Introduction to the chemical properties of Zhenan tungsten tubes

High melting point:

Tungsten has a melting point of up to 3422℃, the highest melting point of all metals. This allows tungsten tubes to remain stable in extremely high temperature environments and not melt or deform easily, such as in high-temperature furnaces as a support structure for heating elements or in high-temperature components of aerospace engines.

High density:

The density of tungsten is 19.35g/cm³, close to the density of gold. This high density gives tungsten tubes a good sense of quality and stability, and can be used in special applications that require high-density materials, such as in the field of radioactive protection, where tungsten tubes can be used as shielding materials to block the penetration of radioactive rays.

High strength and hardness:

Tungsten tubes have high mechanical strength and hardness and can withstand greater pressure and mechanical stress. During machining and use, they are not easily worn or deformed, and are suitable for manufacturing parts that require high strength and wear resistance, such as wear-resistant parts in mining machinery.

Good electrical and thermal conductivity:

Tungsten has good electrical and thermal conductivity, although not as good as copper, aluminum and other metals, but in some specific electric heating applications, such as electric heating elements, tungsten tubes can effectively conduct current and generate heat, and can also quickly transfer heat to ensure the normal operation of the equipment.

Corrosion resistance:

Tungsten has good corrosion resistance to most acids, alkalis and salts at room temperature, but it will react with some gases at high temperatures. For example, when heated to a certain temperature in the air, tungsten will react with oxygen to form tungsten trioxide, so when using it, it is necessary to choose appropriate protection measures according to the specific environment.

Zhenan Tungsten Tube Production Process Introduction

Powder Metallurgy:

This is a common method for producing tungsten tubes. First, tungsten powder is made into tungsten billets through pressing, sintering and other processes, and then further processed into tungsten tubes. This method can accurately control the composition and microstructure of tungsten tubes, and produce tungsten tubes with different specifications and performance requirements.

Extrusion method:

After heating the tungsten billet to a certain temperature, it is extruded into a tube through an extrusion die. Tungsten tubes produced by extrusion method have good dimensional accuracy and surface quality, and are suitable for producing tungsten tubes with small diameter and thin wall thickness.

Stretching method:

After the tungsten billet is processed into a tube billet, it is stretched multiple times to reach the required size and shape. The stretching method can improve the strength and toughness of the tungsten tube, but it has high requirements on the quality of the raw materials and processing technology.

Main application areas of Zhenan tungsten tubes

Electronics industry:

Tungsten tubes are widely used in the electronics industry. For example, in electron beam welding equipment, tungsten tubes can be used as cathode materials of electron guns to emit electron beams for welding metal parts; in electron microscopes, tungsten tubes can be used to manufacture filaments of electron guns to generate electron beams for observing microstructures.
Aerospace field: Due to the high melting point, high strength and good thermal shock resistance of tungsten tubes, they can be used to manufacture high-temperature components of aerospace engines, such as combustion chambers, nozzles, etc. These components work under high temperature, high pressure and high-speed airflow, and tungsten tubes can ensure the stability and reliability of their structures.

Medical field:

In medical equipment, tungsten tubes can be used to manufacture shielding components of radiotherapy equipment to protect medical staff and patients from unnecessary radiation damage. In addition, tungsten tubes can also be used to manufacture parts of some medical devices, such as the handles of surgical instruments, etc. Its high strength and wear resistance can meet the requirements of medical operations.

Mechanical processing field:

Tungsten tubes can be used to manufacture various mechanical processing tools, such as handles for milling cutters and turning tools. Its high strength and hardness can ensure the stability of the tool during high-speed cutting, and improve processing efficiency and processing accuracy.

Chemical field:

In chemical production, tungsten tubes can be used to manufacture linings, heating tubes and other components of high-temperature reactors. Its good corrosion resistance and high-temperature stability can ensure the normal operation of chemical equipment in harsh environments.
