Understanding Vaping Coil Wire Basics

18th Jan 2018

V2 Trinity VaporizerIsn’t it time you understood the basics of vaping coil? If you’re happily vaping along with a premium 2-piece vape kit, you probably won’t need to know any of this. Truth is, you’ll only really need to know about vaping coil if you’re into rebuildable atomizers and all that they can do for you . If you’re interested in rebuilding your own atomizer, these basics are a must for you. Even if you aren’t, it’s good to know about vaping coil. After all, any vapour device we use will have one. Let’s dive in.


If you don’t know already, a vaping coil wire plays a very important role in your vapour experience. It will form the coil, which works to build up heat with the help of your battery, and transmit them to your wick so it can be heated. Once your wick, soaked with e-liquid, is heated, then that lovely vapour will be produced. It’s really at the core of an atomizer, which is itself at the core of why vaping works.

Important Terms

Before we go on to discussing the different types of coil wire, there are some terms you should understand. The first is gauge, which is simply the diameter of the wire. The lower the number, the larger the diameter is of the wire. Typically coil wire is somewhere between 22 and 32 gauge.

You should also understand the role resistance plays in this. Because as the size of your wire goes up, the wire’s resistance decreases. That means thinner wire like 30 gauge will have more resistance but will also heat up quicker than a 22-gauge wire. Lastly, you should know what ramp time is. This is what we call the time it takes for your coil to reach the minimum temperature needed for vaporizing your e liquid.


Different types of coil wire will behave differently to electricity and heat, and thus will have their own sets of pros and cons. Let’s take a look at the four most popular types and what each can offer you.

Titanium – Let’s start with the one that is least in use of the four we’ll cover. Titanium does have some strong points. It is really simple to work with and it does a great job in combination with most wicking material. Yet, there are concerns. Titanium is known to release a toxic compound at extremely high temperature, and it is hard to put out if for some reason it did catch fire. This isn’t a concern for the people that use it and swear by it, but it’s enough to make most people use the below wire types instead.

Kanthal – As one of the most widely available types of coil wire, you can imagine kanthal is very popular. Besides being so easy to acquire, it’s also cheap and easy to work with. Often this will be the starting point for anyone trying to build their own coil. The biggest point against the use of kanthal is that it doesn’t work with mods that have a “temperature control” feature. It can also be considered a little slow in ramp time compared to others. Still, it’s often the go-to wire type for vapers.

Nichrome – This type of wire is actually an alloy made of nickel and chromium. The points in favour of using nichrome is that it holds its shape really well, and it can ramp up quickly. On the downside, it’s that it does contain nickel that some people are allergic to, and it isn’t so easy to find, so you’ll probably have to search online to get it.

Stainless Steel – This type of coil wire has fans that swear by it. Using stainless steel will get you a very quick ramp time, and that’s a huge plus for many vapers. It’s also one of the easiest wire types to manipulate and create shapes, plus it holds those shapes well. The negative side of things for stainless steel is that it isn’t so easy to find. For some, the nickel content of it will also scare them off.

If you wanted a basic understanding of vaping coil wire, rest assured you just got that. You now know the role of vaping coil wire, some basic terms, and the most popular types of wire. What you do with that information is up to you. There’s a big vaping world out there and we encourage you to explore it.
