Guessing you want 40g Ni80 for wrapping claptons?
Titanium is for TC but make sure you read up on the wire & it's potential health risk from titanium dioxide TiO2 that can form when titanium is heated beyond a certain point. Definitely no dry burning.
If you're after Brochrome (flat Ni80) go to Stealthvape. They have Ni80 up to 38g/500m at £19.99.
