Just popped this post up for some discussion on some coil making with each of these two wire types. The reason I'm posting here and not the wicks n wires or atomizer mods threads is because I know that most of the members that read these threads (GG) have the experience with this and typically the response time is a little quicker.

Currently for resistance wire I'm using the Kanthal 32awg, I have about 100' spool of it, so basically that's all I've used thus far. I haven't had the chance to experiment with the Nichrome wire at all and was wondering if there was a major difference in the effect that these different wire types give off in an atomizer.

What brought this about was being that I have plenty of Kanthal 32 and like the lower resistance coil, I want to still make a lower resistance coil but have more windings to the coil around the wick. Currently I'm using a 1.7ohm coil that I built the other day with the Kanthal 32 and I was basically only able to get about 3 moderately tight turns around the double wick (approximately 3mm). It hits pretty good, but I think I can do better.

My logic here was going for a lower gauge wire, which is slightly thicker but still easily manuverable (I'm thinking a 22 or 18 gauge) so this will allow me to use a longer length to wind more coil while still maintaining a lower resistance ... and .... having more coil across the wick so the burn would be more even and more effective.

While researching a bit, I was looking into the different types of wire for use with high heat. I discovered that the Nichrome wire is 80% nickel and 20% chromium compound mostly found in heating elements such as hair dryers and such. I also discovered that the Kanthal wire has mostly iron, chromium and aluminum in its compound.

Anyhow, before I ran out and picked up a spool of Nichrome wire if anyone has had any experience with this wire type.

If there was any adverse effects such as, funky taste after tempering, headaches, chest pains, etc....

Thanks....

Peace-

I use nichrome and kanthal - 34 gauge is my favorite for most applications followed by 32 gauge. Thats going to be tough having lower with more windings. Why not try 4-5 windings of 34 gauge at 6V, you will be amazed - 6-7 windings at 7.4 V. 6V though is still my favorite - trying all of those will give you different tastes with same juice.


Note - 4-5 windings - 34 g @ 6V is great for Odyss. - absolutely awful with a bulli A-2 - must be something about GG and air because it only works for me like that w/Odyss or Iatty

I'm also interested in other ways to join Res and Non-Res wires. Has anyone had success in welding/soldering them together? I know of a guy who used crimping as well

I'm not positive, but I don't believe soldering would work that well (I was contemplating the same thing) reason the materials used in the solder / flux and not sure if the constant heating / cooling would loosen the particles for inhaling.

Brazing. on the other hand, great idea, but heating the braze with such small wires I'm not sure of.

Good ideas though.....

For more wraps NiChro is better, because it has lower resistance per foot.

32g NiCroA 10.16 Ohms p/f
32g NiCroC 10.55 Ohms p/f
32g KanthalA 13.96 Ohms p/f

as you see, if you want to make a coil with 1.5 Ohms resistance, the length would be shorter with Kanthal and longer with NiCro

Thank you R.D.

This is the answer I was looking for.

Thanks all for your input.

Peace-

R.D. - what's the difference between the NiCroA and NiCroC aside from the slightly lower resistance?

I believe Para was or maybe still is soldering them together. I don't have the post about it but he talked about it for the iAtty some time ago.

Also I have used crimp beads and I agree with Mr K they work pretty well with Nickel NR wire but they can cut soft silver wire. Also I dry burn every day to keep my coil clean and I have had an issue with that with crimped wires moreso with silver nr. I think the heat is melting the beads or the nr wire at the crimp point. It is a little faster once you get the hang of it but I find for longevity Nickel NR wire twisted works best for me.

For the OP I have used both and havn't noticed a huge difference in the 2. I will say thicker wire takes longer to heat up though so I would recommend against 2x guage. I guess 28 might work but I would still stick with 30 or so. Also I use to use 32 Kanthal for 1.8ish coils and got plenty of wraps.

Once I was cleaning my Ody wick on the stove without taking apart the coil. The coil was Kanthal A-1 32 AWG and I used .999 silver wire 30 gauge as NR wire.

What happened was that the silver wire melted at the joints, so the Kanthal and the Silver wire were soldered together.

Later I tried to replicate the effect with no luck :( the silver wire melted too much.
