Joint Replacement Parts
Titanium is used in joint replacements because it is just as strong as steel and much lighter than it too. It resists corrosion and can last up to 20+ years in a joint.
Dental Implants
Titanium is used in dental implants because it is able to "osseointegrate" (an unusual ability by which titanium fuses with bone tissue, through the titanium oxide layer on tianium metal).
Money Clips
Titanium is extremely elastic (springy), lightweight, corrosion resistant and non-magnetic and this results in new uses such as for money clips used to hold bank notes and even credit cards (as titanium is non-magnetic it has no effect upon the card's magnetic strip).
