I don't have any specific experience with wearing Titanium Jewelry through airport security, ..but Titanium is non-ferrous, and has an extremely low magnetic field. ..so low in fact that it is widely considered to be non-magnetic. I doubt titanium would set off a metal detector, but I wouldn't rule out that it might be detectable by more advanced scanners. Hopefully other members here might be able to answer your question with real world experiences, ..Because I would like to know the answer to this as well.
Titanium will not set off a typical metal detector... but they will show up quite clearly in the back scatter detectors. As will a plastic device, BTW. Just take the damn thing off before your flight and put it on after you get there. This is how Mrs Edge and I deal with it; she certainly trusts that I'm not going to have a wank in an airport bathroom.
She's very trusting and you're very trustworthy. I put mine back on in the airport bathroom and dont wait until after I get there, because I'm a repeat member of the mile-high masturbator club.
I could easily go without until we get where we are going. It's more about the excitement of staying locked public for me.
Opt out of the backscatter imaging booth, and ask for a pat down. I’ve done that. Not a big deal. I think you’ll be fine nowadays.
Note that ferromagnetism is not an absolute requirement for detecting electrically conductive materials. That having been said, the electrical conductivity of titanium is not that great.
Metal detectors work from eddy currents. Thus they can detect non ferrous metals. Eddy currents are induced electrical currents that in turn create magnetic field lines in any electrical conductive material that passes through a different magnetic field. The metal detector is a magnetic field with sensors that pick up fluctuations in the magnetic field. These fluctuations are from the eddy current produced magnetic field lines in the subject material.
