For the first time Carl Wilhelm rejected an acid called tungstenic acid. After a while, a scientist named Bergman found that if we reduced the amount of this acid, a new metal called tungsten would be made.
Tungsten is a chemical element that symbolizes W and its atomic number is 74. This metal is a very rare metal that in nature is often not found purely, but can be found with other materials and elements. One of the types of mineral stones that have tungsten is wolframite and shuelite.
Tungsten metal has the highest melting point among other metals at 3422. Also, its boiling point is 5555 °C, which is the highest boiling point.
Tungsten has very high hardness and fragility and is inherently hard. This hardness has made the work hard and the extraction of this metal. Tungsten has different alloys and these alloys have different applications. Tungsten alloys are used in the manufacture of a variety of incandescent lamps.
Tungsten in raw and non-pure mode is a hard gray and steel paint metal. Normally, this metal is crisp and very difficult to work with. To solve this problem, purification operations are performed on it and therefore this metal achieves the necessary hardness and achieves the necessary ductility.
Tungsten metal can be formed by forging, stretching and extruding operations.
Tungsten metal shows private resistance to oxidation, acid and openness. Tungsten is normally combined with oxygen and forms a yellow tungsten trioxide compound.
Due to the strength and density of tungsten, alloys of this material are used to make a variety of heavy metal alloys. In some of these alloys, 18% tungsten is used. Due to the high melting point of tungsten, these alloys are very suitable for use in rocket nozzles.
Tungsten superalloys also use turbine blades and abrasion resistant parts and metal coatings.
Tungsten metal rods are often made of metal powder at certain temperatures. This rod is made using new technologies at very high temperatures. These rods have very low thermal expansion coefficient, high thermal conductivity and good strength and strength.
Adding more alloying components to tungsten metal rods makes these rods suitable for use in machining and soldering .
Tungsten metal has different applications, the most important of which are as follows :
1. Since the melting point of tungsten is high, this metal is used in a variety of welding and soldering of electronic components.
2. Tungsten alloys are used to make lead pellets.
3. Tungsten-containing salts are used in chemical salts.
4.Tungsten bronze along with other materials are used in dyeing.
5.Tungsten is used in the manufacture of metal electrodes
6.Use in metalworking industries
7.Used in the manufacture of oil and gas extraction equipment
8.Use in construction industry
9.Making alloy steels
10.Build detector types
11.Use in high temperature control technology
12.Production and radiation of X-ray
13.Making super alloys
