Kanthal is for use of rebuilding RBA's (Rebuildable Atomizers). Please use this product with knowlege and safety. Not recommended for beginners who are not familiar with RBA's.
Note: Please be extra careful when handling wire. Due to the nature of which this material is composed of as well as its size, there can be some residual tension and the wire can spring off the spool very quickly.
Specifications:
Kanthal A1 AWG28 - Approx 5.73Ω per foot
Kanthal A1 AWG26 - Approx 3.45Ω per foot
Kanthal A1 AWG24 - Approx 2.2Ω per foot
Kanthal A1 AWG22 - Approx 1.52Ω per foot
THE FINER THE WIRE = THE HIGHER THE RESISTANCE
The AWG 34 wire (0.15mm in diameter) produces HIGHER ohms over a SHORTER distance, as compared to the commonly used AWG 32 (0.20mm in diameter) which is slightly thicker, but would require more coils to achieve the same resistance.
TWISTING THE WIRE LOWERS THE RESISTANCE BY HALF
If you wish to use twisted wire, you will need to double the amount of coils to achieve the same resistance.
DIFFERENCE BETWEEN KW A1, A & D
When selecting KW for purchase please note the differences:
Kanthal A1: Max temp: 1399C, 1.45 Electrical resistivity at 20C ohms
Kanthal A: Max temp: 1349C, 1.39 Electrical resistivity at 20C ohms
Kanthal D: Max temp: 1299C, 1.35 Electrical resistivity at 20C ohms
As you can see Kanthal A1 has a HIGHER max temperature threshold than Kanthal A, and Kanthal A is HIGHER than Kanthal D.
In e-cig terms, A1 wire is slightly less likely to "pop" if a short or hotspot occurs. Although, the differences are most likely to be small.
