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

[f1vefour]

Just have not had the time to try it. 12hr work days and cutting firewood every morning.....I'm spent brother and I won't get a break until this weekend.

No worries at all, take care of business. I know exactly how you feel less the firewood. I know what it's like to cut wood just not since moving to Florida.

Is there any news or updates on Theblokes whereabouts? The nobel founder of this wonderful list.

no news for a while. Hope all ok with him and family!

Did the SS430 work on the VT in Ti mode?

Update: Twisted up the 430ss, heated it with a torch to dull red, installed a 6 wrap slightly spaced on my STmini. Initial res was .37 on my Evic. Coil fired perfect on first pulse in power mode. I ran it up to yellow a couple of times to heat harden it. Wicked it heavy with kgd, same as my previous twisted kanthal builds.Hopefully it will refine down to .34 or .35 because my temp setting has to be down around 210°f to keep the vapor cool enough to vape. I'll let it sit overnight to see. More later.

Special thanks to @f1vefour and @Landman for your 430ss contributions.

Great threads are made of great peeps!

Hopefully it will cigatron, it's so hot @ 210 it will likely burn the wick?

Not that hot. Just hotter than I like. At 210 it seems to produce about 50°f hotter vapor than I like. If it only refines by minus .01 ohms it may be fine at 200-210°f. Something that can be safely said is that unless your non-adjustable tcr mod severely underheats in ti mode, as the evic does, you will not be able to run 430ss.


Update: Res has refined to .36 already. Temp set to 230. Better. Performance wise, the Evic's temp setting is very sensitive eg. 220 is too cool and 230 is almost too hot. Also the Evic is not regulating power quite as smoothly as with Ti.

Looks like I may have to use titanium on the cloupor then. That sucks.

Check update.

There's an update? Where?

Update to my post. Sorry, didn't mean to get your hopes up.... lol

Check update.

Well I guess we just have to use what works best for the device we have, looks like it's titanium for the VT unfortunately.

It's usable for you but not much so?

Time will tell. Brand new cotton wicks can act funny sometimes. Could be irregular juice transport during vaping that's causing temp fluctuations. I'll know more tomorrow once the wick breaks in.

Nife52 is still an option I would LOVE to try but if all I can reliably use is Ti I will be happy. Dryburning Ti at 7w is working perfect to clean things up. The 24g Ti coils are tough/rigid, gunk less with nets because of its extremely fast cool down time and the flavor is great.

 

[f1vefour]

My largest issue with Ti is I like to dry burn the shiat out of my coils and I like switching to wattage only and mechs.

I got over the need to see blinding light to clean my coils...lol. Just pulsing to dull red, a few strokes with an old wet toothbrush and a quick rinse brings Ti coils to like new condition.

I'm with you on cross device use though. I used to use like 6 different gauges of kanthal; a different gauge for almost every atty I had back in the days of battery limitations. Now it's 24g Ti for tc and 24g kanthal for my drippers. Not so bad to deal with only two wires.

 

[f1vefour]

It's not the wires that I have issue with, I need the ability to go from TC to a mech with the same build. I don't have a bunch of atties in rotation, I like to keep it simple as possible. Currently I use a Zephyrus, a Kayfun, and an Atomic dripper.

I don't get my coils blinding hot because I'm wary of melting insulators, but still much hotter than Ti allows.

Reposting this from the VTC thread:

I'm running SS430 on my VTC Mini
Ti mode at 220F and 30W - resistance locked at 0.15
2 strand twisted 28g dual coil on a TOBH rda

It's weird - when I first built it, the mini would bump out of TC mode immediately.
Fast forward a couple hours and now it's staying in TC and giving a very consistent vape.
It's to be noted that the resistance originally read 0.18 when bumping out of TC, but now reads 0.15 when holding in TC. Now the mod's holding solid at 0.15.
At 220F it's a cooler vape (which I prefer) but still with a lot of cloud and flavor production. I pretty sure there's more headroom in the temp setting, but like it where's it's at.

I'm really enjoying the clean flavor from the 430 - to me, the best out of Kanthal, Ni, and Ti. It's a PITA to work with though - very springy - twisting the wire in my drill almost had me kicking puppies. I keep coils for months though with cleaning and re-wicking, so worth the aggravation, imho.

Got a couple of Bellus tanks coming - can't wait to try out similiar build in them.

Is there a calculator for SS 430?

 

[2legsshrt]

Could the TCR of a type of wire be different at room temp then at vaping temp? Just wondering why the TCR's listed on Wire Wizard are different then what was put out in the list.

There's an app for iPhone called Coil Genius that lets you define your own wire types.

Yes. With a TCR, the "real" temp/resistance curve is approximated by a straight line. It is a good idea to choose the line in such a way that it crosses the curve near the temperature range used for vaping. E.g. the "TCR for 200ºC" corresponds to a line crossing the curve at 20ºC and 200ºC. Near these points, this approximation is good. In between (e.g. at 100ºC), it may be not that good.

 

[2legsshrt]

Makes sense. Maybe that is the reason the TCR values on Wire Wizard at vaping temp is different from what was in the list for example Ti on list was .00350 and Wire Wizard it is .00366 in vaping range.
