Features of 99.95% high purity tungsten metal powder spherical tungsten powder for
Physical Characteristics
Particle Size: Ranging from nanometers to hundreds of micrometers, the size distribution significantly influences the powder’s flowability, packing density, and sintering behavior.
Shape: Particles can be spherical, irregular, flake-like, or dendritic, each shape affecting the final product’s mechanical properties and surface finish.
Purity: Depending on the production method, metal powders can achieve high levels of purity, critical for applications like electronics and aerospace where impurities can degrade performance.
Density: While less dense than their solid counterparts due to the presence of air between particles, metal powders can be densely packed during processing to approach the density of the solid metal.
Chemical Properties
Reactivity: Some metal powders, particularly aluminum and titanium, are highly reactive with air and moisture, necessitating careful handling and storage under inert atmospheres or vacuum.
Oxidation: Exposure to air can lead to surface oxidation, forming a passive layer that affects sintering and other processes. This can be managed through surface treatment or use of protective atmospheres.

High Purity Tungsten Metal Powder: A Key Ingredient in Advanced Applications
Tungsten, with the chemical symbol W, is a lustrous, hard, and dense metal that holds exceptional properties, making it a highly sought-after material in various industries. The 99.95% high purity tungsten metal powder we offer is of unparalleled quality, ensuring its exceptional performance across numerous applications.
Tungsten powders, particularly spherical tungsten powder, are known for their uniform particle size distribution, which significantly enhances their mechanical stability and processability. Spherical shape grants them an advantage over irregular powders, as they exhibit better flow properties, improved packing density, and reduced agglomeration during handling. This feature is crucial in applications where precise dispersion and compacting are essential, such as in precision engineering, electronics, and aerospace.
In the field of electronics, tungsten’s high melting point (3,410°C) and excellent electrical conductivity make it ideal for use in high-temperature and high-voltage components. As a result, it is commonly employed in the production of filaments, contacts, and heat sinks for semiconductor devices and power electronics. The high purity of our tungsten metal powder minimizes impurities that could potentially degrade these components’ performance.
Aerospace and defense industries rely on tungsten for its lightweight nature and extraordinary strength-to-weight ratio. Spherical tungsten powder is used to create dense, wear-resistant composite materials, often in the form of tungsten carbide or tungsten bronze, for use in armor, missile tips, and cutting tools. The superior hardness and thermal stability of this metal powder ensure that these components can withstand extreme conditions.
In the manufacturing of tungsten carbide, a combination of tungsten and carbon, the high purity tungsten metal powder serves as the base material. This compound exhibits remarkable hardness and wear resistance, making it suitable for wear-resistant coatings, cutting tools, and drill bits in various industries, including mining, automotive, and construction.
In the medical sector, tungsten has unique properties that make it useful for radiation therapy. Spherical tungsten powder is utilized in the fabrication of high-density targets for proton beam therapy, delivering precise and effective dose delivery to cancer cells while minimizing damage to surrounding healthy tissue. The purity of the tungsten ensures consistent results and safety for patients.
Furthermore, tungsten metal powder finds application in pyrotechnics, where it is used to create high-temperature sparks due to its rapid oxidation upon ignition. Its high melting point ensures a longer-lasting and more intense flame, making it a valuable component in fireworks and other special effects.
In summary, the 99.95% high purity tungsten metal powder, specifically the spherical variety, is a versatile material with a wide range of applications. Its exceptional properties, such as high melting point, electrical conductivity, and strength, make it indispensable in sectors like electronics, aerospace, defense, medicine, and pyrotechnics. The uniform particle shape and purity guarantee optimal performance and reliability in each respective industry, highlighting the significance of investing in high-quality tungsten powders.
