Titanium Wire – What is it in Vaping?

Definition

Titanium Wire is a high-grade metal heating element used in rebuildable atomisers and temperature control (TC)vape devices. Made from pure or alloyed titanium (most commonly Grade 1), this thin, springy wire coils inside an RDA, RTA or tank to vaporise e-liquid when heated. Its main purpose is to give vapers a cleaner flavour, faster ramp-up and—crucially—accurate temperature control that prevents dry hits and burnt cotton. Beginners often meet titanium wire when they move from stock coils to DIY builds, while advanced Australian vapers prize it for its light weight, high resistance stability and consistent performance under the country’s TPD-compliant nicotine laws.

Technical Details

Titanium wire operates by increasing its resistance in a predictable, linear way as temperature rises. A TC-enabled chipset measures this change (≈0.0035–0.0039 Ω/°C for Grade 1 Ti) and limits power to keep the coil at the set °C/°F. Typical diameters are 22–28 AWG (0.32–0.64 mm); resistance is roughly 0.35 Ω per inch for 24 AWG, so builders target 0.05–0.50 Ω depending on single or dual-coil configuration. Popular variations include:

• Grade 1 (purest, easiest to work)
• Grade 2 (slightly stronger, marginally higher resistance)
• Ti-6Al-4V alloy (rare in vaping—avoid unless specified TC-Ti setting)

Surface finish can be bright (polished) or “black” (heat-oxidised); the latter helps prevent loose titanium particles and improves wicking.

Usage & Tips

Before first use, “dry-fire” titanium wire at 10–15 W in a dark room until it glows dull orange, then quench with ceramic tweezers to remove machining oils and create a stable oxide layer. Always use a dedicated TC-Ti mode; never fire in wattage-only mode, as overheating can release titanium dioxide—unpleasant for Hit“>throat hit and potentially unsafe. Space your coils slightly to avoid hot-spots and wick loosely with high-quality cotton for consistent saturation. If resistance jumps erratically, check 510 connections and ensure the build is room-temperature when the mod is locked. When travelling, store spare wire in a sealed bag to prevent contamination—especially important under Australia’s humid climate.

History & Context

Titanium entered the vaping scene around 2014–2015 as DNA40 and early Yihi chips introduced reliable TC. Australian enthusiasts adopted Ti wire after nickel (Ni200) proved too soft and flavour-tainting, making titanium the preferred middle ground between safety, performance and ease of building in both top-fillsub-ohm tanks and drippers.
