Kanthal A1
Kanthal A-1 is usually used for high temperature furnaces in the heat treating, ceramics, glass, steel, and electronic industries. Other common applications include: heating elements (hair dryers, ovens, toasters, kilns), model and high power rocket motor and recovery ejection charge ignition, heat sealers, poly cutters, foam cutters, resistors, rheostats, current-temperature controls, pyrotechnic ignition, electronic cigarettes, lab inoculating loops, release mechanisms, ceramic support in kilns.
Diameter: The thinner the wire (higher gauge number), the higher the resistance per foot. The thicker the wire (lower gauge number), the lower the resistance. Length: The longer the wire, the higher the overall resistance. The shorter the wire, the lower the overall resistance. Temperature: The more heat the wire generates, the more resistance it will create.

Flat ribbon wire
Ribbon" just means that the wire is flat instead of round. The primary difference between flat and round wire is the amount of surface area for a given volume. This is similar to why cooking stoves have flat tops. Why use flat wire?
Produces More Vapor
Get more vapor from each draw. There is more contact area between the heat source and whatever is being heated.
Easier to Wind
The flat shape of the wire makes it much easier to wrap around and cover the wick.NOTE: Sharp twists in ribbon Kanthal can cause tears, rips, warping, and other kinds of mechanical damage. Avoid twisting the wire ribbon  when winding coils.The only areas where twists are unavoidable are at positive and negative screw terminals. This is because you should have your ribbon wire flat
horizontal) against the screw head, as good electrical connections require good mechanical connections. However, this means you may have to twist the wire in order to wrap it around the wick.
Eliminates Hot Spots
A common issue that occurs when winding coils on atomizers is areas of uneven heating, or "hot spots." Hot spots can significantly shorten the coil life. They cause parts of the coil to expand and contract at different rates, which wears out the coil much more quickly.It can be frustrating to find a hot spot after taking the time to carefully wind a coil. Flat ribbon wire makes this less likely to happen.
