What is nichrome
Nichrome is a corrosion-resistant alloy consisting of 2 metals - nickel and chromium, and additives (manganese, sulfur, aluminum, phosphorus, iron, etc.). The alloy is resistant to temperatures up to +1300⁰C, and plasticity allows it to be used for the production of electric heating and resistive elements, various rolled products and wire (thread). Depending on the composition, nichrome is divided into certain brands.
Characteristics and properties of nichrome wire
The production of nichrome wire is limited to two main grades: X15H60 and X20H80. The characteristics and properties of each brand are different.
X20H80 is characterized by:
- Composition of 25% chromium, 75% nickel, 1% iron.
- Resistivity 1.13 Ohm mm 2 /m (for wire with a diameter of over 3 mm).
- Operating temperature 1250⁰C-1300 ⁰C.
The density of X20H80 is 8500 kg/m³, the specific heat capacity is 0.44 kJ/(kg K).
X15H60 is inferior to X20H80 in technical specifications:
- operating temperature - 1000⁰C-1100 ⁰C;
- composition - 18% chromium and 60% nickel;
- specific heat capacity - 0.46 kJ / (kg K);
- density 8200 - 8500 kg / m³;
The specific resistance of this brand is 1.12 Ohm mm 2 /m.
The low iron content of X20H80 allows the filament to resist corrosion and wear. Unlike X15H60, which is more prone to corrosion. However, this brand serves as the production of samples, the cross section of which is characterized by greater plasticity and a smaller area.
Benefits of winding your own evaporators
As mentioned earlier, the formation of steam occurs directly on the spiral and, accordingly, the larger the winding area, the more steam will come out of it.
The winding surface can be increased in various ways:
- when winding, use a thicker wire - the simplest, but extremely impractical option for increasing the area of \u200b\u200bthe spiral;
- the use of special forms of winding, due to which it is possible to increase the number of coils (turns);
- an increase in the area of \u200b\u200bthe frame itself, on which the spiral is wound.
If you increase everything at once, then the battery simply will not be able to overcome the resistance on the coils. This can lead to the fact that the coil will heat up unevenly, and its temperature will be too low and insufficient for the implementation of the vaporization process. Here, either the vape will not give out steam at all, or it will do it very slowly.
But, despite all of the above, these voltage and resistance indicators can be calculated if you know what temperature should be at the exit, the material from which the spiral is wound and the power indicators of the power source itself.
Well, for those who did not feel much love for physics lessons at school, there are a lot of all kinds of online calculators and specialized sites where you can calculate in a jiffy what diameter and what length the heating element should be in order for the vaping process to be of the highest quality. .
The point of implementing all kinds of coils is that due to the large number of coils and their tighter fit between each other, there is an increase in the very area that the vaper needs to get a good and tasty vapor.

Now we will tell you in detail how to wind the vaporizer for an electronic cigarette. Naturally, the nuances will vary depending on the type of winding, but the sequence of actions in any case remains unchanged.
There are also such unusual coils.
Regardless of the type of winding (pigtail, microcoil or art coil), the following tools will be required to implement this process:
- scissors or stationery knife;
- wire cutters;
- pliers;
- tweezers (preferably with ceramic legs);
- Screwdriver Set;
- a special winder, on which the winding process will be quick and convenient (in the absence of such a device, you can take a drill, a large-diameter screwdriver, etc.).
Of the consumables, you need wire and cotton wool for the wick. In our case, this is kanthal a1 (you can, of course, take material of any other thickness) and Chinese cotton, which, as a wick, is very convenient, since you can easily cut off a measuring strip from it and immediately stretch it into a spiral without additional manipulations.
The process of implementing kanthal winding is as follows:
- First of all, you need to thoroughly wash your hands so that our winding does not take over foreign odors, for example, food.
- Then we proceed directly to the winding. We take a winder, or what you will use instead of it, and begin to wind the wire. If you are making a spacecoil, then leave small gaps between the turns, in the case of microcoils, the turns should fit snugly together.
- At this stage, the microcoil is almost ready for use, and the spacecoil needs to be “springed” a little more so that it acquires the “correct” look.
We figured out the winding process. If you want to wind your atomizer with more sophisticated coils, then in one of our publications we talked in detail about the types of coils. There are also algorithms for their implementation.
6 steps.
The next step is the installation of the spiral. Here you need to take into account some nuances:
- First of all, you need to unscrew the fixing screws and push the edges of our spiral under them.
- After that, we adjust the position of the winding so that it is strictly in the center of the base and does not touch the nearby racks. Next, fix the spiral.
- Then it is necessary to harden our coils. You need to burn the spiral with short and not long presses on the electronic start key. We do this until the spiral is completely warmed up and turns red. If in some places the coils do not heat up, you need to lightly run them with tweezers.
It remains only to insert the wick into the coils and you can start tasting the new winding. And do you also wind your vape? Or do you have your own special secrets?
If you are an experienced vaper and like to control the entire vaping process, customizing the device for yourself, then you cannot do without a special wire for winding coils. Using such a wire and winding it as correctly as possible, you will definitely achieve the desired effect.
In the assortment of our store you can buy single-core and multi-core wires for winding spirals. We offer models with high conductivity, pleasant taste and abundant steam. Thanks to the correct selection of wire, you will be able to independently control the entire process and improve the quality of soaring.
Step-by-step instruction
Step 1
The first thing to do if you are going to make a spring with your own hands is to choose the material for such a product. The optimal material in this case is another spring (the main thing is that the diameter of the wire from which it is made corresponds to the cross section of the coils of the spring that you need to make).
By selecting material from an old spring, you will be sure that the wire is made of hardened high carbon steel.
Step 2
Annealing the wire for the spring, as mentioned above, will allow you to make it more ductile, and you can easily align it and wind it on the mandrel. To perform this procedure, it is best to use a special oven, but if one is not at your disposal, then you can use any other device that melts wood.
In such a stove, it is necessary to kindle birch firewood and, when they burn out to coals, put a spring in them, the wire from which you are going to use.After the spring is red-hot, the coals must be moved to the side and the heated product should be allowed to cool along with the stove. After cooling, the wire will become much more plastic, and you can easily work with it at home.
Step 3
The soft wire that has become soft should be carefully aligned and wound onto a mandrel of the required diameter.
When performing this procedure, it is important to ensure that the turns are located close to each other. If you have never wound springs before, you can preview the tutorial video, which is easy to find on the Internet.
You can use a screwdriver to wind a small spring.
Step 4
In order for your new spring to have the required elasticity, it must be hardened. Heat treatment such as hardening will make the material harder and stronger. To perform hardening, the finished spring must be heated to a temperature of 830–870 °, for which a gas burner can be used. You can be guided by the fact that the required hardening temperature has been reached by the color of the red-hot spring: it should turn light red. To accurately determine this color, also focus on the video. After heating to the required temperature, the spring must be cooled in transformer or spindle oil.
Hot steel colors
Step 5
After quenching, the spring should be held in a compressed state for 20-40 hours, and then its ends should be processed on a grinder to make a product of the required size.
What is nichrome and what is its value
Nichrome is a special alloy with a high concentration of chromium and nickel. The composition also includes iron, aluminum, silicon, manganese and other chemical elements, the combination of which gives the metal unique characteristics.
Heated wire jigsaw - a versatile tool for household use
Nickel Chromium Base Alloy Properties
The most common nichrome-based alloys are ferronichrome and ferrochromal (fechral). From them, the wire is obtained by drawing. The quality in its production is regulated by the current state industry standards. GOSTs 8803-89 and 12766 apply to a wire with good electrical resistance. Chromium gives hardness and strength to the metal, nickel gives plasticity. The maximum heating temperature is affected by the percentage of nickel in the alloy. The more it is, the higher the temperature, which can reach 1000-1300 degrees.
Finished products are sold on coils or in coils
The value of the alloy and products from it
Products made of an alloy of nickel and chromium have an increased resistance to electric current. This means that to obtain the same amount of heat generated, nichrome will need much less than another metal. Due to this, the weight and dimensions of the devices and devices in which it is used are reduced.
High resistance is provided by numerous parameters, the main of which is the brand of raw materials used for manufacturing, as well as thickness. The thicker it is, the lower the resistance, on which the level of heating depends. The metal does not burn, does not deform, does not lose its characteristics when exposed to high temperatures.
The useful properties of the alloy include plasticity, which allows you to give the wire the desired shape. The cross section can be in the form of a circle, an oval, a square and a trapezoid, with a diameter of 0.1 to 1 mm. The value of the alloy is also in the fact that, unlike most metals subject to corrosion, it does not rust, as it has anti-corrosion resistance to aggressive liquid and gaseous media.
Advantages of Chrome Nickel Alloy Products
The main advantages of nichrome wire, thanks to which it has become widespread in many areas of production, are in demand among inventors and home craftsmen:
- high heat resistance;
- anti-corrosion resistance;
- hardness, strength and mechanical stability;
- elasticity;
- high level of electrical resistivity;
- light weight;
- resistance to aggressive substances.
The only drawback of nickel-chromium alloy wire is its high cost, which does not affect demand in any way.
Where can I get nichrome wire
There are several options for how and where you can buy a nichrome product.
Today, in almost every settlement there is a reference for goods and services. By contacting her, you can get information from the operator, which organization sells nichrome and its contact numbers. Such information can also be found on the Internet. However, in this situation the chances of buying a normal product is almost zero
, because if anyone undertakes to deliver the material, then it will be only one and a half to two meters. Organizations mainly specialize in wholesale sales. But it's still worth clarifying.
If such a product is sold in another city, then you can use the “goods-mail” service. but This option comes with an extra charge.
for the shipment. You can buy wire in specialized stores. These can be "Radio Components", "Skillful Hands" and other similar pavilions. The sellers of such private shops selling various spare parts know each other very well. Therefore, if such a "private trader" does not have nichrome wire available, he can tell you where to buy it. By the way, you can find it in an ordinary hardware store. Spirals for electric stoves are made of nichrome.
Not a single settlement can do without the presence of a bazaar where you can buy anything you want. The most important thing is to carefully go around the entire market and you can even ask around the sellers. You can stumble upon such a product made of nichrome.
To find such a wire, one should somewhere find an old device
, for example, a laboratory rheostat. By itself, it is of no value, but a small amount of nichrome is wound around it.
Nichrome wire is a high-quality plastic product due to its excellent technical characteristics. It is difficult to buy or get it in any other way, but it is possible. You just need to take the initiative and try all the above methods.
Our country has never lacked "craftsmen". Wits and ingenuity have always been the hallmarks of a Russian person. One of the questions that concern many modern Kulibins is where to get the required amount of nichrome wire? But first, let's figure out why it attracts domestic "home-made" so much?
What is this material? In fact, this is a special alloy with a high concentration of chemical elements such as nickel and chromium (hence the name of the wire). It can have a section of the most varied configuration (circle, trapezoid, square, oval) and diameter (from fractions of a "mm" to several "cm").
Why is "nichrome" so valued?
Firstly
, it does not rust, and corrosion, as you know, is the “sore spot” of most metals and alloys.
Secondly
, the wire of this material is characterized by increased resistance to electric current. Therefore, in order to obtain the same amount of heat generated when included in an electric circuit, “nichrome” (in running meters) will need several times less than, say, steel. Hence the reduction in the weight of the device (device), and the possibility of miniaturization of the design (reduction in size).
Thirdly
, nichrome wire does not change its properties, does not deform, does not “burn” at high temperatures.
Fourth
, it is elastic, and it can be given any shape.
Where is this wire used? To be honest, it’s impossible to list everything, especially when it comes to production.Therefore, as an example, we note only a few options for its use in everyday life:
- machines for cutting foam plastics;
- devices for burning wood;
- heating systems for windows "auto" and rear-view mirrors;
- the simplest household heaters, better known as "goats";
- kilns for firing (for independent production of ceramics);
- for heating some types of metals (in home forges);
- homemade .
Where to get?
Here we come to this rhetorical question. Consider all possible options.
Buy
. There are also options here.
By the way, you can buy such a wire in a regular hardware store. Spirals for electric / stoves are made from the same "nichrome".
At the farmer's market. In every settlement there are places where people sell anything. Such "points" are called differently - "flea market", "collapse", "flea market". You just need to take the time and walk around, look around, ask around. It all depends on how much "nichrome" is needed. This is probably the most promising way to search, especially if you need a little material.
Conclusion
You can buy or otherwise get nichrome wire. You just need to take the initiative and try all the above methods.
Where to find nichrome wire
The easiest way to find nichrome wire is to go to a special store (vape shop). True, the nichrome thread is not cheap there, and for 1 meter you will have to pay a decent amount.
There are other options where you can find nichrome wire:
- radio markets;
- soldering irons;
- hair dryers;
- a heater made according to the type of fan;
- electric stove with an open spiral;
- the Internet.
The ability to detect metal in the radio market is not too great compared to a soldering iron (working or faulty). A soldering device can be found in the garage, or in the Fix Price store, where the product costs a penny. To find what you are looking for, the device must be disassembled and the wire pulled out. As a rule, the nichrome thread in the soldering iron is thin. Winding 10 turns on a pencil will help determine its cross section. The length of the wound wire reaches up to 2.5 m.
Options with a hairdryer and heater will cost more. The hardest thing is to get the wire out of the electric stove.
In order not to go to the market and not look for nichrome wire in the store, you can find information on the Internet about the sale of metal, or things containing it.
By the way, nickel in the composition of the alloy affects the price of the wire.
Where to buy wire for beading
This type of wire is the most popular among needlewomen. Wire with a thickness of 0.3 mm or 0.2 mm is mainly used for weaving trees, flowers, three-dimensional figures, sometimes it can be used to create original jewelry.
Beading wire of this thickness comes in several colors for a better work result. Allocate: silver and gold wire, red, green and blue, yellow and purple.
There are a lot of colors, so you can easily choose without worrying that the wire will be noticeable under the product.
Beading wire of this thickness easily passes through Czech beads No. 10, easily bends (while not losing its strength), perfectly holds and fixes the shape that was given to it.
Wire with this thickness is no less common among needlewomen. There are also many colors in her palette: black, copper, green, silver, red, gold, green, crimson, yellow, copper and several other shades.
Most often, 0.5 mm wire is used in the manufacture of trees, mainly trunks and branches.
This is a stronger wire. It is used to create beaded tree trunks and flower stems. This wire is also stretchy and flexible (because it's designed specifically for crafting), so you can easily shape it into the desired shape and fix it firmly.
Beading wire 1 mm thick has different colors, so it can always be matched to your finished work.
There are other sizes of wire that are not so common in needlework circles, but also have the right to life and use in work. These include: wire with a thickness of 0.18 mm, 0.25 mm, 0.38 mm, 0.4 mm, 0.6 mm, 1.2 mm and others.
How much does wire cost? I usually buy Gamma wire. In my city in the store, it costs about 40 rubles one skein. Probably the price may vary depending on the region.
What is nichrome
It is an alloy formed by two base metals, nickel and chromium. Moreover, the former sometimes makes up to 80% of the structure of the alloy. Also, other metals are introduced into the composition of nichrome, including iron, aluminum, silicon, etc. The operational features of the material include high electrical resistance, heat resistance, and ductility. Separately, these qualities are not something special for traditional metals, but the nichrome thread wins precisely due to their combination in one structure. For example, the same plasticity just makes it possible to produce alloy filament fibers, then using them in furnaces, where the working environment can be about 1,200 ˚C in temperature. In addition, depending on the purpose, the alloy can be additionally alloyed, which gives it new properties or improves its basic characteristics. So, to increase the working resource, nichrome is diluted with rare earth metal components.
What can replace the thread from nichrome
In the household, quite often there are problems with updating the heating elements in various electrical appliances. How to replace nichrome thread? The most suitable replacement is a working spiral, which can be found in irons, electric stoves, some models of kettles, etc. However, if it is also necessary to provide protection against electrochemical influences, it is recommended to use stainless steel. As practice has shown, a nichrome thread is endowed with the same resistance as stainless material, but in terms of oxidization it loses.
The calculation of a nichrome thread for 12 volts and 220 volts can be made using a special online calculator. To do this, enter the required parameters of the heater or electric stove in the appropriate fields, and click the "Calculate wire length for the heater coil" button.
For instance:
- Heater power - 20 W.
- Supply voltage - 12 V.
- Wire material - nichrome.
- Wire diameter - 0.1 mm.
We calculate and get:
- Wire cross section - 0.008 mm 2.
- Wire resistance - 14.4 ohms.
- Wire length - 0.1 m.

Winding resistance
When winding, the main criterion is the resistance in electronic cigarettes. This indicator can have both standard values for factory production (1.2 Ohm, 0.5 Ohm), and individual ones, for example - 0.7 Ohm, 0.3 Ohm. What does resistance depend on?
There are several factors:
- the length of the spiral or the number of rings - the “longer” the parameters, the greater the resistance;
- spiral thickness - the thicker the wire, the lower the resistance. It makes no sense to increase this indicator, since it will be difficult for you to wind the spiral, and it will also take a lot of battery power to warm up;
- material for the spiral - the materials differ from each other in their resistance, which is why the length of the winding, the number and diameter of the turns will differ.
Many vapers know that a large winding area due to many turns produces a lot of vapor. However, you do not need to wind as much as possible, your coil for electronic cigarettes will not fit in the atomizer, and the mod will not pull such a load.
The most common resistance value is considered to be sub-ohm, the value of which is below 1 ohm. Owners of mods on the board can even use 0.05 ohms. Now, such a low resistance scares few people due to the use of protection in modern devices.
Conclusion
The use of high-quality nichrome gives a lot of advantages to the user of a particular device or design. This material cannot always compete with analogues in terms of wear resistance, but protection against thermal shock and electrical resistance put it in a separate row already in terms of technical and operational properties. At the same time, nichrome thread should not be considered as a universal solution for the same electrical appliances. Again, some brands show their strengths most clearly as part of the cutting tool, and others as a stable conductor of the heating infrastructure. Endowment with certain properties largely depends on the introduction of additional modifiers. Actually, in its pure form, nichrome is almost never found today, since against the background of improving the characteristics of the target equipment, the requirements for consumables are also growing.Therefore, there is a need to improve the quality of the nichrome thread.
