Where is the titanium metal used in high-tech fields?

In daily life, we often hear that titanium is used in certain high-precision fields. So what kind of tall metal is titanium? What is unique about it so that it is favored by top products? Today, Baoji Kayite New Materials will give you a popular science, where is the titanium metal used in the high-tech field?

Titanium is a chemical element

First of all, titanium is a chemical element. Titanium was discovered by British chemist Gregor while studying ilmenite and rutile in 1791. Four years later, in 1795, the German chemist Klaprott also discovered this element when analyzing red rutile produced in Hungary. He advocated adopting the method of naming uranium (discovered by Klaprott in 1789), citing the name of the Titanic tribe in Greek mythology, “Titanic”, and naming this new element “Titanium”. The Chinese name is named Titanium according to its transliteration.

Titanium is also a metal

Secondly, titanium is also a metal. Titanium looks like steel, with silver-gray luster. The titanium discovered by Gregor and Kraprot at the time was powdered titanium dioxide, not metallic titanium. Because the oxide of titanium is extremely stable, and metal titanium can be directly and fiercely combined with oxygen, nitrogen, hydrogen, carbon, etc., elemental titanium is difficult to prepare. It was not until 1910 that the American chemist Hunter made the purity for the first time. Up to 99.9% metallic titanium.

Titanium metal has the characteristics of low density, high specific strength, good corrosion resistance, low thermal conductivity, non-toxic and non-magnetic, weldable, good biocompatibility, and strong surface decoration. It is a lightweight, high-strength, corrosion-resistant Structural materials are widely used in high-precision fields such as aerospace, medical equipment, sporting goods, and precision products.

Braun New Luxury Gold 9 Series Shaver

Titanium, which is widely used in the high-precision field, is also used in Braun’s newly launched Braun’s new luxury gold 9 series razor. It is reinforced by a titanium coating to give the skin gentle care and reduce shaving while being strong and corrosion-resistant. Skin is red and swollen when shaving.

The application of titanium in surgical procedures is also worth mentioning. Titanium is “biophilic”. In the human body, it can resist the corrosion of secretions and is non-toxic, and it is suitable for any sterilization method. Therefore, it is widely used in the manufacture of medical equipment, artificial hip joints, knee joints, shoulder joints, flank joints, cranium, active heart valves, and bone fixation clips.

Bone with titanium

Before titanium, stainless steel bones were usually used. However, there is a disadvantage of using stainless steel, that is, it is very painful to take out the stainless steel sheet after the bone has healed. Otherwise, stainless steel will be harmful to the human body due to rust. If you switch to titanium “artificial bone”, orthopedics technology will be completely changed. In the place where the bones are damaged, use titanium sheets and titanium screws. After a few months, the bones will re-grow in the holes and screws of the titanium sheets. The new muscle fibers are wrapped in the titanium sheets, and the titanium bones look like real The bones are connected with flesh and blood, and play a role of support and reinforcement.

Titanium patella claw

The patella claw commonly used in orthopedics is made of titanium. It can be bent into any shape at low temperature in the refrigerator. During the operation, the claw is broken and placed on the fractured patella of the patient. The temperature of the patella claw will rise after the body temperature. When it comes up, it will grip the patella tightly and become a preset shape.

Titanium golf clubs

The characteristics of high strength and low density make titanium widely used in the field of sporting goods. High-quality bicycle frames and golf clubs are usually made of titanium, which is strong and durable.

Titanium aircraft

Titanium is an ideal material for aircraft. Aircraft engines, bullet-proof parts, reinforced parts, reinforced parts, combustion chambers, turbine shafts, turbine discs, nozzles, etc., are mostly made of titanium alloy materials. This is mainly because titanium is good. Heat resistance.

Titanium for aircraft engines

When a supersonic aircraft is flying, the temperature of its wings can reach 500°C. If a relatively heat-resistant aluminum alloy is used to make the wing, one to two or three hundred degrees will be overwhelming. There must be a light, tough, and high-temperature resistant material to replace the aluminum alloy, and titanium can meet these requirements. In addition, titanium can withstand the test of more than one hundred degrees below zero. At this low temperature, titanium still has good toughness without being brittle.

Titanium submarine

With the development and utilization of titanium, it has been discovered that titanium is not only an ideal material for aviation equipment, but also a preferred material for building ships and submarines. Titanium has the reputation of “submerged metal”. Titanium alloy is a hero who climbs into the sky and a hero who dives into the sea. When navigating in the deep sea, submarines have to withstand tremendous pressure. The deeper the dive, the greater the pressure. The shell of nuclear submarine is made of titanium alloy, and its diving depth is more than twice that of ordinary submarine.

Titanium has strong corrosion resistance

Titanium has a strong resistance to acid and alkali corrosion. It will not corrode after 5 years of immersion in seawater, while steel will corrode and deteriorate in seawater. Titanium alloy is used to make the shell of the ship, and the seawater cannot corrode it. The submarine made of it is resistant to seawater corrosion and deep pressure, and its diving depth is 80% higher than that of the stainless steel submarine. At the same time, titanium is non-magnetic and will not be found by mines, and has a good anti-monitoring effect. Generally, steel submarines are easily crushed by water pressure when they dive more than 300 meters. The titanium submarine dives deeper than 300 meters, not only will not be crushed, but also can effectively avoid depth charges, showing the unique charm and excellent performance of the “titanium submarine”.

In addition, we can also find applications of titanium in the construction field. The Guggenheim Museum Bilbao (Guggenheim Museum Bilbao) is a museum dedicated to exhibiting contemporary art works, located in Bilbao, Spain. It was founded by the Guggenheim Foundation in 1997. It is one of the most famous private modern art museums in the world and a chain-operated art venue in the world. Its main building was designed by Frank Gehry (Frank Gehry) and is considered to be the most spectacular deconstructive building in the world. Its appearance is finished with gleaming titanium. The total area of ​​the titanium plate is 27,870 square meters. It is the application of titanium that makes it unique.

It can be seen that as a lightweight, high-strength, corrosion-resistant material, titanium is widely used in high-tech fields such as aerospace, military weapons, medical equipment, sporting goods, high-end products, and construction, and more and more civilian fields are also beginning to use it. This metal, in a sense, the use of titanium has become synonymous with high-end.
