	Nichrome - Wikipedia, the free encyclopedia
		Nichrome is a brand name for nickel-chromium resistance wire, a non-magnetic alloy of nickel and chromium., A common alloy is 80% nickel and 20% chromium, but there are many others to accommodate various applications or lower cost.
		Typically, Nichrome is wound in wire coils to a certain electrical resistance, and current passed through to produce heat.
		Nichrome is used in the explosives and fireworks industry as a reliable ignition system, such as electric matches and model rocket igniters.

	Heaters
		Assuming the Nichrome barely gets warm, move one alligator clip a few inches closer to shorten the portion of wire the 12 volts is being applied to.
		Remove power from the Nichrome wire and touch the meter leads to the places on the Nichrome wire where the alligator clips were placed in step 3 to measure the resistance of the minimum length of Nichrome wire.
		If the Nichrome wires are shorter than the length of the heater then you can stagger the Nichrome wires and connect them with copper wires.

		Insert the other end of the Nichrome into the small hole in the fuse and connect to the remaining wire by twisting and bending over as you did before.
		Take the nichrome wire, wrap it first around the stripped copper of the longer lead, then wrap about 5-6 turns around the INSULATED part of the longer lead and then wrapping around the un-insulated part of the shorter lead (look at Fig.1).

	Nichrome Wire AWG - Pyro Universe :: Community Forums
		I take the 40 AWG nichrome and with a sewing needle pierce it diagonally through the visco, being sure to pass through the powder core of the visco.
		Since it can prove to be a real pain to "sew" nichrome through the fuse of every firework you plan to e-fire, a more practical solution is to instead make your own igniters using visco and nichrome.
		I have 36 AWG nichrome sitting at home, and as the wrapping around the fuse and piercing the powder core work very well, you may want to use a lower AWG if you are wrapping.

	Electrical Igniters
		Nichrome igniters are easily the most reliable, and the best choice if time and materials are available.
		Nichrome wire can be found in old hairdryers, toasters, and even guitar strings.
		The end of the fuse is clamped directly onto a segment of nichrome wire, keeping the igniter away from the device.

	IRC's TanFilm vs. Nichrome Comparison Page
		The packaging, sealing and mechanical protection of nichrome resistor films is critical to prevent failures in a nichrome chip when subjected to moisture.
		Nichrome resistors were known to have moisture performance problems since their development by IRC in the 1950s.
		General Electric concluded that the moisture performance of nichrome resistors is dependent on the integrity of the package, commenting, "As a consequence, nichrome chip resistors will not survive even short-term exposure to moisture unless protected or placed in a hermetic enclosure."

	Richard Nakka's Experimental Rocketry Site
		Since this concept does not guarantee ignition unless the nichrome wire is actually contacting the propellant grain, later igniters had a small "ball" of propellant cast onto the nichrome wire.
		The nichrome (nickel-chromium, high resistance) wire serves as the heating filament (bridgewire), and is soldered to the ends of the copper wire leads using "stainless steel" solder.
		A nichrome bridgewire is soldered to a pair of electrical leads, similar to that used for the "straw" igniter.

		The second problem was attachment of the nichrome heater to the power bus wire.
		We felt that the compressibility of the woven construction would allow the nichrome to move and that there would not be enough force at the grid connection to hold the nichrome against the bus wires.
		A third improvement is the technique used to apply the nichrome heating wire.

		Nichrome, the commercially available nickel-chromium alloy, was employed in the hot-wire chemical vapor deposition (HWCVD) of Teflonlike thin films.
		The transient behavior was attributed to preferential oxidation of chromium and subsequent segregation of nickel.
		Substantial differences were observed in the behavior of the Nichrome 60 and 80 alloys, which was attributed to differences in the phase stability of these two materials.

		The thinner the nichrome wire (higher gage), the less amps it takes to heat and break it.
		Also, if the nichrome is wrapped, then the heat can not disipate as fast and it should heat up faster with less amperage.
		Assuming you used standard nichrome wire, 40 gage is 60.8 ohms per foot or 5.066 ohms per inch.

		When enough electricity is passed through nichrome wire, it gets really hot, which is why I use it.
		Set the time (if your contact is on the face of the clock at 6, and you are using the minute hand and you want the wire to get hot in 15 minutes, you put the minute hand on 3).
		And you would connect the blasting cap up to where the nichrome wire is at the moment.

		Nichrome wire is an alloy of nickel and chromium.
		Nichrome wire has a fairly high electrical resistance compared to something like copper wire, so even a short length of it has enough resistance to get quite hot.

		Before that, there was no wire that could stand red heat long enough to work in one." This statement is based on the knowledge of the 1906 patent date of the Nichrome wire, and the assumption that since it became standard use in most all electric toasters subsequently, no electric toaster existed before Nichrome.
		In the volume 2, #2 of hotwire we presented evidence that Hotpoint (Pacific Electric Heating co.) was advertising a flatbed toaster as far back as 1908 as well, presumably using the Nichrome wire.
		This method prevented the oxidation of the element, a problem which the open-air Nichrome wire was later able to overcome.

		I would also like to know why the resistance of a nichrome wire is constant and the resistance of a filament bulb will be varied.
		The resistance of the nichrome wire depends on cross sectional area, length, crystalline structure and purity, and temperature.
		For a wire of constant manufacture, all of these variables remain the same, so the resistance is constant.
