    Titanium is a strong and lightweight refractory metal. Alloys of titanium are critical to the aerospace industry , due to their numerous unique properties, are also used in medical,aerospace, chemical and military applications, as well as in sporting goods.The passage mainly introduces the application of titanium in aerospace and medical field.

       Titanium – Aerospace application

    Titanium is used in engine applications such as rotors, compressor blades, hydraulic system components and nacelles. Titanium 6AL-4V alloy accounts for almost 50% of all alloys used in aircraft applications.

    Due to their high tensile strength to density ratio, high corrosion resistance, and ability to withstand moderately high temperatures without creeping, titanium alloys are used in aircraft, armor plating, naval ships, spacecraft, and missiles. For these applications titanium alloyed with aluminium, vanadium, and other elements is used for a variety of components including critical structural parts, fire walls, landing gear, exhaust ducts (helicopters), and hydraulic systems. In fact, about two thirds of all titanium metal produced is used in aircraft engines and frames.

       Titanium – Medical application

     Because it is bio-compatible (non-toxic and is not rejected by the body), Titanium is used in different medical applications including surgical implements and implants, such as hip balls and sockets (joint replacement) that can stay in place for up to 20 years.  Titanium has the inherent property to osseointegrate, enabling use in dental implants that can remain in place for over 30 years.  This property is also useful for orthopedic implant applications.  Titanium is also used for the surgical instruments used in image-guided surgery, as well as wheelchairs, crutches, and any other products where high strength and low weight are desirable. The unique qualities of titanium also prove to be MRI (Magnetic Resonance Imaging) and CT (Computed Tomography) compatible.
