FeW70 80

 

Tungsten, a metal. The atomic number of tungsten element is 74, and the atomic weight is 183.84. Steel gray or silvery white, with high hardness, high melting point, and is not corroded by air at room temperature; it is mainly used for manufacturing filaments and high-speed cutting alloy steel, super-hard molds, and is also used in optical instruments and chemical instruments. China is the world's largest tungsten reserve country.

Tungsten is a non-ferrous metal. Usually people divide metals into two categories according to their color and properties: ferrous metals and non-ferrous metals. Ferrous metals mainly refer to iron, manganese, chromium and their alloys, such as steel, pig iron, iron alloys, cast iron, etc.

Metals other than ferrous metals are called non-ferrous metals. tungsten belongs to the category of non-ferrous metals. the strength and hardness of non-ferrous alloys are generally higher than those of pure metals, their resistance is greater than that of pure metals, their temperature coefficient of resistance is smaller, and they have good comprehensive mechanical properties. therefore, as a non-ferrous metal, tungsten is extremely strong and hard.

Tungsten is the refractory metal with the highest melting point. Generally, metals with a melting point higher than 1650°C and with certain reserves and metals with a melting point higher than the melting point of zirconium (1852°C) are called refractory metals. Typical refractory metals are tungsten, tantalum, molybdenum, niobium, hafnium, chromium, vanadium, zirconium and titanium. As a refractory metal, the most important advantages of tungsten are its good high-temperature strength and good corrosion resistance to molten alkali metals and steam. Tungsten only evaporates oxides and liquid oxides above 1000°C.
