Due to their high tensile strength to density ratio, high corrosion resistance, and ability to withstand moderately high temperatures, titanium alloys are used in aircraft, armor plating, naval ships, spacecraft, and missiles. In fact,about two thirds of all titanium metal produced is used in aircraft engines and frames, such as rotors, compressor blades, hydraulic system components and nacelles.
The corrosion resistance and high temperature properties of titanium and its alloys makes this metal a prime consideration for use in marine environments.In oil and gas drilling as well as sea water applications, the corrosion problem is serious, and titanium substitution will permit less frequent replacement of corroding underground shafts.
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 instruments used in image-guided surgery, as well as wheelchairs, crutches, and any other products where high strength and low weight are desirable.
Titanium are used in automotive applications, particularly in automobile or motorcycle racing, where weight reduction is critical while maintaining high strength and rigidity. Titanium is used in many sporting goods:tennis rackets, golf clubs,lacrosse stick shafts, cricket, hockey, lacrosse and football helmet grills, and bicycle frames and components. Titanium alloys are also used in spectacle frames. The two most common titanium alloys used in the cycling industry are 6AL-4V (Grade 5）and 3AL-2.5V(Grade 9). These two different alloys are both high strength titanium and are both fairly common in the industry.
In the chemical industry the corrosion resistance of a metal plays the most important part. However,light weight and strength are desirable.Production equipment which facilitates transportation of corrosive materials such as acid, alkali, and inorganic salts are logical applications for titanium. Manufacturing equipment such as vats, reflux towers, filters, and pressure vessels give additional opportunities for the utilization of titanium. Titanium tube improve the performance of heating coils in laboratory autoclaves and heat exchangers.
Most industries employ fasteners in some form or other,and titanium is also now found in a wide variety of consumer products such as jewellery industry.
