Too expensive. Ni-chrome wire is cheaper.
Nickel chromium wire with fiberglass insulation is used in very high temperatures.
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.
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'.
"Heating" wire is used in the toaster, electric baseboard heater, blow-drier, percolator, electric space heater, and in just about any other place where electricity is used to produce heat. It's simply a wire with more resistance than 'hook-up wire'. The purpose of the wiring in typical electrical and electronic devices is simply to connect the components to each other. It's made to have as little resistance as possible, so as not to dissipate any electrical energy. But dissipation of electrical energy is the whole purpose of an appliance used to generate heat. The heating element ... comprised of heating wire ... is the main component in that circuit. The heating wire has some resistance ... enough to avoid a "short circuit" that would trip the circuit breaker and possibly melt the house wiring, but little enough so that it draws a large current and gets glowing-red hot when connected across the mains supply. Typically, a fan blows air across the heating wire, to pick up the heat and distribute it into the room or the wet hair.
Copper is used to make electrical wire because it is ductile and is very conductive. The ease with which copper can be worked and drawn ("pulled" or "stretched") into wire (because of its ductility) makes it a great mechanical choice for wire. And copper is highly conductive, that is, it has a low resistance to electric current flow. These two properties make copper an excellent choice to make electrical wire.
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.
tungsten
tungsten is a wire used in making filaments of the bulb.
How do you make a simple plazma arc using tungsten wire.
Nickel chromium wire with fiberglass insulation is used in very high temperatures.
An immersion electric heater usually uses nichrome wire as the heating element. Nichrome is highly resistive, and by applying a voltage, we can get it pretty hot. Nichrome is used as the heating element in toasters and on electric range elements as well as lots of other places.
copper?
It doesn't
Nichrome wire is commonly used for resistance wire for heater elements and it is a non-magnetic alloy of two elements nickel and chromium. It has high resistance and resists oxidation. The electrical resistivity is about 65 times that of copper.
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.
because tungsten is a high melting point and its melting temperature so high and long life
Yes the wire size is larger for that size breaker but will not effect the 30 amp breaker protection of that circuit.
