Titanium is the most durable metal. Which metal is considered the most durable. Industrial applications of titanium

From childhood, we know that the most durable metal is steel. Everything iron we associate with her.

Iron man, iron lady, steel character. When we say these phrases, we mean incredible strength, strength, hardness.

For a long time, steel was the main material in production and armament. But steel is not metal. More precisely, it is not entirely pure metal. This is with carbon, in which other metallic additives are present. By using additives, i.e. change its properties. After that, it is processed. Steel making is a whole science.

The strongest metal is obtained by introducing appropriate master alloys into the steel. It can be chromium, which also gives heat resistance, nickel, which makes steel hard and elastic, etc.

In some areas, steel began to replace aluminum. Time passed, the speed grew. Aluminum could not stand it either. I had to turn to a titan.

Yes, because titanium is the most durable metal. To give the steel high strength characteristics, titanium was added to it.

It was discovered in the 18th century. Due to its fragility, it was impossible to apply it. Over time, having received pure titanium, engineers and designers became interested in its high specific strength, low density, corrosion resistance and high temperatures. Its physical strength is several times greater than that of iron.

Engineers began to add titanium to steel. The result is the most durable metal that has found application in an ultra-high temperature environment. At that time, no other alloy could withstand them.

If you imagine an airplane flying three times faster than you can imagine, how the cladding metal heats up. Sheet metal the skin of the aircraft in such conditions heats up to + 3000C.

Today titanium is used unlimitedly in all areas of production. These are medicine, aircraft construction, and shipbuilding.

With all the evidence, we can say that in the near future the titan will have to move.

Scientists from the United States, in the laboratories of the University of Texas at Austin, discovered the thinnest and most durable material on Earth. They called it graphene.

Imagine a plate as thick as one atom. But such a plate is stronger than diamond and a hundred times better conductive to electric current than computer silicon chips.

Graphene is a material with damaging properties. He will soon leave the laboratories and rightfully take his place among the most durable materials in the universe.

It is even impossible to imagine that a few grams of graphene would be enough to cover a soccer field. This is metal. Pipes made of such material can be laid manually without the use of lifting and transport mechanisms.

Graphene, like diamond, is the purest carbon. Its flexibility is amazing. Such material is easy to bend, folds perfectly and rolls up perfectly.

Manufacturers of touch screens have already begun to look closely at it, solar panels, cell phones, and finally super-fast computer chips.

If by strength it is customary to understand the ability of solids to resist destruction and maintain the shape of a product, then the following metals can be attributed to super-strong and durable metals.

Name titanium was appropriated by Martin Klaproth, a German explorer who discovered a new metal not by his chemical qualities, and in honor of the mythological heroes of the children of the earth - the titans.

Finding titanium in nature is in 10th place, most of all it is concentrated in minerals. Without this metal, the latest discoveries in the field of rocket, ship and aircraft construction would be impossible. Titanium is used in all areas of industry, in the manufacture of medical implants and body armor with Food Industry and agriculture.

2nd place

Light gray tungsten , literally translated as wolf cream, is the most refractory metal, therefore it is indispensable in the manufacture of heat-resistant surfaces and products. The filament in a conventional light bulb is made of tungsten filament.

That metal is used in ballistic missiles, in the manufacture of shells and bullets, in gyroscopic ultra-high-speed rotors.

3rd place

Tantalum it is almost impossible to modify, because it begins to melt at a temperature of 3015 degrees Celsius, and boils at a boiling point of 5300 degrees. To an ordinary person such heat is even impossible to imagine. The bluish-gray metal is the most indispensable in modern medicine; it is used to make wires and sheets that cover damaged bones.

Opened in 1817 molybdenum, gray-steel metal in its pure form is practically not found. The refractoriness of this metal, the melting point of which exceeds 2620 degrees, is striking. The greatest application of molybdenum is found in the military industry, where gun and armored steels are made.

5th place

Aviation and mechanical engineering, nuclear power and astronautics use niobium, very similar in properties to tantalum metal. Niobium is practically not affected by any substances, neither salts nor acids, it is difficult to melt, and it is difficult to oxidize, which is what made the unique metal so popular.

6th place

The heaviest metal on earth iridium possesses the most persistent anti-corrosion properties, even aqua regia cannot melt it. The addition of iridium to other alloys increases their ability to resist corrosion.

7th place

Beryllium is one of the rare metals that are mined in the earth. Its unique qualities, such as high thermal conductivity and fire resistance, have made this metal indispensable in the manufacture nuclear reactors... Beryllium alloys rightfully occupy a leading position in the aerospace and aviation industries.

8th place

Light blue chrome , which is also one of the most durable metals, due to its unique properties when added to alloys, steels make them harder and more resistant to corrosion. Chrome parts have a beautiful appearance that does not change over time.

9th place

The Saxons treat their legends with care, the name of the hero of one of them, Kobold, was immortalized in the name of the metal - cobalt ... Quite often, when mining ore, prospectors mistook the gray-pink metal for silver.

Refractory metal, as an additive, increases the heat resistance, hardness and wear resistance of steel. Due to its unique qualities, cobalt is indispensable in metal-cutting machines.

Hafnium - light gray metal, unique in its qualities, is mined from zirconium ore. Hard, refractory hafnium has a unique feature, the fact is that its temperature-capacity dependence is abnormal and does not fall under any laws of physics.

Hafnium is used in nuclear power and in optics, for the strengthening of various alloys and the manufacture of glass for X-ray, it is difficult to imagine military production without it.

Like boron nitride of the wurtzite modification, this compound is extremely rare. Sometimes lonsdaleite is formed when meteorites, which include graphite, collide with the Earth.

Many lovers interesting facts interested in the question, which metal is the hardest? And it won't be easy to answer this question offhand. Of course, any chemistry teacher can say it right without even thinking about it. But among ordinary citizens who last studied chemistry at school, not many will be able to give an answer correctly and quickly. This is due to the fact that since childhood everyone is accustomed to making various toys out of wire and remembered well that copper and aluminum are soft and lend themselves well to bending, but on the contrary, it is not so easy to give the desired shape. A person most often deals with the three named metals, so he does not even consider the rest of the candidates. But steel is certainly not the hardest metal in the world. In fairness, it should be noted that this is not a metal at all in the chemical sense, but a compound of iron with carbon.

What is titanium?

The hardest metal is titanium. For the first time, pure titanium was obtained in 1925. This discovery made a splash in scientific circles. Industrialists immediately drew attention to the new material and appreciated the benefits of its use. According to the official version, the most hard metal on Earth got its name in honor of the indestructible Titans, who, according to ancient Greek mythology, were the founders of the world.

According to scientists, the total world reserves of titanium today amount to about 730 million tons. At the current rate of extraction of fossil raw materials will be enough for another 150 years. Titanium ranks 10th in natural reserves among all known metals. The world's largest titanium producer is Russian company VSMPO-Avisma, which satisfies up to 35% of the world's needs. The enterprise is engaged in a full cycle of processing from ore mining to manufacturing various products... It takes about 90% Russian market for the production of titanium. About 70% finished products goes for export.

Titanium - light metal silver in color with a melting point of 1670 degrees Celsius. Shows high chemical activity only when heated, under normal conditions does not react with most chemical elements and compounds. It is not found in nature in its pure form. It is distributed in the form of rutile (titanium dioxide) and ilmenite (a complex substance consisting of titanium dioxide and ferrous oxide) ores. Pure titanium is extracted by sintering the ore with chlorine, and then displacing the more active metal (most often magnesium) from the resulting tetrachloride.

Industrial applications of titanium

The hardest metal has a fairly wide range of uses in many industries. Amorphous atoms provide titanium with the highest level of tensile and torsional strength, good impact resistance, and high magnetic properties. Metal is used for the manufacture of cases air transport and missiles. It copes well with the enormous loads that machines experience on themselves, being at great heights. Titanium is also used in the manufacture of hulls for submarines, as it is able to withstand high pressure at great depths.

In the medical industry, metal is used in the manufacture of prostheses and dental implants, as well as surgical instruments. As an alloying additive, the element is added to some steel grades, which gives them increased strength and resistance to corrosion. Titanium is well suited for casting as it produces perfectly smooth surfaces. It is also used for making jewelry and decorative items... Titanium compounds are also actively used. Dioxide is used to make paints, whitewash, and is added to paper and plastic.

Complex organic titanium salts are used as a hardening catalyst in paint and varnish production. Titanium carbide is used to make various tools and attachments for processing and drilling other metals. In precision engineering, titanium aluminide is used to produce wear-resistant elements that have a high margin of safety.

The hardest metal alloy was obtained by American scientists in 2011. It includes palladium, silicon, phosphorus, germanium and silver. New material was named "metallic glass". He combined the hardness of glass and the plasticity of metal. The latter prevents cracks from spreading like they do with standard glass. Naturally, the material was not launched into wide production, since its components, especially palladium, are rare metals and are very expensive.

At the moment, the efforts of scientists are aimed at finding alternative components that would preserve the obtained properties, but significantly reduce the cost of production. However, individual parts for the aerospace industry are already being produced from the resulting alloy. If alternative elements can be introduced into the structure and the material becomes widespread, then it is quite possible that it will become one of the most demanded alloys of the future.
