What is Titanium?

Titanium is a chemical element with the symbol Ti and atomic number 22.

Ten characteristics of titanium:

(1) Low density, high strength and high specific strength
The density of titanium is 4.51g/cm3, which is 57% of that of steel. Titanium is less than twice as heavy as aluminum and three times as strong as aluminum.
(2) Excellent corrosion resistance
The passivation of titanium depends on the presence of an oxide film, and its corrosion resistance in an oxidizing medium is much better than that in a reducing medium.

(3) Good heat resistance
Usually aluminum loses its original properties at 150°C, stainless steel loses its original properties at 310°C, and titanium alloys still maintain good mechanical properties at around 500°C. When the speed of the aircraft reaches 2.7 times the speed of sound, the surface temperature of the aircraft structure reaches 230 ℃, aluminum alloy and magnesium alloy can no longer be used, and titanium alloy can meet the requirements. Titanium has good heat resistance and is used in the disks and blades of aero-engine compressors and the skin of the rear fuselage of aircraft.
(4) Good low temperature performance
It can be used on dry liquid hydrogen and liquid oxygen rocket engines, or as ultra-low temperature containers and storage tanks on manned spacecraft.
(5) Non-magnetic
Titanium is non-magnetic, it is used in submarine hulls and will not cause the explosion of mines.
(6) Small thermal conductivity
The thermal conductivity of titanium is small, only 1/5 of steel, 1/13 of aluminum, and 1/25 of copper. Poor thermal conductivity is a disadvantage of titanium, but this feature of titanium can be exploited in certain applications.
(7) Low elastic modulus
The elastic modulus of titanium is only 55% of that of steel, which is a disadvantage when used as a structural material.
(8) Tensile strength is very close to yield strength
The tensile strength of Ti-6AI-4V titanium alloy is 960MPa and the yield strength is 892MPa, the difference between the two is only 58MPa
(9) Titanium is easily oxidized at high temperature
Titanium has a strong binding force with hydrogen and oxygen, and attention should be paid to preventing oxidation and hydrogen absorption. Titanium welding should be carried out under argon protection to prevent contamination. Titanium tubes and sheets should be heat treated under vacuum, and a micro-oxidizing atmosphere should be controlled during heat treatment of titanium forgings.
(10) Low anti-damping performance
The bells are made of titanium and other metal materials (copper, steel) with the exact same shape and size. If you strike each bell with the same force, you will find that the bell made of titanium oscillates for a long time, that is, through The energy given to the bell is not easily dissipated by the striking, so we say that the damping performance of titanium is low.

Ten Applications of Titanium:

(1).Pigments, additives, and coatings
Used in paints, paper, toothpaste, and plastics. It is also used in cement, in gemstones, as an optical opacifier in paper, and a strengthening agent in graphite composite fishing rods and golf clubs.
Used in aircraft, armor plating, naval ships, spacecraft, and missiles
Used to make propeller shafts, rigging, and heat exchangers in desalination plants;heater-chillers for salt water aquariums, fishing line and leader, and divers’ knives.
Welded titanium pipe and process equipment (heat exchangers, tanks, process vessels, valves) are used in the chemical and petrochemical industries primarily for corrosion resistance.
Titanium metal is used in automotive applications, automobile, motorcycle racing and bicycle frames and components.
(6).SportingTennis rackets, golf clubs, lacrosse stick shafts; cricket, hockey, lacrosse, and football helmet grills,
(6).Spectacle frames
Titanium alloys are used in spectacle frames that are rather expensive but highly durable, long lasting, light weight, and cause no skin allergies.

Many backpackers use titanium equipment, including cookware, eating utensils, lanterns, and

tent stakes.
Titanium rings, Some artists work with titanium to produce sculptures, decorative objects and furniture.

Surgical implements and implants, hip balls and sockets (joint replacement) and dental implants, surgical instruments used in image-guided surgery, as well as wheelchairs, crutches.

(10).Nuclear waste storage
Titanium containers have been studied for the long-term storage of nuclear waste.
