Tungsten rod (English name: Tungsten Bar), also known as tungsten alloy rod, is an industrial material with many important functions. Its important functions are mainly reflected in the following aspects:
1. Excellent physical properties
High melting point: The melting point of tungsten rod is extremely high, reaching 3422 degrees Celsius, which makes it have excellent stability and oxidation resistance in high temperature environment, making it an excellent high temperature resistant material.
High density: Tungsten rod has a very high density, which makes it very useful in some applications that need to increase weight or thickness.
High hardness: The hardness of tungsten rod is close to gem grade, second only to diamond, so it performs well in wear and cutting applications.
2. Wide range of application fields
Electrode material:
Tungsten rod in electroplating machine is an important electrode material, which is used to transfer current in electrolyte and plays the role of cathode and anode. Its high melting point and low thermal expansion coefficient make it perform well at high temperature and high current, and have a long service life.
Tungsten electrode is also a commonly used electrode material in metal welding such as aluminum welding.
Aerospace:
Due to the excellent high temperature resistance of tungsten rods, it is widely used in the aerospace field, such as making high temperature engine and spacecraft parts to withstand extreme heat and pressure conditions.
Homogenization and stirring:
The high density and hardness of tungsten rods make it often used to evenly mix and stir materials and prepare high-precision mixing equipment in the chemical industry.
X-ray and radiation protection:
The high density and high absorption capacity of tungsten rods make it widely used in the field of X-ray and radiation protection, such as shielding materials in medical imaging.
Cutting and wear tools:
The high hardness of tungsten rods makes it an ideal material for preparing cutting and wear tools, such as processing stainless steel and titanium and other metal materials with higher hardness.
Other applications:
Tungsten rods are also used in glass melting, high temperature furnace heating elements, structural parts, filaments and other fields. For example, the wire drawn from tungsten rods can be used as filaments in light bulbs, electron tubes, etc.
3. Strategic significance
Tungsten is an important strategic metal. Its content in the earth's crust is relatively low, but it has extremely high application value. The wide application of tungsten rods not only promotes the development of many industries, but also plays an important role in national security, scientific and technological progress, etc.
In summary, tungsten rods play an important role in industrial production, scientific research, aerospace and other fields with their excellent physical properties and wide application fields. With the continuous advancement of technology and the continuous expansion of applications, the importance and value of tungsten rods will be further reflected.
