What can be used instead of tungsten?

Other metals (osmium, tantalum, molybdenum) have been used as well, but tungsten seems to outperform them, at least once production cost is considered as well.

What material is used for bulb filament?

Tungsten
Tungsten is used for making filament of an electric bulb due to the following reasons: Being an alloy it has a very high melting point. It has very high resistivity so it does not burn easily at room temperature. The lamp glows at high temperatures.

Does copper make a good lightbulb filament?

Copper is a good conductor. You need some resistance to make it heat up and glow to be useful as a light source.

Can Nichrome be used in bulb?

Nichrome is not used as filament in incandescent lamps.

Is used as a filament in bulb?

The filament used in the bulb is tungsten.

What is the metal filament in a light bulb?

tungsten
Incandescent light bulbs have filaments which are made mainly from the element tungsten, the metal element used for the filaments in incandescent light bulbs.

Why is tungsten used as filament?

The metal tungsten is almost exclusively used for the filament of the electric lamp because it has a very high melting point due to which it does not melt even when it is heated to high temperatures due to the passage of electric current.

Why is tungsten used instead of copper?

When the contact is very fine grained (VFG), the electrical conductivity is much higher than a normal piece of copper tungsten. Copper tungsten is a good choice for a vacuum contact due to its low cost, resistance to arc erosion, good conductivity, and resistance to mechanical wear and contact welding.

How do you make a filament bulb?

To make a filament, cut a two-inch piece of iron wire (the filament) from the roll and attach it to the two copper wires hanging down from the lid by twisting the iron wire around each end of the copper wire. The iron wire stretches across the space between the two copper wires. Now you have a filament.

Can we replace tungsten filament of bulb with Nichrome?

At higher temperatures the wavelengths emitted are shorter. In order to emit light that we can see, i.e. 750nm to 400nm,the filament of the bulb needs to be at a temperature of about 3000degrees celsius, which is incredibly hot. Nichrome would melt at this temperature, but Tungsten is just fine!

Can we replace tungsten filament with Nichrome?

Physical Science Nichrome also has high resistivity but its melting point is lower then the tungsten so its thin wire (used as filament) will be melted with continuos high heating.

Can iron be used as filament?
