Titanium vs Stainless vs Titanium-Coated: What's Actually Pure?
You're shopping for a camping cup and half the listings say "titanium." But one costs $25 and another $170. They can't all be the same thing — and they're not. Here's how to tell what's actually pure, and why it matters more than the label suggests.
Three materials that all get called "titanium"
- Pure (commercially pure) titanium — Grades 1 to 4, no coating, no other metal underneath. This is the real thing.
- Stainless steel — sometimes sold alongside titanium, or finished in a "titanium colour." Strong and cheap, but heavier, and it can taste metallic.
- Titanium-coated — a thin layer of titanium deposited (PVD) over a steel or aluminium base. Looks like titanium, but once the coating wears you're drinking from the base metal.
The weight test
Stainless steel weighs roughly 7.9 g/cm³. Pure titanium weighs about 4.5 g/cm³ — around 43% lighter for the same wall thickness. On a multi-day trip, that's the difference between noticing your cup and forgetting it's there. If a "titanium" cup feels as heavy as a steel one of the same size, it's probably not pure.
The taste test
Stainless can give hot or acidic drinks — coffee, citrus tea — a faint metallic edge. Pure titanium is chemically inert and biocompatible (it's used in medical implants for exactly that reason), so it contributes no taste at all. A coated cup tastes fine until the coating scratches; then the base metal shows through.
The durability test
Pure titanium can dent if you really throw it at a rock, but it won't corrode, won't flake, and won't develop a taste over time. Coated drinkware's weak point is the coating: every scratch exposes the cheaper metal underneath, and over years the finish simply wears off. Pure titanium has nothing to wear off.
How to verify you're getting pure titanium
- Look for the grade — "Grade-1," "Grade-2," or "commercially pure."
- Check the weight against a steel equivalent. Lighter = a good sign.
- Look for an explicit "uncoated" or "pure" claim, not just "titanium colour."
- Price is a signal: pure titanium costs more because the raw material costs more. A suspiciously cheap "titanium" cup usually isn't.
Rule of thumb: if a seller won't state the grade, it probably isn't pure. Honest pure-titanium brands lead with the grade.
