You do understand it’s a resistive heating element just like an electric baseboard heater or space heater? There’s no “metal atoms boiling off”, a typical alloy used for vape coils is Kanthal, which is iron/chromium/nickel which melts at 2,500F

You are not heating up the atomizer anywhere near that temperature with (2) 18650 cells. Coils are replaced when the cotton that surrounds them gets dirty and the vapor starts tasting bad.
