Does Titanium Rust?

Q: My hands are super sweaty and my saddles are always rusting and smelly. Does titanium rust? My friends won't even play my guitar because the bridge looks so nasty. Will your saddles help?

A: Titanium is well known for its excellent corrosion resistance (almost as resistant as platinum), being able to withstand attack by acids, moist chlorine gas, and obviously hand sweat. It is a light, strong metal with low density (60% as dense as steel) that, when pure, is quite ductile (especially in an oxygen-free environment), easy to work, lustrous, and metallic-white in color. Titanium is as strong as steel, but 43% lighter; it is 60% heavier than aluminum, but twice as strong; however these numbers can vary a little because of the use of different alloys. These properties make titanium very resistant to the usual kinds of metal fatigue and hand sweat.
