Kanthal A1 is a ferritic iron-chromium-aluminium alloy (FeCrAl alloy)
rated for use at temperatures up to 1400°C (2550°F).
The alloy has high resistivity and great oxidation resistance.
It is typically used in furnace applications, such as electrical
heating elements in high-temperature furnaces for heat treatment,
glass, steel, ceramics, and electronics industries.
At present Kanthal A1 is the best coil material for ecigs.
The factors that affect resistance are:
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
Current: Determine the current (amperage) you need to heat your kanthal
