.15 Ohm, Highly interchangeable across numerous subtank platforms including Aspire, Vapeston, Maganus, Freemax, Starre, Anyvape, Sega Sub Tank, Eleaf Melo, Sense Tech, Tobeeco, and Herakles. These marvelous sub-ohm atomizer heads use nickel wire rather than the Kanthal resistance used in standard Atlantis coils. Nickel alloy Ni-200 has many unique and useful properties, such as magnetic and magnetostrictive properties, high thermal and electrical conductivities, low gas content, and low vapor pressure. These characteristics provide for longer-lasting coils, larger vapor clouds, and better overall hits. Designed for use in temperature sensing devices.
