So, for $6 wire (25ft/24awg), I thought why not. The wire arrived and was slightly dull silver in color and not shiny like some of the other Ti wire being sold as vape specific or"specialty". The color/appearance would be due to the TiO2 layer and was otherwise clean and not as oxidized as some of the reference pics I have seen.

I've outlined my experience below: 

1. I cleaned the wire with alcohol/cotton and wiped it dry before use. 


2. loaded the Steam Engine CSV for Ti grade 1. I could not find any other standard Ti CSV files for testing as those that have been discussed were pointed towards dead links. 

The setup was the following: Freakshow RDA; Wismec Reuleaux DNA 200; 
Settings were 35-45w with a 60w preheat, punch set to 5 (420 - 500 degF) 

The coils were 9 wrap/3mm-ID dual coils: 1 spaced set; 1 set of contact coils

With a temp limit of 420 degF: Temperature went to limit within 1 or 2 2second pulls. 
Bumping the temperature limit up to around 480 seemed to work better where I could take several (4 or 5) 2-3sec pulls, but the DNA 200 was pulling the wattage back some to keep it there. 

Neither set of coils seemed to have the perceived power of SSV Ti using the same settings. Also, the SSV wire hit temperature as I would have expected, when the cotton began to become dry from use, whereas this wire had the tendency to hit the temp limit quickly. 

Obviously I will need to order non-specialty Ti grade 1 wire from a few other vendors to know how Ti is going to perform. For me the SSV Wire works very well, but I would like to have a less expensive option.  Also, from what I have gathered, grade 1 Ti  is not commercially available as 100% Titanium and is only 99.2-99.5% pure.  I have seen the 100% pure and surgical grade descriptor thrown around by a several vendors. The surgical aspect would certainly appear to be simple marketing,  as all grade 1 Titanium is surgical grade as are several other grades of titanium. 

So for now, I'm going to leave this wire alone, at least until I find out if this is safe to use or not. 

two questions for you.

1) do you notice a significant difference between the SSV and tempco brand? in terms of flavor, temp stability, and durability?
2) do you find contact coils perform better, worse, or the same for Ti TC? i find slightly spacing all of my coils, even kanthal, seem to last longer. in terms flavor being muted due to contact coils. my theory is the tiny spaces in spaced coils don't allow the crud to build up  around the coil and choke off, or choke in, the vapor as the coils racks up mileage.

It's titanium, so it will be as safe as any other titanium.  TEMCo is reputable and sells high-quality (usually made in the USA) wire.  Their Kanthal, for instance, is made by Sandvik themselves.

You can e-mail them and ask.  They usually respond to e-mails very quickly.

ssv wire wire is great. i been using it for months. few extra dolllars, but they provide custom csv and have great customer service. it performs better than the other ti wire i tried . everyone has their own opinion so not everyone will agree but i love it and use it on everything . i got 50 ft for 30 bucks and i am still on the same roll since september when i got my first dna 200

Chunky, the temco provides the same flavor, at least to me, as the SSV wire. Temp sensing appears to be working fairly well with the slight increase in temp limit, 480 vs 450 for SSV. I haven't had time with the wire and escribe long enough to work out more favorable settings for performance. After I have more time to work with it, I can have a more detailed description.

I enjoy the spaced coils more so far. The flavor, vapor, and temp performance seems better, however, I need to work with the contact coils more before I can say definitively. I will say the spaced coils are way easier to build and use quickly.

Doing ones homework should be mandatory or at least logical. The SSV wire has been discussed and beaten to death, do a search on the ECF site. It's NOT grade #1 titanium, hence its own special TCR profiles. You pay more and get less, but folks simply ignore the facts. However, the news that Tempco is finally carrying G1 Titanium is great news, even better that's it's ANNEALED (soft)! The Rio Grande titanium (soft) has only been available in 24 gauge, which works great, but now there are more choices in gauge with Tempco. Breath whatever you like, if I'm doing Titanium, then I want GRADE #1, nothing less, especially a hyped grade 2, with whatever else is included. Finding the proper TCR for G1 titanium on SteamEngine is quick and easy.

blueridgedog thanks for your thoughts on the SSV wire

VapingBad thanks very much for the recommendation - I'll check them out once I'm back in the UK [smile]

Could you describe the circumstances of these ignitions? That is a scenario that I would like to avoid replicating. Thanks

Taking non-annealed ti and annealing it manually so it is not springy.  The end result may be uneven, and a hot spot may form when vaping...pop.

Ah, ok. Broken coil. Had a mental image of a chemical fire and class D fire extinguishers...lol

That's your experience, NOT a fact. Been annealing wire and vaping on it with none of the issues you state, for a long time, as well as many, many others.

And to Johan, now with Temco.com offering all grades of Titanium that is already annealed (soft), you should have no concerns.

Have not personally had any issues with Ti. Temco looks like good stuff, and comparatively inexpensive. Have been using Ti from Lightning Vapes (bit pricey), and Unkamen (dirty). Their wires are a little springy, but certainly usable. I'll get some Temco wire, been making coaxial (clapton) wire with stainless steel core and Ti wrap, some 30-32g that is annealed would make that easier.

I didn't find the Unkaman too dirty at all, barely anything wiped off on a vaportowel after a 99% alcohol scrub, but wire can vary from batch to batch. It's sold for jewelry so I assume folks use an ultrasonic cleaner anyways, been meaning to buy one. Main problem is I had to slow pulse anneal it, as is springy. Then I found Rio Grande, another jewelry site that folks recommended, and their 24 gauge was much softer, problem there is they did not sell it in 26,28 gauge. Now that Temco, a trusted vendor is selling annealed titanium in all the gauges I use, it will be a one stop shop. Should get my first batch from them this week, used them before for all my old Kanthal needs.

Will be interested to see how you like it. I emailed with the owner of Unkamen and he said his product will be shiny bright and clean as of his next wholesale order, so perhaps you got the new stuff.

On the Unkaman site they explain that the titanium is "acid washed", that's why the wire is dull, not shiny. Then these jewelry folks tumble their creations SHINY! Does not make a performance difference to us, but some were confused when it was not shiny like some other Ti wire. I don't know how the Temco Ti wire is going to look, they deliver slow for some reason.

The stuff I got was really dirty. Iso alcohol on a paper towel came out black on the first pass. The surface was rough to the touch. Took some scrubbing to get it clean, and I would prefer to not put that kind of exertion into a piece of wire [nono]. That's what prompted my communication with the owner.
