TC beyond Ni200: Nickel Purity, Dicodes; Ti, SS, Resistherm NiFe30; Coefficient of Resistance

[JimScotty0]

The TCR of Invar36 is about 0.00117. So it is possible that the unknown wire is Invar. But this is just one parameter.

Mystery Wire solved! Maybe?

I have been doing some research and I do believe the newly infamous NiFe52, aka NienFethal wire I recently received from UnkamenSupplies and have been evaluating is Invar 36, also know as NILO 36, Pernifer 36, and Invar Steel as @TheotherSteveS thought it might be. We also do have some specks for it as put together by @vapealone on his "NI200 NILO Alloys" spreadsheet tab as NILO 36. The TCR value listed is extremely close to my testing listing the TCR value as .00118. My final TCR number was .0017 and what I have been using. You can find @vapealone's spreadsheet here:

High TCR Allows Listed as NILO 36

More information about NILO 36 here:
The NILO® and NILOMAG® Nickel-Iron Alloys

The Wire Wizard doesn't have it listed, but maybe @Dampmaskin can add it if gets a chance. This wire really isn't bad for TC and now if this is truly what this wire is called we can venture further for the adventurous. Another advantage is that its Nickel content is only around 36% so for those with a sensitivity or dislike for Nickel it may be an alternative wire to use.

More info on the recent 24awg NiFe48 build:

Firstly, I was right, one of the screws was not sufficiently secure. Its leg snapped. As with SS you know when this has happened: "a puff of smoke, a cloud of dust, and a hearty heigh-ho-silver" (Lone Ranger reference). Awareness that a coil leg has snapped.

So, I rebuilt, taking care to secure the wire. Still a great vape but now the expected values show. Steam-Engine predicted 0.15 for 7-wraps. I got 0.18 on the defective build but now 0.12 on the ohm reader, device, and eScribe.

And of course eScribe now reads the Temperature properly. Onwards...

to save me the time of searching in the thread. stainless is safe to dry burn right? i would assume so as u can use it in non tc mode.

Yes, absolutely safe to dry burn. In fact, my Mantra has been 'burn that sukkah'.

If you do not dry burn SS you are highly likely to get the snapped legs I mentioned a few posts ago.

well i burned that sukkah XD

(..). What's the consensus on SS430 in an SXJ with TCR firmware?
(...)
Also just ordered a ton of Rayon (might have ordered more than I ever need, but that's the beauty of it).
(...)

I am also interested in the findings on the SXM TCR firmware (if that is what you mean) not only on S/S430 but in general.
ATM I am running it w/ STM/UD's 316L/Rayon combo and I think I like it though I might need a super accurate temp probe to check the coil temp when locking resistance

BTW, I have found that I quickly loose temp control quality/reliability on both the DNA200 and the SXM with contact 316L S/S means that after some perfect vaping the live ohms want to go higher and higher than they should even though the cold ohms are constant. And after a quick cleaning and re-wicking everything goes back to normal.
Having no better idea I have started to blame the gunk creating some thermal insulation between the coil and the liquid that combined with the thermal mass of the 24ga wire and its low TCR can easily mess up my vape.
To test this idea I have switched to (less gunk prone) spaced coil to see what happens



A bit of a show off
I have done a battery analyser on my new shiny recently (the mod was posted here before/after paintwork) and have found that apparently Evolv didn't expect any DNA200 mod with battery capacity above 20Wh
The energy usage curve has hit the bottom border at 20Wh and could't go any lower Luckily, the numbers could

Since my early venture into NI200 and TC, I started using spaced coils and have not changed with any of the other TC wires. I know some have had good results with contact coils, but I would rather not bother having to deal with any variances with any shorting that may occur if not oxidised properly. Any slight short may not mean anything for non TC vaping, but with TC it is another consideration. The spaced coils have been working well for me and easy to clean.

@vapealone I have run 430 SS, 316, 316L, and, NiFe48 on the SX Mini J successfully. When I first saw your question my thought was, what's the TCR of that wire. Almost immediately "138" came to mind, which says I ran enough of 430 to memorize the TCR. (0.00138)

The other prominent number is 405, expressed on the SXM TCR as 0.00405. Done! [emoji18]

i think smok needs to fix the ss tc mode on the xcube 2. i set it to the tcr for 430 and i was getting nothing i had to up it to 160 for it to not just sit at temp protected the entire time. i even made another coil first thinking it was my build.

That is a good news. I kinda like(d) my SXM and happy to put it back to the rotation

ATM I use 316's 0.00085 as TCR for I have no rock solid data on 316L. (Cindas has no 316L, SE's 316L is more likely Cindas' 316) and adjust if my ambient temp guesstimation turns out being inaccurate

If I recall correctly I wound up raising the 316 TCR from your report of the CINDAS number by quite a lot, in relative terms, perhaps as high as 121 (guessing). Searching jazzvaper + "316" now...

No, what I said was that I preferred the linear TCR (0.00138, or 138 for 430) over the DNA 200 curve. Perhaps similar for 316. No clear memory, and a search does not show anything useful.

When cutting Unkamemen's NottyFe52 I don't use my good flush cutters, I use a previously abused pair.

Yeah, ruined my good pair before realizing it. Got some good replacements from Mouser.

 

[jazzvaper]

Memory returns:

Yes, it was 316 that I raised from 0.000915 to 0.00121 to get a good vape.

I'm glad to have left those low TCR's in the past. No reflection on those who must, to avoid Nickel, stay with SS.

understandable
the 316 is really pushing the limits especially higher gauges
My dual coil setting produces a 0.04 ohms resistance changes that makes it pretty difficult for the board

hardly any resistance change (purple) with massive power (green) and temp (red) fluctuation

Not the best vape that is for sure

 

[dwcraig1]

Just got done coiling my Aromamizer with NottyFe52, it's good.
Headed into EScribe Live View now.
Right now it's a noisy sucker, making full use of that anti-spit back drip tip. I't's getting better.

 

[GeorgeS]

I'm currently enjoying SS430 in all my adjustable TCR mods. Both my 350J mods have ~0.9 ohm slightly spaced single coils in TSV4's (with silica wick) and the Reliant is sporting a single contact 1.8ohm coil in a Lemo2 clone with cotton.

I patiently await a wire shipment from the EU.

I've transferred my Aromamizer to my Dicodes. Using in on a DNA200 with EScribe first to get an idea of things.
I have it set to TCR value of .0011, 110 in Dicodes speak.

Oh, I should mention that the DNA settings were my own that I did do a dry cotton burn test after but not water test.

He added it. On Steam Engine that is.
