Titanium wire is still relatively new on the market and is used in many sub-ohm tank coil heads for Temperature Control. It is considerably stronger than Ni200, making it much easier to work with. The resistance of Titanium is about double that of Ni200, allowing you to use considerably less wraps compared to Nickel when reaching your target resistance. A concern worth noting for Titanium is the fact that it can heat up to a point of ignition. If the metal combusts, you will see a flame that no fire extinguisher can put out; in which case you just have to let it burn out. Also worth noting is the formation of Titanium Dioxide which can be harmful to your health if inhaled. The good news is that Titanium Dioxide only forms in temperatures around 1,200°F (600°C). This may seem like a lot, just remember that a brightly glowing orange coil can easily exceed temperatures up to 1,300°F. A simple solution is to not glow your coils and you’ll never have to worry about combustion or Titanium Dioxide. If you see any kind of white powder forming around your coil, please be sure to dispose of the wire and wrap a new coil. Titanium Dioxide is no joke and can produce some serious side-effects if ingested for an extended period of time. If you are unsure or have any doubt about your coil, simply throw it away and start a new.
