Kanthal vs NiChrome

What is Resistance Wire?
Resistance wire is a high-resistance electrical wire that is often found in industrial applications including electrical ovens, toasters, and heating elements. The two major types of resistance wire are Kanthal and Nichrome wire.
Kanthal is a ferritic iron-chromium-aluminum alloy that can be in high temperature applications. It is often used in large, industrial applications and chosen for its high resistivity and excellent oxidation resistance.
Nichrome is made from nickel-chromium alloys is generally only used in temperatures below 1250°C. Nichrome has a slightly lower maximum operating temperature than Kanthal and operates best applications such as hair dryers, toasters, and kilns.

Corrosion, Rusting, and Oxidation
Resistance wire does not easily rust or oxidize, even in extreme environments. Kanthal is often chosen for its excellent oxidation resistance. It can be exposed to sulfuric compounds and not corrode quickly, making it well suited for corrosion resistance in hot states. Nichrome has similar properties but oxidizes more quickly than Kanthal in sulfur-containing atmospheres.

"Annealed" vs. "Half-Hard"

The terms "annealed" and "half-hard" refer to the temper of the metal, or the condition produced by mechanical treatment. Annealed wire can be shaped and cut easily, making it relatively flexible, soft, and bendable when pressure is applied. An annealed surface is achieved by exposing the metal to high heat and allowing it to cool slowly. Half-hard treatment refers to rolled and drawn wire.

Temperature Ratings

The Maximum Operating Temperature refers to the highest temperature the wire can withstand without suffering damage. Kanthal wire can operate up to 1400°C (2550°F) safely, while Nichrome wire has a melting temperature around 1150°C (2100°F).


The more heat the wire generates, the more resistance it creates. Resistance is affected by volume, diameter, and the length of wire. The longer the wire, the higher the overall resistance. Thinner wire has higher resistance than thicker wire.

Thermal Expansion

Resistance wire expands in diameter and length when exposed to high temperatures. All resistance wire has different reactions to heat and will expand different amounts. To determine the expansion of either Kanthal wire or Nichrome wire, check the specifications of the wire. The expansion rate and flexibility also depends on the diameter, or gauge, of the wire.

Microcoil Cotton Rebuild

Heres a basic guide on how to Microcoil on a Kayfun Lite atomizer. I personally suggest using a microcoil rebuild, as it is very simple to build, and easy maintenance. All you need to do is just dry burn every few days and replace a new cotton. Make sure you have high quality Kanthal wire so it wont break easily, and use 100% Organic Cotton balls you can get from your nearest pharmacy or chemists.

How to Dry Burn

Once your coil starts to have a burnt taste or you get that smelly unusual tasting vape, or your atomizer starts leaking and popping, you know it is time to do a Dry Burn. Usually every 2-7 days, you will need to do this regular maintenance. Some even do it everyday to get that 100% taste. It is a process where by you will have to remove all of your cotton ( if you are doing a micro coil ), dry burn your coil, and renew your cotton. Make sure you use high quality kanthal wire, so that your coil does not break easily. High quality Kanthal Wire can have you do Dry burn maintenance for up to a month or more, so you wont need to recoil all the time. Just Dryburn, replace the cotton, and off you go!

D.I.Y Atomizer Rebuild

How do I rebuild my own Atomizer?

Here is a basic step by step guide I had put together today, it will take you at least a good hour to start with

What do I need? Fibre wicks, coils, and some cutting tools...

NOTE : Put the rubber ring into 1 end of the coil only. This will isolate the + and - to the battery.

Note : Twist, bend, and break off the coil.

There you have it, a brand new atomizer you rebuilt yourself!
Just 2-3 times practice will make you a qualified Atomizer Rebuilder for real. Email me for questions or more info.
Good luck!
