1. Would you be curious about why tungsten is becoming increasingly important worldwide?
So,And do you know what is tungsten?
First, let's take a look at the physical properties of tungsten.
Tungsten is a naturally occurring metal element, usually extracted from tungsten ores ,such as scheelite and wolframite.
-Tungsten Element symbol: W, atomic number 74, relative atomic mass 183.84
- High Density: About 19.3 g/cm³ (much higher than tantalum's 16.6 g/cm3)
-Ultra-high Melting Point: Up to 3410℃ (the highest among common metals)
-Melting point: Approximately 3400–3420°C, the highest among all metals
-Boiling point: Approximately 5927°
- Specific heat capacity: 24.27 J·mol⁻¹·K⁻¹
- Thermal conductivity: Approximately 173 W·m⁻¹·K⁻¹;
- electrical conductivity approximately 18.1 S/m (only one-third that of copper)
- Resistivity: 5.4 μΩ·cm Baidu Encyclopedia
- Vickers hardness: Approximately 3430 MPa; Brinell hardness approximately 2570 MPa
-Young's modulus: Approximately 411 GPa
-Thermal expansion coefficient: Extremely low (4.5–5.0×10⁻⁶/K), resulting in minimal dimensional changes at high temperatures
Second, The following advantages of tungsten are numerous for your refference .
1). Ultra-high Melting Point , due to it have high melting point , which is why tungsten products can work stably in high-temperature
environments (up to 1800–2000℃).
2). High Density: About 19.3 g/cm³ , So, giving it excellent wear resistance and mechanical stability.
3). Good Electrical & Thermal Conductivity: Second only to copper and silver, making it suitable for conductive components .
4). Chemical Inertness: Inert to most acids, alkalis, and organic solvents at room temperature, ensuring corrosion resistance in harsh working conditions.
5). Non-Radioactive: Pure tungsten and its rare earth-doped alloys are non-toxic and environmentally friendly, complying with ROHS and REACH standards.
Due to tungsten have above excellent physical and chemical properties, Especially with excellent high -temperature resistance and it's irreplaceable
role in core industrial production strategic significance , Nowadays, The tungsten is known as the "Teeth of Industry" as a strategic metal .
Its unique properties cannot be easily replaced by other metals.
It is widely used in national defense, aerospace and other key fields, such as manufacturing armor-piercing projectile cores and aircraft gyroscope rotors. Its stable supply is crucial to the development of the industrial system, further consolidating its status as the "Teeth of Industry".
This is why the importance of tungsten-related products has been receiving increasing attention and emphasis.
