For those of you building your own coils, or wondering what all the different types of metal alloys that go in your replaceable atomizer are and what they do, wonder no more!
I am about to break down the most commonly used metals/alloys that are used for your heating elements.
Here is a brief explanation of Ohms law and some basic fundamentals of electricity that will help you understand the rest of this break down: https://support.mtbakervapor.com/hc/en-us/articles/115006403048-Ohms-Resistance
Kanthal A-1- Is an iron-chromium-aluminium alloy. This is the most common alloy found in both replaceable atomizers and spools of wire for the DIY builders. It is referred to as a resistance wire, as it is best for getting the most resistance, or OHMS, if you will, compared to other metals. This is what started it all and is still widely the most popular for both big companies and coil builders. It can only be used in power mode (for more info about the difference in power mode and temp control mode, read this: https://support.mtbakervapor.com/hc/en-us/articles/115006162868-Temperature-Control-Devices) but there are some devices on the market that allegedly have a temperature control function for Kanthal. Good luck with that though.
Nichrome-80 - This alloy consists of two metals: Nickel and Chromium. The 80 represents the percentage of the Nickel, and you can easily figure that the other twenty percent is Chromium. Nichrome-80 has a bit less resistance than Kanthal, therefore sometimes more wraps or lighter gauges are needed to get the desired resistance, if you are building your own that is. You will rarely find this alloy being used in replaceable atomizers, as Kanthal is typically preferred. Some cool benefits of Nichrome-80 include the ability to get bright colors when heat treating your coil. For example here is a coil I made and colored using Nichrome-80, notice the blue and purple hues. The other cool aspect of this material is that it can be used in both power and temp control mode and it has been reported to give brighter flavor.
Stainless Steel/ SS316 - The name says it all! Stainless steel has a variety of different types, which will determine its carbon content, tensile strength, density, ETC. But for vaping, SS316 is what you are looking for. Much like Nichrome-80, SS316 can be used in both modes. temp and power, and is noted to have a brighter flavor, but it does tend to have more resistance, almost similar to Kanthal. Many manufacturers like Kanger and Joyetech have made SS316 somewhat standard in their replaceable atomizers, and it is quickly becoming more popular among many other brands as well. For those that build your own coils, SS316 is also a great choice if you are trying to get some good blues and purples when you temper them.
Ni200 - Pure Nickel baby. This wire is very soft and has only one application: Temperature control.
Something about the low resistance and molecular structure of Ni200 allows the computerized temperature control function found on some devices to be able to work. Part of the reason it is used for temperature control is that its resistance actually fluctuates greatly when heated, so you will often find Ni200 coils in 0.15 resistance, give or take a few tenths of an ohm. It is not popular among the builders out there due to its single application and low resistance, however it is noted to give a clear crisp flavor over the other temp control capable allows.
Titanium(Ti) - One of the more precious metals on earth, used in a variety of applications ranging from aircraft parts, advanced weapons and armor, automobiles and infrastructure. It has now found a place in the vaping world. Like Ni200, it is only used for temperature control, and has only a slight amount more of resistance compared to Nickel, and it's resistance fluctuation isn't as drastic. The only thing to be concerned about with Titanium is that it has the potential to give off harmful particles of Titanium Dioxide, but that is only if you "dry burn" these coils. This mostly pertains to the coil builders, but when you get that coil glowing red hot, microscopic pieces of oxidized Titanium accumulate on the outside of that coil and can be inhaled, which isn't all that good for you. Luckily Titanium is expensive and you usually don't see too many spools of Titanium vaping wire floating around.
Don't let any of that scare you, the pre-made Ti coils like the ones found in Evic Mini kit by Joyetech won't get nearly hot enough for you to have anything to worry about!
Keep in mind that there are other materials used to make coils, I've even heard of Tungsten wire being used, but if we are talking Pre-made or DIY, these are the metals and alloys you need to know about!
