It is said Titanium Dioxide is hazardous if inhaled - but Ti Dioxide does not begin to forum until 1200°F (600°C), so well beyond safe vape temperatures. That said it should not be dry burned for that very reason. Good news is, Ti
coils tend not to gunk up as quickly as other
coils. The
coils should be spaced to eliminate hot spots and to avoid the dry burn method for performing such action.
It is more springy than say Kanthal, but I did not find 24awg to be problematic, and was easily able to make a spaced coil using a 3mm jig.
It is lower in resistance than SS316L, but still higher than Ni200
Titanium has a higher Specific Heat Capacity than the usual wire we use, but a much lower mass. Its mass means less power is needed to mitigate rampup time.
Titanium has a relatively high Temperature Coefficiency of Resistance, 0.00366 as per Steam Engine, therefore it is best used in Temperature Control.
I did not notice anything special using Ti, 24awg 3mm, 6 to 7 wraps vs a similar build of another metal outside needing less wattage.
