wire type equivalence for coils

[VAP8]

I am having a bit of trouble in finding the types of wires discussed about in here and other sites, nothing I have access to in China is referred to in the same way.
One online shop sells Kanthal wire, but has no info as to its other characteristics, like diameter, resistance per length, composition etc...

None of what you folks use in describing the wires is used in China, and I can't figure out what makes micro coils what they are. What is a micro coil?

I've bought 0.2mm and 0.3mm wire without knowing more about them than their diameters, experimented with that and based my coiling on the feedback I got while vaping, as well as the Ohm readings. I stopped using the 0.3 though (not enough resistance and tough to manipulate).

last I bought was a 0.2mm wire which indicated the composition (Cr20Ni80), however, I don't what it relates to, is it anything you guys use?.

Most people here use the wire on these specifications:

^ that's only for nichrome though, Not kanthal. Those are two different types of heating elements. I'll see if I can find the thread for coil sizes.

Here's a fact sheet posted from the following thread ( http://www.e-cigarette-forum.com/forum/showthread.php?t=518419
MICRO COILS - Selecting the right gauge wire to hit your target resistance) that talks about what makes a micro coil.

And suddenly I have something to go by~ I got the answer to the question I didn't know how to ask, thanks guys!

(I guess the outside diameter range in metric units is a typo, should be 0.14 to 0.165 in mm)

VAP8,

That outside diameter is for the coil not for the wire itself!!!

And for your original wire:
.2 mm is 32 gauge
.3mm is about 28 gauge.

Also, your wire is Nichrome80, which is a different composition than the nichrome60 in the temco data sheet above.
Some say the Nichrome 80 gives a much better taste because there is no iron in it.

No, the sheet is correct unless your using cm.

A .14mm inside diameter would be impossible to achieve

Here's some more wire type experiments I did

That clarifies the micro-coil mystery for me. So micro refers to the coiling, not the wire.
The "Nichrome 80 giving better taste due to no iron" bit is what the on-line vendors boast, can't say without comparing with the Nichrome 60.
So you guys talk in "gauge" to indicate the wire diameter? adding that to my vocabulary
Thanks for the diameter equivalence and experiment results, will save me trial time~ *&*

Yep, gauge refers to the size. This wikipedia article has a very useful table:

Would be less confusing if this darn usa would use the metric system, instead we get inches, miles, gallons, ect ect lol

I did my first micro-coil last night, as per info I received from you guys and this forum. I did it on my Russian.
28 gauge, 12 wraps, got me to 1.4 Ohms. It is indeed much easier and faster to coil with thicker wire sizes, (and also easier to practice acupuncture on oneself with them).
Surprisingly, it is very similar to the first coils I did when starting off, a few weeks back. I notice, however, that the glow is slower to come than the last coils I made till this one (higher resistance ~2.5 Ohms, bigger inner diameter, shorter length and thinner wires). I guess the glow is not indicative of the heat released, so I meshed it up with cotton wool, and vaped....
Note, this is not a dripping set up, it is a tank set-up.
I love the richer, thick and cool flavour I get at 5.5 watts, this is my sweet spot, in spite of the target 8+ watts everyone is doing and recommends.
consistent and yummy vape, this is.

Question: I am under the impression that micro-coils is used by most in dripping set-ups, just like sub-Ohming is, is that the case? or is micro-coils also used in tanks set-ups like I am doing?

Micro coils are very common in Russians/kayfun setups, a lot of people also rebuild clearo heads with micro coils.
