Tungsten Powder (W Powder)

Tungsten powder is known for its high density, melting point, and hardness. It is produced through the reduction of tungsten trioxide or ammonium paratungstate (APT), with the purity of the product depending on factors such as the temperature of the reduction reaction, the amount of reducing agent, the movement of the container, and the speed of the gas flow.

HM is a reputable supplier of tungsten powders that can be supplied in various particle size ranges (0.4-25 μm). The available purities range from commercial grade to high purity levels, including 3N (99.9% pure), 3N5 (99.95% pure), 4N (99.99% pure), and 4N5 (99.995% pure).

Tungsten Powder Specifications

It is classified into 14 grades according to Fischer's grain size:

*The purity and particle size can be customized according to specific requirements.

About Tungsten Metal

A High-Performance Metal for Extreme Applications

Tungsten is widely recognized for its highest melting point among metals, making it ideal for high-temperature applications. Its remarkable tensile strength and wear-resistant properties ensure that it performs well in demanding environments, such as in cathode ray tubes (CRT) and ray tubes, where durability and heat resistance are critical. The ability of tungsten metal to maintain its integrity under stress makes it a preferred choice in aerospace, electronics, and manufacturing industries.

Additionally, tungsten has low thermal expansion, meaning it can withstand rapid temperature fluctuations without losing its structural integrity. This makes it particularly useful for forming tungsten into complex shapes for precision parts, including those used in heavy equipment and heavy stone-cutting tools. Its density and mechanical properties also contribute to its role as a heavy metal in radiation shielding and other specialized applications.
