Overview of Spherical Tungsten Powder Nano Tungsten Alloy Powder Pure Tungsten Powder
Tungsten is a metallic element with the element symbol W and atomic number 74. It is located in the VIB group of the sixth period of the periodic table of elements. In nature, tungsten mainly exists in the form of hexavalent cations. Its ionic radius is small, it has strong polarization ability, and it is easy to form complex anions.
When preparing pure tungsten or tungsten alloy, the main methods include powder metallurgy, smelting (including electron beam melting, vacuum melting, plasma beam melting) and chemical vapor deposition.
Feature of Spherical Tungsten Powder Nano Tungsten Alloy Powder Pure Tungsten Powder
The thermal expansion coefficient of tungsten is very low, only 4.5×10^-6 m/mK, so it has good thermal stability. These properties make tungsten widely used in manufacturing high-temperature components and reliable heat detectors.

– Density: About 19.3 g/cm³
– Melting Point: 3410°C (6170°F)
– Hardness: Very high, 8.5 on the Mohs scale
2. Nano Tungsten Alloy Powder:
– Composition: Can be a mixture of tungsten with other elements like carbon (WC), cobalt (WCo), niobium (Nb), or titanium (WTi) for enhanced properties
– Particle Size: Nanoscale, typically less than 100nm
– Purity: Generally higher than 95%, but composition-dependent
– Hardness and wear resistance: Improved due to alloying elements
– Melting Point: Dependent on the alloy composition
– Specific applications: Used for wear-resistant coatings, cutting tools, and advanced electronics
3. Pure Tungsten Powder:
– Composition: 100% pure tungsten
– Particle Size: Similar to spherical tungsten powder, but with no alloying elements
– Purity: 99.99% or higher, extremely pure
– Properties: Same as spherical tungsten powder but without the benefits of alloying
– Applications: High-temperature applications, radiation shielding, and precision components
These parameters can vary depending on the supplier and specific grades. Always consult the manufacturer’s datasheet for the most accurate information.
