Exploring the secrets of high-end nanometal materials: Nanotungsten known as the "teeth of industry"

Tungsten, a name that sounds a little strange, has actually already penetrated into our lives. It has an extremely high melting point, up to 3410℃, and is one of the metals with the highest melting points in nature. It is known as the “teeth of industry.” This property enables it to maintain stable physical and chemical properties in high temperature environments, making it a leader in heat-resistant materials. For this reason, tungsten is widely used in traditional industrial fields. For example, in the lighting industry, tungsten filaments are the key light-emitting components in early incandescent bulbs. When current passes through the tungsten filament, the tungsten filament will glow due to heat, bringing us light.

The history of tungsten can be traced back to the late 18th century, but it was not until the late 19th century that tungsten was gradually used in industrial production with the advancement of smelting technology. From the initial carbide tools to modern aerospace materials, tungsten has become an indispensable element of modern industry with its high hardness, high melting point, high density and excellent wear resistance.

However, the legend of tungsten is far more than that. With the rise of nanotechnology, scientists began to try to prepare tungsten into nanomaterials. New nano tungsten materials such as nano tungsten powder, nano tungsten wire, and nano tungsten film continue to emerge, opening up a new field for the application of tungsten. So, what are the characteristics and advantages of these nanoscale tungsten materials?

Characteristics and advantages of nano tungsten
