Overview of High purity 99.95% pure tungsten powder Tungsten powder stock
High purity 99.95% pure tungsten powder Tungsten powder stock comprises a broad category of finely divided, solid particles derived from various metals or metal alloys. These powders exhibit unique characteristics that make them indispensable in modern manufacturing and advanced technologies.
Key Characteristics of High purity 99.95% pure tungsten powder Tungsten powder stock
-
Particle Size and Distribution: The size and uniformity of particles significantly influence flowability, packing density, and the final product’s mechanical and physical properties. Finer powders generally offer a larger surface area, which is beneficial for reactions and sintering but may also increase aggregation.
-
Composition: Metal powders can be elemental (pure metal) or alloyed, combining two or more metals to achieve desired properties such as enhanced strength, corrosion resistance, or electrical conductivity.
-
Shape: Particle shapes range from spherical to irregular or flake-like. Spherical powders provide better flowability and packing, while flake-shaped powders are suited for coatings and electronic applications due to their unique orientation and surface area.
-
Purity: Depending on the application, metal powders can be highly purified to remove impurities, critical for uses in electronics, aerospace, and medical devices where contamination could compromise performance.

Parameters of High purity 99.95% pure tungsten powder Tungsten powder stock
High purity tungsten powders, with a purity level of 99.95%, are commonly used in various applications due to their exceptional properties. Here are some key parameters for tungsten powder, often found in stock:
1. **Material**: Tungsten (W), an element with the atomic number 74 and chemical symbol W.
2. **Purity**: 99.95% W – This indicates that the tungsten powder contains less than or equal to 0.05% impurities, typically consisting of other elements like carbon, oxygen, or silicon.
3. **Particle Size Distribution**: Available in different grades, usually specified as a range such as 325 mesh (45 microns) to 400 mesh (30 microns) or customized according to customer requirements. Finer particle sizes can be achieved through milling processes.
4. **Density**: Tungsten has a high density of approximately 19.25 g/cm³, which contributes to its strength and weight-bearing capabilities.
5. **Melting Point**: Tungsten has a very high melting point of about 3,410°C (6,170°F), making it an excellent choice for high-temperature applications.
6. **Coefficient of Thermal Expansion (CTE)**: Low CTE, around 4.5 x 10^-6 /°C, which helps maintain dimensional stability under temperature variations.
7. **Resistance to Oxidation**: Tungsten is chemically inert at high temperatures, making it resistant to oxidation, which is crucial for applications like tungsten filaments, electrodes, and targets.
8. **Hardness**: Tungsten carbide (WC), a compound of tungsten and carbon, is extremely hard, but pure tungsten powder itself is relatively soft.
9. **Applications**: Tungsten powder finds use in industries like aerospace, electronics, welding, cutting tools, lighting (such as halogen bulbs), and as a component in high-performance materials like refractory ceramics.
10. **Storage**: It’s important to store tungsten powder in a dry, cool place to prevent oxidation and maintain its purity.
Please note that specific parameters may vary depending on the manufacturer and the exact grade of tungsten powder you are referring to. Always consult the product data sheet for the most accurate information.
