33' (10 Meters) Spool Kanthal A-1 Round Resistance Wire - This item is NOT for beginners - See warning below

Kanthal A-1 is a ferritic iron-chromium-aluminium alloy (FeCrAl alloy) for use at temperatures up to 1400°C (2550°F). The alloy is characterized by high resistivity and very good oxidation resistance. For our purposes, it is used for making coils for rebuild-able atomizers.

Kanthal A-1 (as with most wire) is identified by Gauge (AWG). The table below contains the main relevant technical specifications for the different Gauges that we carry. NOTE: The  24 Gauge  is NOT (repeat NOT) recommended for any electronic cigarette application but has been requested by some of our technically advanced customers. The  28 Gauge  is also only recommended for very advanced users.

Average Diameter Heat
Resistance (68°F) Melting
Max Operating Temp
24 0.51 mm Annealed
0.17 Ω / in. 1500°C 1400°C
26 0.40 mm 0.27 Ω / in.
28 0.32 mm 0.44 Ω / in.
30 0.25 mm 0.70 Ω / in.
32 0.20 mm 1.09 Ω / in.
34 0.16 mm 1.76 Ω / in.

Resistance - 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.


Rebuild-ables are for experts, not average or beginner vapers. At a minimum you should have (and know how to use) a multimeter, know when a meter should be used and have basic knowledge of how electronic devices work. Without these things, these devices cannot be safely used.

Things to note:

  • A faulty coil can damage the atomizer device and/or battery
  • A coil should be tested with a meter and visually inspected before using
  • A good coil can easily become faulty with improper or excessive (which is improper) handling
  • If a coil "kinks" throw it away and start over
  • Even after testing good, if not properly installed, a coil may still become faulty at any time after installation

NOTE: Because of the nature and inherent risk these items are sold without instructions and there is no warranty offered for this product.

NOTE: When using this product, you should be familiar with Ohm's Law.
