Which element is used in the filaments in incandescent lamps?
Tungsten.More informationExperiments were made with different materials to use as the filament, including natural fibres, pure metals and alloys of different metals, to find the material which had the longest life whilst glowing brightly enough to give out visible light. The metal Tungsten was found to be the best, because of its high melting point (almost 3700 K) and good resistance to electrical current.
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.
Is Tungsten a raw material?
No, it is a metal that has to be smelted out of a mineral called wolframite. It is this wolframite that is the initial raw material.
Is tungsten a metal or a non metal?
Tungsten is a Transition metal. Thus for making it a metal.
What is the filament inside the bulb made up of?
Incandescent light bulbs have filaments which are made mainly from the element tungsten and/or alloys which include tungsten.Tungsten is the metal element used for the filaments in incandescent light bulbs.Experiments were made with different materials to use as the filament, including natural fibres, pure metals and alloys of different metals, to find the material which had the longest life whilst glowing brightly enough to give out visible light. The metal Tungsten was found to be the best, because of its high melting point (almost 3700 K) and good resistance to electrical current.For more information see the answer to the Related Question shown below.Carbonized cotton was originally tried, and had moderate success. However, the material that finally worked the best was a filament made of tungsten, which shone brighter and lasted much longer.It is made up of Tungsten which have an melting point of 3380 degree Celsius.
What two properties of the metal tungsten makes it good material for the filament?
Magnesium and Titanium.
What are two properties of the metal tungsten that make it good material for the filament?
Magnesium and Titanium.
Which metal is used in making filament of a bulb?
The metal is Tungsten.
Why do lightbulbs burn out?
They burn out from 1) the rapid heating and cooling of the Tungsten filament, and 2) from the tungsten atoms being released from the metal filament by way of the extremely high temperatures. Eventually the tungsten metal fails and the filament breaks.
What is a metal that glows when electricity is passed through it?
It is a tungsten filament.
What is metal with which the filament is made?
Assuming you're talking about light bulbs... the filament is made from Tungsten.
What is the metal in domestic light bulbs?
Tungsten in the filament of incandescent lightbulb.
What is a light bulb filament?
the filament is the metal peice in a bulb that glows.Tungsten is most often used in a lightbulb.
Why scientists use tungsten metal in manufacturing the filament of the light bulbs?
it glows and emits light.
The metal with the highest melting point for this reason it is often used as the filament in light bulbs?
tungsten

Why are filament wires made up of Tungsten?
Tungsten, or wolfram, has the highest melting point of any non-alloy metal and the second highest of all the elements after carbon. When a current passes through a filament that is made from tungsten, the metal heats up to a point that it emits light. The tungsten reaches a very high temperature, noticable because of the bright light it then emits, but it does not melt.
