At present,the wire material used on the temperature control coils most are Ni200 nickel,some use the Titanium wire.
I saw some talks about the disadvantage and worries about Ni200 nickel material:
The Ni200 nickel can not handle the high current,it requires a little bit of "break-in" otherwise it tastes a little off at first.
Some people worry about the presence of nickel oxides formed through thermolysis may be inhaled and cause lung lesions.(Ni200 heated to 400 degrees Celsius which would be 720 something Fahrenheit in the presence of oxygen creates nickel oxide.)
There also some talks about the advantage and worries about Titanium wire:
Better flavor experience,It doesn't give metallic taste at all like ni200 does
It holds little residues,not like other wires do.
Large vapor production,because of greater surface coverage. (titanium has the half of nichrome resistance)
Even though, there are so many advantages of the titanium wire,but there are still some worries about the titanium dioxide.
Now,vapers are confused:what is a safe temperature control wire material i can use?
We also on the road to explore a safe temperature control wire material.
