Which metal has a melting point of over 3000 degrees celsius is used to make light bulb filaments?
The filament wire of an incandescent light bulb is a tightly-coiled wire made from Tungsten. Before it is coiled up it is long and thin.The element is always supported on two stronger wires made of another kind of metal which can withstand the intense heat inside the bulb.Another answerThere are many different kinds of light bulbs that use other metals! Just to name a few: Mercury(Hg), Tungsten(W), Sodium(Na).Tungestun

What brand of power supply last the longest?
GE is known for its reliable and long lasting power supplies.
Why did the crusades last so long?
You had to gather your army, supply it and then travel (by land or ship) to the Holy Land.
What are light bulb filaments?
Usually Tungsten. Carbon filaments were used first, but scientists found that tungsten works for a far longer time period. Unfortunately, most filaments designed today don't last near as long as the bulb is rated at. Just put a dated replacement sticker on a light bulb and see when the next time you replaced it how long it went. You will be surprised.
In gas tungsten-arc welding a long electrode extension is highly desirable true or false?
False, this will cause contamination of the tungsten electrode as there will be insufficient gas coverage.
If the nitrogen and oxygen were not replaced in the atmosphere how long would your present supply of gases would last?
If you are the only one living on earth it would last for your lifetime.
How long does a incandescent light bulb last?
It depends on the quality of filament, how often it is switched on and off and fluctuations of supply voltage.
