Distribution and importance of tungsten
From the nozzle of the American Polaris A-3 missile to the tool of machine tool processing, tungsten is inseparable from the participation of the material "tungsten", large to the military field, small to the manufacturing industry, the ability of tungsten can be seen.
We have a preliminary understanding of tungsten. Tungsten has many advantages and has good performance in many industries and fields, and is regarded as a treasure by all countries. The distribution of tungsten resources in the world is mainly concentrated in the Mediterranean and the Atlantic region of Europe, the two sides of the Pacific rim and the Alps - Himalayas.
According to relevant data, by the end of 19th, the reserves of tungsten in the world reached 3.2 million tons.
In addition, tungsten itself has the characteristics of large hardness, strong ductility, high melting point, but also accompanied by air erosion at room temperature, good electrical and thermal conductivity and other related advantages, so it is usually used as steel, alloy and other chemical materials.
Moreover, tungsten's super hardness and wear resistance enable it to be mainly used in the manufacture of various cutting tools, cutting tools, drilling tools and other parts, and is widely used in modern industry in machining, aerospace, military and national defense, electronic information and other fields.
Because of its scarcity and irreplaceability, tungsten is known as the backbone of high-end manufacturing.
