Getting to know the types of wire used in vaping
Vaping Wire Introduction
The goal here is not to overwhelm you or mire you in technical data but to give you a high-level overview, and just maybe help you decide which wire type suits your vaping style best. The focus will be on single strand wire, I will try to keep this as simple as possible.
There are some basic characteristics that apply to all wire, regardless of the composition of the wire.
The first basic characteristic of any wire, vaping or otherwise, is the actual diameter of the wire which is commonly called the wire “gauge” and expressed as a numerical value. The actual diameter isn’t really important. What matters is that as the wire gauge number increases, the wire diameter gets smaller.So, 26 gauge wire is thinner than 24 gauge but fatter than 28 gauge. Common gauges of vaping wire from smallest to largest diameter are: 32, 30, 28, 26, 24, and 22. There are others of course, even odd number sizes.
Second, as the wire size increases the wire resistance decreases, and generally it takes longer for the wire to heat due to the larger mass of the wire. Thin gauge wires like 32 and 30 will be higher in resistance but will heat faster than 26 or 24 gauge wire.
You may have heard the term “ramp time”. Ramp time is the time it takes for your coil to heat to the temperature required to vaporize your e-liquid when you fire your mod. Ramp time is generally more noticeable with exotic multi-strand wire coils like claptons, but as wire size increases ramp time can also become more apparent with simple single wire coils.
In basic terms, temperature control mods rely on a characteristic of your vaping wire to chosen because of their Temperature Coefficient of Resistance (TCR).
OK, I promised to keep it light, so here goes:
The TCR of the vaping wire is the increase in resistance of the wire as temperature increases. The mod knows the cold resistance of your coil, and the material you are using. The mod is also smart enough to know that when your coil rises to a certain resistance (as temperature rises) that the coil is too hot, and it reduces the current to your coil as required to prevent burning.
Kanthal is ferritic iron-chromium-aluminium alloy with good resistance to oxidation, and commonly used for vaping in straight wattage mode. Kanthal is a great place to start if you are just getting into rebuilding, dripping, etc. It is easy to work with yet stiff enough to hold it’s shape when formed into coils, which comes into play when you wick your coils. Kanthal is extremely popular, and I still use Kanthal wire as my primary wire when building single wire coils.

Another type of wire well suited for wattage vaping is Nichrome. Nichrome wire is an alloy composed of nickel and chromium, and may also contain other metals such as iron. Fun fact (maybe – Wikipedia): nichrome has been used in dental work, such as fillings.
Nichrome behaves very much like Kanthal, but has a lower resistance and heats faster that the same gauge in Kanthal (faster ramp time). Like Kanthal, it is easy to coil and holds its shape well when wicking. Nichrome has a lower melting temperature than Kanthal, so you need to be careful when dry burning your coils — they will burn open if you aren’t careful, and I’ve done it. Start low and pulse the coils. Don’t rush into it and hit them with max wattage while dry.
One other possible downside of nichrome wire is the nickel content. I have used it, but folks with nickel allergies may want to avoid using nichrome for obvious reasons.
Nichrome is less common than Kanthal, so some may need to shop for it online.
-Faster ramp than Kanthal
-Easy to work
-Lower melting point
Stainless steel is the most unique of the wires we will discuss here: it can pull double duty and be used for straight wattage vaping or temp control vaping (if your mod supports it — older mods do not). I have used dual-coil stainless steel builds to review TC mods since I can use the same build to test either mode. It really makes life easy if you switch between TC and VW often.
Stainless steel wire is an alloy composed primarily of chromium, nickel, and carbon. There are many variations (grades) of stainless steel, expressed numerically. Again, in the name of simplicity we won’t get into the differences between grades. The intent is to compare and contrast with other types of vaping wire. I personally use 316 which is the medical, pharmaceutical and food grade.
Stainless steel is easy to form and holds its shape well. Like nichrome, it offers a faster ramp time than Kanthal.
