Coil Science: Why the Metal in Your Vape Matters for What You Inhale
Vape coils are made of kanthal, nichrome, stainless steel, or titanium. Each metal has different heating properties—and different potential for releasing metal particles into the aerosol. Coil science is a neglected dimension of vaping safety.
Kanthal (iron-chromium-aluminum) is the most common coil material—stable, inexpensive, and widely used. Nichrome (nickel-chromium) heats faster but may release trace nickel. Stainless steel can be used in temperature control mode. Titanium is controversial—potential for toxic oxide formation at high temperatures. **The metal in your coil affects what you inhale. Coil science is understudied, underregulated, and almost never discussed with consumers. The coil is not a neutral component. It's a safety variable.**
