Titanium and titanium alloys have good mechanical properties and mechanical properties, high specific strength, low density, nonmagnetic, high temperature resistance, small thermal expansion coefficient, good corrosion resistance and without brittle at low temperatures and a series of advantages, represented by TC4 titanium alloy is based on titanium to join other alloy elements. Titanium alloy with high temperature resistance, high corrosion resistance, high strength, low density, and biocompatibility etc, in the aerospace industry, chemical industry, nuclear industry, sports equipment and other fields has been widely used. Is also a modern aircraft and engine is one of the main structural material.

In the field of automobile, titanium and titanium alloy manufacturing can achieve fuel-efficient car parts, reduce the engine noise and improve the service life of the role.

Because the titanium and the human body has good biocompatibility and affinity, and light corrosion, odourless harmless etc, so it is widely used in pharmaceutical equipment, such as artificial joints, bone trauma fixed system.
