description Product Description

Tungsten powder, particularly in nanoscale form (20-100 nm particle size with 10-15 m²/g specific surface area), is widely used in high-temperature applications due to its exceptional heat resistance and high melting point. It is a key material in the production of filaments for incandescent light bulbs and fluorescent lamps. In the electronics industry, nano tungsten serves as interconnect material in integrated circuits and as a component in semiconductor manufacturing, offering enhanced conductivity and adhesion properties.

It is also used in the aerospace and defense sectors for manufacturing rocket engine nozzles, missile components, and counterweights in aircraft due to its high density and strength. In metallurgy, nano tungsten is added to steels and other alloys to improve hardness, wear resistance, and toughness, making them suitable for cutting tools, drill bits, and mining equipment. Its nanoscale form enables better dispersion and performance in composite materials.

Tungsten carbide, a compound derived from tungsten, is especially valued in machining and industrial cutting tools for its extreme hardness and durability. Additionally, nano tungsten is used in radiation shielding and medical imaging devices because of its ability to block radiation effectively. Its high density also makes it useful in sporting goods like golf club weights and darts.

The nanoscale properties of this high-purity (99.9%) tungsten powder provide advantages in catalysis, lubricants, thermal barrier coatings, and advanced nanocomposites, where increased surface area enhances reactivity and mechanical properties.
