So got some titanium grade 1 wire from unmakensupplies at etsy.com as recommended at ecf.
Dont yet have a mod for Ti , so decided to test it out on the VS rDNA40.
A back of the envelop calculation said that if the tcr of Ni 200 is set at around 0.006 & Ti is 0.0035 ( just preliminary estimates as there are differences in what people say ), then to get 450F with TI , i should set the temp at 290F with Titanium.
So i made a coil - 3mm, 28awg Ti, around 8/9 wraps on my KF lite. Read 0.57 as expected. Did a slight burn at 8W - the wire turned alomst bluish
Anyway, wicked it & put in some milk & honey ( cosmic fog ).
And fired it up on the VS. At 290F, it was hitting TP too fast. So finally increased it to 350F and now its vaping nice
So there it is guys - Ti wire - u can use with ease on TP mods for Ni 200. Just start at 100-150F lower than you would use for Ni 200 and then slowly ramp it up as required
