When it comes to electronic cigarettes, the coil is where the vapour is produced. You can also find the terms atomizers or atomizer heads. They typically consist of a small spiral of metal wire. Some coils use mesh, a set of connected strands of metal. The coil also includes some wicking material. This is usually a piece of cotton, but other options are possible, such as silica, ceramic fiber or rayon. Electronic cigarette coils act as a resistance element. When you activate the battery, the coil heats up and the e-liquid contained in the cotton gets vaporized.
In disposable or replacement coils, the wire and the cotton are encased in a small cylinder of metal. These coils fit existing pods and clearomizers. They look like a small metal encasing. When ordering disposable coils, you need to select the brand of your tank and choose the relevant coil. The wire and cotton are already in the coil. You simply need to prime the coil, by letting a few drops of e-liquid onto the cotton and you can start vaping.
How do I build a Rebuildable Tank?
Coil wire and pre-built coils are for rebuildable atomizers, such RTAs and RDAs or drippers. These tanks have a deck where you can build the coil. Building the coil amounts to rolling the wire and placing the cotton according to the tank’s design.
What kind of metal is used?
Coil wire is available in different kinds of metal from Kanthal to Stainless Steel (SS) to NiChrome (Ni80). You can get more information in the coil wire section. The same goes for cotton and wick material.
