The minerals of titanium distribute widely in the nature. The main minerals are including: TeTiO3, TiO2,and vinado-titano-magnetite. The percentage of the titanium is 0.64% in the earth. It’s behind Al, Fe and M. The Ti resource of China is the 1st in the world.
The titanium alloy has high intension, especiallyTi-6Al-4V. Titanium, which weighs forty percent less than carbon steels, can be strengthened by alloying it with elements such as aluminum and vanadium. Titanium is nonmagnetic and possesses good heat transfer properties. It has the ability to passivate, thereby giving it a corrosion resistance to acids. It is also nontoxic and biocompatible. These properties make titanium and its alloys useful in a wide range of structural, chemical, petrochemical, marine and biomaterial applications.

2.     Wide application of titanium

Titanium and its alloys are useful in a wide range of structural, chemical, petrochemical, marine and biomaterial applications.

Titanium also is valued in the petrochemical industry, where it is used in heat exchangers and reactors. The automotive industry uses it in automotive components including connecting rods, valves, and suspension springs. The sporting goods industry uses the metal in the manufacture of bicycles, golf clubs, tennis rackets, and wheelchairs designed for disabled people who want to participate in a sport.

Titanium is used in condensers and turbine blades in electric power plants. It is also incorporated into the architecture of buildings, roofs, piping and cable.

Because of its corrosion resistance, titanium and its alloys are used extensively in prosthetic devices such as artificial heart pumps, Titanium heart pacemaker cases, heart-valve parts and load bearing bone or hip-joint replacements or bone splints. Human body fluids are essentially chloride brines with pH values ranging from 7.4 into the acidic range and also contain a variety of organic acids and other media, to which titanium is totally immune.

Other common applications of titanium include shape memory eyeglass frames, watches and jewelry.
