Wear Resistant 3*3mm Tungsten Evaporation Pellets

Tungsten 3*3 Evaporation Pellets Packaging Vacuum Packaging 

Tungsten is a silvery white, shiny metal with high hardness and melting point. It is not eroded by air at room temperature and has relatively stable chemical properties. Mainly used for manufacturing filament and high speed cutting alloy steel, super hard die, also used in optical instruments, chemical instruments. China has the world's largest reserves of tungsten. Tungsten also has a lot of properties.

Tungsten is a non-ferrous metal. Metals are usually divided into two groups according to their color and properties: ferrous and non-ferrous. Ferrous metals mainly refer to iron, manganese, chromium and their alloys, such as steel, pig iron, cast iron and so on. Metals other than ferrous metals are called non-ferrous metals. Tungsten belongs to the category of non-ferrous metals.
Tungsten is also the refractory metal with the highest melting point. The general melting point is higher than 1650℃ and there are certain reserves of metal and melting point is higher than the melting point of zirconium (1852℃) metal called refractory metal. Tungsten is also a rare metal. Rare metals usually refer to metals that are found in nature in small amounts or scattered. Tungsten is a widely distributed element, found in almost all kinds of rocks, but in low amounts. The content of tungsten in the crust is 0.001%, and the average content in granite is 1.5×10-6. As a result, it is very difficult to extract tungsten, which can only be separated and extracted by organic solvent extraction and ion exchange. Tungsten is a kind of strategic metal, rare metals are important strategic resources of a country, and tungsten is a typical rare metal, has very important uses. It is an important part of modern high-tech new materials, a series of electronic optical materials, special alloys, new functional materials and organic metal compounds need to use unique properties of tungsten. It's a small amount, but it's essential. Therefore, it is widely used in contemporary communication technology, electronic computer, aerospace development, medicine and health, light-sensitive materials, photoelectric materials, energy materials and catalyst materials.
