Titanium wires

[soulseek]

Well the whole point of a microcoil is its increased effectiveness (i.e. required energy).
coils touch > larger surface area for thermal conductivity > coil heats up faster > more vapour + less strain on battery.
You won't see the same results once you separate them even a small bit. Then again maybe you don't need to if Ti wires heat up so fast.

imagine something simple super. Put a coffee pot on a gas. Let it burn without water for some mins until its bottom starts getting red. The smell is a metallic smell that you have to avoid inhale it. Then look the pot. Will you still make your coffee there? The metal is destroyed or to say it better, its not the metal you bought. Its surface is chemical different. Its not the same material any more. The oxides on it are not the metal itself, its a different material and its very dangerous like almost all metal oxides

The important thing is to not destroy the surface of a metal. And the most important is to use safe metals. Kanthal and nichrome are really unhealthy. They are not bio compatible materials.

The wraps don't have to touch on a micro coil. Just real close. Touching is (was?) good.

The term micro coil was used to describe the size of the coil compared to the typical coils being wrapped at the time I wrapped it.

Ok let me understand something though imeo brother:

No torching Kanthal before wrapping ?

No dry burning Kanthal ever ?

Do you really see a health problem with the very small amounts (about 1-1.5" typical) of Kanthal we use ?

Thank you.

Ah. So I took a look at the charts.

Seems like these wires would be ideal for low subohmers?

I like using 28gauge kanthal wires wrapped around 2mm diameter. 10 wraps gives me approx 1.1 ohms. I like em because they're fat and super easy to coil.

A titanium wire of equivalent resistance would have the same thickness as that of a 33gauage kanthal. Those are skinny skinny little wires and I hated working with them. Springy as hell and impossible to wrap nice and tight without losing my patience and degenerating into a heap of swear words.

Guess I'm just trying to see how I can get a reasonably sized coil at around 0.9 ohms, while keeping it reasonably sized and without having to use skinny skinny wires.

Not trolling, but genuinely interested. I have a godawful hoarding tendency and I wanna be sure before I start buying spools of them.

as superx said, no reason for coils to touch each other. Coils have to be close each other. That way, the heat is bigger to the specific points.

By touching coils each other has no meaning to me because a coil like that cant produce smoke. The smoke cant escape between coils. That also means that microcoils's threads dont touch each other, they are just closed.

As for metals and plastic deformation:
a) is there any present? There needs to be some stress applied when you're heating it for any sort of dislocation, and there isn't that much in this case.
b) does it matter? are these metals dangerous in this case? They harden steel by plastic deformation after all...

who said that these wires are skinny and springy kiwi?

Ah.

I'm just gonna stop being annoying, wait for your chart and prepare to buy a whole bunch to try.

Btw, I hope you'll be having a US distributor! Sure would be nice to save on shipping cost and wait time

Ps thanks for being so patient and taking time off to answer my questions.

I'm kind of confused by the claim that the fumes of the alloys Kanthal and Nichrome are dangerous, and that we shouldn't heat the wire red hot. Aren't those alloys used in toasters, hair dryers, space heaters, stoves, and ovens?

kiwi, I never get tired answering questions. Be well

Yes... we do use them a lot and everywhere, but we don't inhale their steams

JMHO

 

[imeothanasis]

sure Jerms. But we dont vape on these wires. Also we dont inhale the fumes directly to our mouth, coils are away from our body and our nose, most of these wires are in a closed environment like other metal or glass etc.
Also fumes are not the important thing here.

What I understood from imeo that oxidization is the bad thing, but this is almost impossible and impractical. A really small not even complete dry hit would oxidize it and then we have to change the wire? That's really impractical.

As for fumes I already said it and I will say it again. I don't think we are reaching temperatures where a big amount of kanthal fumes even if they were proven bad are getting into our lungs. Waiting on a bus stop is worse in my opinion. But that's just me.

I see.. I think. I was under the impression that the issue discussed was fumes from the heating wire glowing. That confused me, because a space heater blows Kanthal or Nichrome wire that's being heated almost white hot into the air, directly at us.

Since I misunderstood what the dangerous part is, could someone explain to me what the safety issue is with heating the wires we use?

 

[Jerms]

What I understood from imeo that oxidization is the bad thing

That I'm confused by too, because I would think stove elements and space heaters that don't have enclosed heating wire would oxidize as they continuously are heated to glowing and cooled, and I've never heard of health problems related to that. And hair driers too that having an exposed heating element that that blows the resulting air directly at us.

 

[imeothanasis]

oxidation is oxidation aal and its going straight to our body. If you think that the time you need to change a coil is more precious than your health, its a choice and I cant argue on it

I try to find the right english words for what i know about metals, alloys and the influence of heat to the alloy.
Everytime when a metal is heated a decarbonisiation started. Decarbonisation means, that carbon flue out of the metal and the wire changed his alloy. Maybe Imeo means this with oxidation? So this process started from the outside of the wire and grows to the core, the longer and hotter it gets.
That means, that you probably get another alloy the more you heat the wire, wich is not always healthy.
The decarbinisatioted surface can get fragile and unhealthy vape with Carbon or other ingredients can be inhalated.
I hope i could help a little to clear this.
I work in a steel plant and heating and decarbonisation of blooms is a big problem, thats why i know a little bit about it.

 

[CaptSteve]

Guys the reason we use kanthal till now is the fact that it's a material that resists surface oxidation at high temperatures.

Have a read please

Kanthal APM

I think we're drifting away however from the purpose of this thread. It's all about Titanium wire and how much better it is over kanthal or nichrome

 

[steliosss]

True Captain!!
The point of our conversation is not if NiChrome or Kanthal are good or bad.
The point is that Titanium wires are better

So let's start.........
