# Thread: How to tell if something is titanium

1. ## How to tell if something is titanium

Does anyone know how to tell if a piece of equipment is titanium? I know it sounds crazy, but I bought a pair of titanium handrims 10+ years ago and am not sure if the handrims on my chair are those or aluminum ones I ended up with along the 10 year path of replacing rusting/old parts.

Anyone know of a good "is this really titanium" test?

Thanks!

2. Chainsaw. If the chainsaw gets destroyed, it's titanium. :-)

3. ## Better Than Nothing

4. This is the big give away - It should be a shiny dark silver. Also with Ti handrims you don't get black hands like you do the Alu ones.

Post a good pic of them and i will tell you.

6. If you can be sure that you can eliminate any air pockets do this:

Weigh them, then submerge in water of a known volume. Measure the increase in volume. That is the volume of metal. Ti is 4507 kilograms per cubic meter, or 4.507 grams per cubic centimeter. 1 cubic centimeter is equal to a milliliter.

Anyone wanna check my math?

I like the scientific approach. Are titanium products pure or or some sort of alloy usually? Just curious.

what if it's a titanium duck? or a witch?

10. I guess the most simple way to tell would be to take a magnet to the rims. If they are steel they will pull the magnet right toward them, if they are Titanium they will only very slightly draw the magnet towards them (if at all depending on the grade of Titanium) since Titanium is "Paramagnetic" http://wiki.answers.com/Q/Is_titanium_magnetic
