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

[GeorgeS]

Heck since the SS430 has a higher TCR of 138, I'm not sure why bother messing with wire that has an even lower TCR? I do want to do one test coil to confirm Jimscotty's results.

Until the realtheal arrives from the EU I guess I'll stick with SS430.

Indeed, Ralph attempted to do US a good turn. I reminded him that "we" appreciated his effort.

And, that those of us in the States would like to have a US Vendor option. He commented that he was sending what he received out for testing (possibly for a claim against his wrongful supplier?).

The point, as GeorgeS intimates, is to move on. My 24 awg from Zivipf is due for delivery tomorrow. Looking FORWARD to that.

Is it possible it is Invar? 36% Ni rest iron.. Can't find a tcr for it....

Also known generically as FeNi36. Could be. Or maybe one of these with Ti added:

Iron-Nickel-Chromium Alloys. This series of alloys has also found extensive use in the high-temperature petrochemical environments, where sulfur-containing feedstocks (naphtha and heavy oils) are cracked into component distillate parts. Not only were they resistant to chloride-ion stress-corrosion cracking, but they also offered resistance to polythionic acid cracking. Some alloys of commercial importance include:

• Alloy 800 (Fe-32Ni-21Cr). The basic alloy in the Fe-Ni-Cr system; resistant to oxidation and carburization at elevated temperatures
• Alloy 800HT. Similar to 800H with further modification to combined titanium and aluminum levels (0.85 to 1.2%) to ensure optimum high-temperature properties
• Alloy 801. Increased titanium content (0.75 to 1.5%); exceptional resistance to polythionic acid cracking
• Alloy 802. High-carbon version (0.2 to 0.5%) for improved strength at high temperatures
• Alloy 825 (Fe-42Ni-21.5Cr-2Cu). Stabilized with titanium addition (0.6 to 1.2%). Also contains molybdenum (3%) for pitting resistance in aqueous corrosion applications. Copper content bestows resistance to sulfuric acid
• Alloy 925. Addition of titanium and aluminum to 825 composition for strengthening through age hardening

Maybe Nikrothal 20 which is an austenitic nickel-chromium alloy. This is out of my area of expertise but maybe one of our metallurgists, ie. @druckle, can step in to straighten us out.

If u can't find a local person u can send them to me to install for u.

Cool. If this starts looking like we don't have a chance I may order a couple SXM's and a couple 350-J boards so I am covered in that dept. Ordered 1 liter of nic 100mg everyone has it on sale, mine was a little more then others at $50 but it is premixed to 50/50 I would hate to go back to whatever was around in 2006. Still haven't figured out what there was then maybe a 6v lantern battery and a possible atomizer not sure if they were even out then.

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

Well that is a pretty damn close TSR to what I found at .00114 and I could have called it at .00117 because it gave the same readings.

I forgot to mention that the wire is also attracted to a magnet.

No TC wire here just my first DIY clapton, 26 gauge Kanthal ane 32 gauge Nichrome. I think if I get set up good I can get it right. This has the small wire wraps are too far apart. I did get on to it but only towards the end.

I've taken a dozen pics of the coil, I can't seem to get better than this one??? It does vape pretty well.

Edit: BYW, for you folks that are thinking about making some well it's pretty easy....once you get the hang of it.

You will be onto the Staple Staggered Fused Clapton before too long...

 

[TrollDragon]

Or even the Clapton wrapped with a Clapton...

Not my builds, well above my skill set...

 

[dwcraig1]

Not even wanting to build clapton coils with Ti so I ordered 164 ft of NiFe48 from zivipf.
Edit: So after thinking about using Ti for the core maybe it wouldn't be all that bad, any oxidation would be contained by the outer wrapped wire.I still don't feel good about using it in this application. I sure do like using Ti for regular coils though.

 

[WharfRat1976]

Got my 317L from Unk. Any build suggestions or just wrap mount and vape?
Will 317L respond to TC?

 

[BrentMydland]

Just wondering, did anyone ever find a good source for SS410?

Yes, absolutely.

I have ordered a spool from a Chinese factory. I have received it today but I don't have enough time to test it, maybe tomorrow. This wire seems to be VERY dirty.

My sense is that NiFe48 will be my mainstay wire.

Have done 430, which I liked; but for the sake of science (higher TCR) I should try 410.

Please provide a link.

Unfortunately the MOQ is 1 kilogram. I have received 0.5kg (0.3mm) as a sample.
The Nifethal52 is a very good wire, it has a lot of advantages.
My personal choice is Ti because we know every important thing about it, thank to @druckle. But I like to play with these new materials, who knows.

I just got some NiFe 52 (Renamed NiFe 48 by Zivipf) and wrapped a 24 gauge 0.21 ohm very slightly spaced coil on a 3mm mandrel which is the standard Ti coil I use most times.

The resistance of the NiFe52 is lower than Grade 1 Titanium so it took 9 wraps rather than the 7 required for Titanium to get the 0.21 ohm resistance resistance for direct comparison with Ti. That was a problem with the small chamber Manta dripper I used for evaluation because with the coil placed directly in front of the air slots the coil shorted on the top cap. I moved the coil and all was well again as far as resistance. I used the NiFe 52 .csv file from Steam Engine for TCR control in a DNA 200 device.

The materials works. but so far I see no particular benefit over Titanium. The flavor seems muted compared to Titanium but that could be several things. The most likely might be the lower power density as a result of the somewhat longer NiFE 52 coil. Of course it could be some detail about the wicking although I used the same quantity of wicking material and the coil diameter was equivalent for NiFe 52 and Titanium or it could be that the less precise placement of the air slots on the coil caused the flavor reduction.

I'm going to explore more thoroughly but so far I don't see any benefit to the new material and there is a downside for me in the lower resistance.
