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

[Trexwyo]

I thought dry burning Ti could cause TiO2.

I've been using Ti on a Sigelei 150TC in my aromamizer When it comes time to clean the coils I increase the temp setting from 335F Vape temp to around 475F cleaning temp. (Temp offset since the 150 Tc is Ni200 rated) Not even hot enough to see a glow the coils in room light and very dull barely red in full darkness. Plenty hot enough to cook off and gunk buildup. You don't need to worry about TiO2 unless you actually burn the coils to a Bright Glowing Orange like you would see dry burning Kanthal. Then if you read this link, Dry burning Kanthal at extremely high temps isn't good either. In this study the high temp is listed as 700 degrees C or almost 1300F Dry-burning metal coils: is it a good thing?

I'll compare the Samsungs to the Mxjo's when they arrive. Not too bad, a bit more sag than my Turnigy Lipo
Lipo sag:

18650 Mxjo 3000 mah 1865 x 3 sag:

I find it acceptable at the wattage that I will be using.
I truly believe they are 3000 mah as they took almost 8 hours to reach full charge in my I-4

I have come to understand that the reason for the extra battery sag with the 18650's might be because of the lighter gauge wire that they used to connect the battery sled to the board.

They seemed to have done a really great job with everything else, it doesn't make sense.

Shouldn't be too hard to swap them for better wires

Well what I get from that is that I would be doing better for my health by using Ti the way I do which is to wrap my Ti coil spaced place it wick it and vape it then clean it with hot water and a brush then rewick then it is to heat NiFe to glowing and compress it till it is glowing from the inside out changing the molecular structure of the metal and possibly making it easier to come off the coil and into my lungs through the vapor. So that would make Ti safer the way I do it then NiFe. Maybe I'm taking it all wrong but that is what I get from it which for me is something to think about when trying to decide which I like better which could be more important then the ease of use. As far as taste I find them both to be very good.

Here is the sag @ 100 watts with the Mxjo 3000 mah 18560's, pretty bad.

BTW, the pack voltage was 12.5 at the start.
Gee, I think I'm posting in the wrong thread.

That's about the way I was thinking also.

But there is another thing to think about, the inhalation of nickel unless it is in large quantities as in nickel mines is way less harmful to your lungs then the inhalation of nano particles of titanium even in small amounts.

I have a cure for your "sag". The ......, ......, and, Flomax of batteries: VTC 5's.

For me there is a Pack sag from 11.44 to 11.32 with a 50% charge at 50 watts, or, less than 10%.

I once had a B&M try to sell the MXJO's to me. Once we tracked down the specs he readily put those batts back under the counter, in the glass case.

The amount of dangerous misinformation proliferating on ECF is becoming a tragedy. We seem to be devoted to a climate of unjustifiable fear and respond with "solutions" which have the potential to be truly harmful. Please consult with those who have some scientific knowledge folks.

Right on bro! There is another thread here somewhere in the general forums with some dude preaching the word about how TC vaping is all a scam and that vaping VW with Ti is the way to go. Pages and pages of undiluted verbal jism, uninformed, dogmatic nonsense by and large. I didnt get involved. Just thought Id leave him to his ignorance...

Yeah I Googled Nickel inhalation and Titanium inhalation and these were from govt sources and you know they are always right.

 

[2legsshrt]

The only thing I was concerned about was what it does to nickel to dry burn it. The way I use Ti I doubt I get much of anything from it but still not sure about dry burning the nickel the NiFe sure works good though. The best thing about the NiFe is how easy it is to use the Ti takes a little more work but not that much and I never use it above about 420F but guys use it on mechs IDK about that.

 

[2legsshrt]

The only reason I was concerned was that I have COPD from you know what have to use Symbicort and have CT's twice a year and vaping has definately made things better so I didn't want to use something that would make it worse. I'm reasonably sure the way I use Ti it is safe but not sure about the way I use the NiFe. But even that I think the amount of nickel that is inhaled is still at a safe level. Probably not that much more then the air we breath especially if you live in a big city.

hey man. That was not directed at you, it was a general observation! Look, nobody can know for sure how good or bad these wires are, including kanthal. From my viewpoint, and having looked at it carefully, I think we are at worst, in a far better position than smoking! Ni is ok. The big deal with nickle is nickel carbonyl which is very hard to make even in a lab so thats not an issue. Ti is great as long as we dont make boat loads of flaky Ti O2, which, if we are even moderately careful, we wont. There is no problem as long as we take care to use these devices with just a bit of thought!
best

steve

edit: Ni sucks because it is just a rubbish TC wire! there are now better things to use, Ti being one of them! In my very humble opinion of course...

 

[jazzvaper]

I need to make a CORRECTION to my earlier post where I urged aTCR of 0.0045.

The later values (listed within that post) were actually for a TCR of 0.005 not 0.0045.

Today I modified that TCR to 0.0042. This latter number parallels the "rounding up" (from 40 to 41) that some Dicodes users have done.

I am now comfortable with a linear TCR of 0.0041 (41) or 0.0042 (42) for Nifethal 52 that hits and holds the Set Temperature. Arguably any fixed TCR greater than 0.00405 should have the same effect.

Sorry for any misunderstanding.

What? Unless it's oxidized why should Titanium be more harmful than Nickel, considering it's used daily in implants all over the world? Is this true or it's a joke I'm missing? Honest question, not trying to flame or anything.

@gorman - Truth is we don't know for sure any of the wires discussed are safe. We won't for years. People run around saying Titanium is inert & perfectly safe it must be they say, after-all it's used in implants. Shame on those ! Here's a good article with additional links. Read & judge for yourself.

Titanium | MELISA Medica Foundation

Nothing is ever simple!!! I tend to disregard any opinion that is framed in absolute terms. I.E. totally safe or it will kill you & everyone you've ever known if you try it even once

My on Tit. Short version:
I think from a material standpoint it is likely on the safer end of the spectrum, however the potential for operator error due to ignorance is on the dangerous end of the spectrum IMO. It's an easy mistake to make for inexperienced vaper to just pick up some Tit. in a nondescript package and then attempt to build just like A1 Kanthal, thus overheating the coils & forming Ti02 (titanium Dioxide) or building contact/micro coils instead of spaced and opening up the potential for arch's (vaporized metal) since there is no electrically insulative oxide layer. I'm leaving out a lot such as purity level, surface finish, chemicals/oils used in the drawing process, was it manufactured by a trustworthy source? Just in this thread over a few short months we've had 2 examples of total bogus alloys delivered from manufacturer's

I feel a rant coming. Maybe I can hold it back if there are no more builds at all, with the NotFeatall!

 

[cigatron]

Lots of peeps out there have more knowledge in the material sciences field than I ever care to know. All I think I know is that responsible vaping is way less harmful to my health than responsible smoking, if there's such a thing as either. I'm going on with my Kanthal, Ti, Nife and SS vaping until I quit or die, whichever comes first. That said, I trust more of what's being said about the health concerns of vaping by legit engineers in the public sector than the bs propaganda the gov agencies spew forth. We know what their agenda is.
End rant.

I hope you explore Titanium more thoroughly. I have spent my life developing titanium alloys for high temperature application in gas turbine engines and have over the years devoured virtually every word in the scientific literature relating to titanium and titanium dioxide.

I am unaware of a single case where titanium dioxide was associated with harm to a human being both in the processing industry for the raw metal or in facilities that produce titanium dioxide for consumer products such as paint, toothpaste etc. It's unfortunate that people who exposed themselves to true harm through long term smoking of tobacco do not have valid information or do not take the opportunity to find the information that is available about the relative dangers of materials used in smoking alternatives such as vaping.

Bye the way, human beings can be allergic to anything including their own body cells. My comments on titanium do not preclude human allergies but I an say that titanium is considered to be one of the least allergenic elements known.
