Will post this here too. This is an email I got from Sweet Spot as to why their wire is supposedly the best there is for vaping. T or F what do you think.
Hi Pat,
The production conforms to ASTM F67. Our test methodology conforms to ISO5832. Our billets start life as certified gr2 medical grade Ti, and then move into our proprietary vacuum annealing process, to remove o2 impurities in the material substrate. I would like to think we are producing the ONLY vape specific Ti on earth, and are sourcing the purest raw Ti possible. We also ultra sonic/stem clean ALL wire in our own facility. ALL re-spooling, cleaning, packing and QC is done in our facility in California.
Our trace elements are below 0.3%.....and our o2 content is below that of GR1 Ti. Gr1 Ti is not ideal, because it lacks other critical trace H, N and C (hydrogen, nitrogen and carbon) as well as Fe (iron) to properly insulate against premature oxidation. Our total iron content is 0.08%....low enough to avoid iron oxide, but high enough to be durable enough for use on a mech.
Hope that answers some questions.
P.S. our wire finish is shiny/clean….but not polished….we avoid polishing as we don’t want the heat from polishing to infuse any surface contamination. On the issue of cost our wire is actually lower in price (per foot) than the industrial Gr1 Ti sold on amazon…..the amazon wire is uncleaned and wholly inadequate for vaping. Spider Silk is just regular off the shelf gr1 Ti. You will also notice quite a few benefits over Ni wire. Number one no NiO2, cleaner taste (no taste actually) greater durability etc etc….
