Titanium has great strength, and the tensile strength of pure titanium is up to 180kg/mm2. Some steels are stronger than titanium alloys, but the specific strength (the ratio of tensile strength to density) of titanium alloys exceeds that of premium steels. Titanium alloy has good heat resistance strength, low temperature toughness and fracture toughness, so it is mostly used as aircraft engine parts and rocket, missile structural parts. Titanium alloys can also be used as fuel and oxidizer tanks and high pressure vessels. Titanium has been used to make automatic rifles, mortar mounts and recoilless gun tubes. In the petroleum industry, it is mainly used for various containers, reactors, heat exchangers, distillation towers, pipelines, pumps and valves. Titanium is used for electrodes and condensers in power stations and for environmental pollution control devices. Ti - Ni shape memory alloys have been widely used in instruments. In medicine, titanium can be used as artificial bones and utensils. Titanium is also a deoxidizer for steelmaking and a component of stainless steel and alloy steel. Titanium dioxide is a good raw material for pigments and paints. Titanium carbide, carbon (hydrogen) titanium is a new hard alloy material. Titanium nitride is similar in color to gold and widely used in decoration.
Titanium and titanium alloys are widely used in the aviation industry, known as "space metal"; In addition, in shipbuilding industry, chemical industry, manufacturing machinery parts, telecommunications equipment, cemented carbide and other aspects have been increasingly widely used.
