5 different types of wires are used in building coils for vapes. The first one is Kanthal which is easy to work with and has a good ramp up time. This is the most commonly used wire and has wattage only. The next one we have is Nichrome, also known as allergen. It has an excellent ramp up time and is easy to share. This one again has wattage only. The third one is the stainless steel. It has a fast ramp up time. With many grades of purity, it’s clean, crisp and flavorful. It works in wattage as well as TC. Nickel also known as allergen is the fourth type of coil we use. It’s easy to source but difficult to work with. This only works for temperature control. Titanium is easy to work with but hard to find. Though it only works for temperature control, it still gives you a clean and flavorful experience.
