Overview of 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 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.

Parameters of Tungsten Powder
Tungsten powder, also known as wolfram powder, is a high melting point metal used in various applications due to its exceptional strength, density, and resistance to wear. Here are some key parameters for tungsten powder:
1. Chemical Formula: **W** (pure tungsten)
2. Melting Point: **3410°C** (6170°F) – Tungsten has one of the highest melting points among all metals, making it suitable for extreme heat applications.
3. Density: **19.25 g/cm³** – It is very dense, which contributes to its high strength and weight-bearing capabilities.
4. Grain Size: Available in different particle sizes, typically ranging from submicron to several micrometers, with customized options for specific processes like sintering or powders for additive manufacturing.
5. Purity: Can vary from 99.5% to 99.99% (near-pure) depending on the application requirements.
6. Hardness: Tungsten carbide (WC), a compound of tungsten and carbon, is even harder than tungsten itself, with a Vickers hardness of around 3000 HV.
7. Electrical Conductivity: Low compared to most metals, but still conductive enough for some electrical applications.
8. Thermal Conductivity: Fairly high, making it useful for heat sinks or high-temperature components.
9. Oxidation Resistance: Tungsten does not readily react with air, but prolonged exposure can cause surface oxidation.
10. Applications: Tungsten powders are used in industries such as aerospace, electronics, welding, cutting tools, and as an additive in 3D printing for making tungsten carbide parts.
Please note that specific parameters may vary depending on the manufacturer and the type of tungsten powder you are referring to. Always consult the product specifications for the most accurate information.
