Titanium wire, vaping and safety

[FlexibleAsARock]

Has anyone tried this Sweet Spot Vapour stuff? SSV? They're on the dna 200 early adopters forum, and apparently they've done a lot of work making a custom wire with a special TCR. Based on Titanium but.. different somehow.

But at $1/foot ($33/10m), I am struggling to understand what could be so much better about it than regular Titanium or especially versus Resistherm/Alloy 120.

From their website, it seems the main work they've done is to change the Titanium flat TCR to a somewhat curved one. They claim this is better, because the increasing resistance at "optimum temperature" reduces strain on battery/reduces power requirements. They also say it works well with mech, VW as well as TC mods - and of course they've got a custom dna 200 profile to make best use of it.

It all sounds a bit doubtful to me, and if I'd only seen their website I'd be comfortable writing them off as snake oil, like the $1/foot GPlat wire 'revolutionary vaping wire' that turned out to be SS317 welding wire!

However I have also seen them on the DNA 200 forums and there's no doubt they're highly technical guys with a whole lab worth of test equipment. And it would be easy to validate that they've changed the TCR of Titanium and if they have, that's at least proves they have some technical nouse (unless it turns out it's just some other grade of Titanium that already has that curve..)

Anyway, anyone here had experience with the wire?

I have no useful info other than I bought some of this sweet spot Ti, the .04 mm version and made dual coils for my velocity clone on an Ipv4s. The wire is very clean and shiny. I didn't see any residue at all on it when I rubbed it with tissue so I cut a piece and started coiling.
Made myself nicsick with 6mg nicotine 80vg juice in about 30 minutes, was trying to get the vape to as warm as I like but didn't find that spot yet. Flavor was good but even at 572F it wasn't as warm as I would have liked.
I'll try it again this evening

Guess I should add my build was dual 6 wraps of 26 gauge. Ipv4s read and locked @ 0.149 ohms

Well then, I guess I can't really see the benefit or detriment of any particular gauge outside of the length of time necessary for the coil to cool. Even that is manipulable by drawing air over the un-charged coil after releasing the fire button I would think. So many variables, so little time...

I pretty much choose my gauge (28) based on what I like to work with. I'm too lazy to deal with heat flux and so on

@TheBloke I have edited my post to reflect that with the 32ga, I can do a DOUBLE coil of the same properties with the same heat up/cool down, with an amp draw of only 8.15. Doing that with 26ga would require 24 amps. I can only assume that 200mm² vs. 100 of surface area is going to produce twice the vapor, so more flavor? I get my initiative to build using thinner gauge (ie more surface area with less heat capacity) from this very well written post on the subject:

My thoughts about sub-ohm and latest VV/VW devices... | E-Cigarette Forum

I am also assuming (knowing full well the dangers of THAT) that the longer ramp up and cool down of thicker gauge may result in a higher degradation of the juice in the wick in proximity of the coil? My experience with Vivi Nova's definitely showed me that "browning" of the juice in the tank via heat from the coil severely muted the juice, to the point that the last third of the tank was so muted, and so indecipherable as to the original flavor, that it required dumping.

As far as flavor vs. gauge, other than the assumptions above, I have no experience. I am waiting on the proper equipment to use Ti, and will play with it once I get it. I'll need to order some 26ga Ti to compare flavor. I have some subtle and complex juices that would really show me the difference. Should be interesting.

Thanks for the link to the thread, it was a good read. I wish I had read that when I first started vaping, many months ago! I started just at the time that sub-ohm tanks were becoming a big thing, so I had that misunderstanding that sub ohm = better for some time.

Personally I am not bothered about amp draw, or battery life. I have many mods and many many batteries, and 95% of my vaping is at home where I have easy access to both.

You do make a good point about residual heat. I suppose it can't do tank juice much good to be heated and cooled a lot. So the theoretical perfect vape would reach desired temp instantly, and then cool back down to room temperature instantly after the vape.

I'll try some experimentation. Though like with @KenD , I mostly go with what is easy. I suck at coil building, I always have problems - broken wire, shorting coils, etc - and when I do get it to work I can never guarantee good flavour, so I've mostly given up trying to do anything unusual or fancy. Thin wire might not be too difficult as long as it doesn't break - eg with Lemo style under-screw deck - because it's less likely to be too big for the RTA. Though I worry about deformation when I adjust the wick.

Anyway I'll try some untwisted 29G Resistherm and see if I can notice any difference. Thanks for all the info!

FYI I just ordered some 26G Ti from 3FVape: Ti Grade 1 26 AWG 0.4mm x 10m Titanium Heating Wire for RBA

I was ordering stuff from 3F so I thought I'd throw in a spool to see how good quality it is and test its TCR.

I thought it might be a bargain price, but it's not - $5/10m which is slightly more expensive than Crazy Wire (excluding shipping.) Factoring 3F's free shipping around the world it might be an option to consider for non-UK/EU users, if it turns out to be decent quality.

@druckle is there any easy way to confirm a wire is Grade 1 as it claims? If I test the TCR and it's 0.0035, is that good enough? Anything else I can do/look for in the wire to confirm it's Grade 1 and appraise its quality?

@TheBloke did crazy wire publish their Ti datasheet?

What Sweet Spot Vapor claims about their "proprietary annealing procedure" is pure technical BS. Unfortunately there is always a company willing to exploit the trust of customers and sell fantasy at a high price.

This sort of thing drives me up the wall.

And, if wire is their thing, what`s all the juice and stuff on their site

Not yet. He replied on Thursday and said he'd have it on the website 'soon' so I guess next week. I'll check and post when I see it.

Unfortunately, short of costly chemical analysis, there is no way to be sure of the alloy grade. It's a case of trusting a supplier.

In other words, we are screwed.

I'm playing with same pair of coils I mentioned earlier, 6 wraps 0.149 ohms not able to get it up to a temp I like even at max 572F on velocity clone.

Would more wraps on smaller gauge Ti wire help, went from air flow open to airflow almost closed but the flavor is great as long as i stay at least 30 joules and max temp
the flavor is great but it doesn't have the warmth I'm used to with kanthal even at 100 joules an 572F on Ipv4s on Ti mode

Wow I need 3mg nic juice or maybe 0 if I keep at this

My 26 and 28 ga titanium from Unkamen were pretty clean. Not so with the 30ga which was very oily.

I have a very similar experience with the Zipipf wire. The 28 and 26g were similarly dirty - like others have reported - but the 24g is almost clean (2-3 wipes with alcohol/vaper towel and it's perfect).

Interesting discussion about gauge, flux etc. Like TheBloke I kinda suck at coil building, so I go for what's practical and tastes good enough. Twisted & clapton never did it for me (style of vaping?), I always wondered what I was missing. What's funny though is that the 24g Ti1 and temp mode don't give the same residual heat problems as I had before TC. Or maybe not funny, as TC will halt the constantly rising temp that contributes to the residual heat. There is no sizzling/coil gunking at the moment with 24g over what I'm used to with 28g.

Hello guys, is there a chart for the sxmini m to work with titanium 26g in ni200 mode?

I've heard that 26g stealthvape titanium doesn't work so well with the ti firmware of the yihi chips...
Is this true?

Something like this but for the sxmini

Go up to 120 joules in Ti01 mode and see. Or go back into Ni200 mode with a Ti build. It'll be hotter even tho it only goes to 50 joules.

Hello Steven Gerrard, love your work!

I haven't done this sort of chart for the SX Mini M yet. I plan to do so shortly. When I vape Titanium coils on an SX Mini M in Ni200 mode I set it to 140-150°C, ie lower than a DNA 40. That seems to work OK, until I do the formal testing.

I have been told that using the new Titanium mode does work OK, but you need to set the temp higher than you want, eg 500°F for 450°F or maybe 265°C for 240°C - that sort of offset.

Anyway I will be doing some proper probing of the SX Mini M soon, next couple of days, and will post the results here and in the SX Mini M thread.

I am having really good luck with Crazy wire from Vape Atomizer Mesh company in your country. It has some machine oil on it but one wipe with alcohol and its gone. It is vacuum annealed Gr1 price is right and seems to last great. My coils are going on 3 weeks on the STM's and still vaping as good as new I haven't even rewicked them yet. It is a little springy but the price is right and very nice people to work with. I will definately order from them again. I have only used the 26awg comparable. I haven't tried any others but I have 6 using that and I am very happy with it. The resistance is holding right where I built them 5 wrap 3mm .27-.28 I am thinking of ordering some 29awg because I noticed when I wrapped an 8 wrap contact coil which came out at .43 the Ti mode worked very will at 420 and 16J. It was actually stable which for me it is all over the board with a .27 coil. Very stable at 270-275 14J in Ni mode though. Shipping would be cheap for you also. You really can't beat their price.

I would like to see that. I would also like to see PB with his new equipment check the temps with Ti in the 2 different modes. I get the same sort of vape at 270-275F in Ni mode and 460-480F in Ti mode as I do with nickel at 390 in Ni mode about 14J for all. I really think the temps must be pretty close by performance.

FYI I have the same temp equipment as Busardo. Although last I checked, I've got better probes I noticed he's s stopped showing the actual probing in his videos, just the graphs, so I can't see if he updated the probes again. But last I checked he had a huge stick thing which must have a terrible response time.

Cool, glad to hear it. FYI I don't think it's machine oil, or at least it wasn't in the spools I got - it's graphite. Still needs to be cleaned off, but it comes off really easily.

I'm pretty pleased with the CW wire. It sounds like the Stealth Vape stuff is more annealed, hence less springy, which is always nice. But the CW stuff is more than usable and an unbeatable price.

In a week or so I'll have Titanium from Crazy Wire, Stealth Vape, Zivipf and also 3FVape, so I might do a few comparison shots and charts I'd like to do a video at some point, but I always say that so god knows if I ever will..

Maybe I'll even order some US stuff at some point so I can really compare all, or at least most.
