Titanium's unique combination of attributes - light weight, high strength, biocompatibility, and durability in extreme environments - make it an excellent material for a variety of non-traditional applications.
Titanium is completely inert to human body fluids, making it ideal for medical replacement structures such as hip and knee implants. Titanium actually allows bone growth to adhere to the implants, so they last longer than those made of other materials. Reconstructive titanium plates and mesh that support broken bones are also commonly used today.
High strength-to-weight ratio and superior ballistic properties make titanium well suited for armor applications. Used as protective armor on personnel carriers and tanks, it makes the vehicles much lighter, increasing mobility of the force. Personal armor vests and helmets for police made from titanium are far lighter and more comfortable than those made from competing materials.
Titanium is also now found in a wide variety of consumer products such as jewelry, watch cases, eyeglasses, bicycles and clocks.
The golf industry has found that lightweight titanium club heads can be bigger than those made of steel, enlarging the "sweet spot" of the club and thus increasing distance and accuracy.
