I'm not sure why you think it cannot be used as a fuse. Granted, it's not the best idea, it is possible.
.002" Tungsten wire will glow and burn when it undergoes a current of approximately 9A. At 10A, this gauge tungsten wire will emit a bright white light, and fuse. There are, however many reasons why you shouldn't use it as a fuse.
One reason it shouldn't be used as a fuse that is burns extremely bright (damaging to retina), and when exposed to oxygen, it creates toxic fumes. Tungsten also has a high melting point, so when it fuses, and sparks that are emitted pose a fire hazard.
Incandescent light bulbs use usually use tungsten wire, but are filled with a noncombustible gas (e.g., argon) which keeps the tungsten from oxidizing and 'burning up'.
What else can I help you with?
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.
Why tungsten wire is not used in an electric heater?
Tungsten wire is not commonly used in electric heaters due to its high melting point and cost. While tungsten can withstand high temperatures, it is more expensive than other materials like nichrome that are commonly used for heating elements. Nichrome is a more cost-effective option that provides similar heat-resistant properties for electric heaters.
What is the thin wire is an electric bulb that glows called?
The thin wire in an electric bulb that glows is called a filament. It is typically made of tungsten and glows when electricity passes through it, producing light.
What is the thin wire inside a bulb called?
It is called a filament and usually made of tungsten steel.
Why copper can't be used as fuse wire?
Copper is a metal having high melting point and very low specific resistance. in case of excess current flowing in the circuit it will not be able to melt wire quickly and break the circuit protecting it.
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 tungsten wire what is it made up of?
Tungsten wire is a very thin wire that is made up of the element tungsten. It is known for its high melting point, strength, and resistance to corrosion, making it ideal for use in various electrical and heating applications. Tungsten wire is commonly used in light bulbs, electronic devices, and heating elements.
Why cant an electric fuse be replaced by electric wire?
Because then it wouldn't 'blow' at the prescribed amperage. -A fuse is made with very fine tolerance wire to melt at an EXACT amperage.
Why tungsten metal wire is not used in heater?
A heater does not get hot enough to benefit from the expense of using tungsten wire. Most heaters use either wire made of an alloy called nichrome or plated ceramic heating elements. Heaters generally operate at red or orange heat (i.e. 1409F to 1908F) and can use nichrome wire. Lightbulbs operate at white heat (i.e. greater than 2309F) and use tungsten wire, but tungsten is hard and expensive to make into wire compared to softer metals.
What is the strongest thin wire available on the market?
The strongest thin wire available on the market is typically made of tungsten or tungsten alloys.
Why can't copper wire used as a fuse wire?
Metal with a lower melting point is preferred for fuse wire to reduce the risk of fire.
Why tungsten wire used in domestic wiring and why?
Tungsten wire is not commonly used in domestic wiring. It is more commonly used in applications such as incandescent light bulbs, electronic components, and heating elements due to its high melting point and resistance to corrosion. Instead, copper wire is typically used in domestic wiring due to its excellent conductivity and cost-effectiveness.
Why is Tungsten used in lightbulbs?
Tungsten is used in bulbs as filament, because it is the only wire that can be bent easily to produce friction. In the 5mm coil of the wire there are almost 15 rounds of coiling and when the electrons flow through it, it glows and emits heat as well due to friction.
Why tungsten wire is not used in an electric heater?
Tungsten wire is not commonly used in electric heaters due to its high melting point and cost. While tungsten can withstand high temperatures, it is more expensive than other materials like nichrome that are commonly used for heating elements. Nichrome is a more cost-effective option that provides similar heat-resistant properties for electric heaters.
Why can not copper wire be used as a fuse wire?
The fuse needs a low melting point and reletivelyhigh resistance so that it melts at the proper current
What type of wire is used in fuse and why?
Fuse wire is usually made with metal that has a low melting point, e.g. tin, to lessen the risk of fire.
Which metal used in fuse wires?
Apparently mainly tinned copper is used in fuse wires. I have heard that there are a lot of other metals used as teh fuse wire though!
