from the element tungsten. The metle tungsten has very high melting point and it is a good conductor of electric current
What is the thin wire inside a bulb called?
It is called a filament and usually made of tungsten steel.
How does the filament in a light bulb work?
it is made of tungsten and is a resistor when current flows thru it it heats up and glows
What is the name of the wire in a light bulb?
Filament. Correct; made of tungsten wire in most incandescent bulbs.
What elements are in lightbulbs?
Tungsten is the element that the light bulb's filament is made from. The element's atomic symbol, W, comes from the word Wolfram, the original name for tungsten.
