Tungsten

In the metal, tungsten has the highest melting point (3420 ℃) and the lowest vapor pressure.Even at the highest temperature of high vacuum technology, tungsten can still meet its performance requirements.Low thermal expansion, high melting point and perfect shape stability make tungsten an excellent material for glass encapsulation.The resistivity of tungsten is an important factor for tungsten to be used as heating material and high temperature furnace material.Tungsten also has high density and good adsorption capacity, so tungsten is also commonly used in the power radiation industry.

At room temperature, tungsten is brittle and difficult to process.But at a slightly higher temperature (200 ℃ -- 500 ℃), the tungsten toughness will be improved greatly.The high-temperature strength and stress of tungsten depend on the processing rate, and the annealing treatment at a certain temperature has a significant effect on the high-temperature strength and stress of tungsten.

Mechanical properties of tungsten: the mechanical properties of tungsten are affected by the purity of the material, the type and amount of alloying elements, heat treatment (annealing conditions), and crystal structure.Tungsten is a body - centered cubic lattice structure with very low ductility at room temperature.Mechanical processing or alloy addition can reduce the brittle and ductile transition temperature of tungsten, and the strength of tungsten increases with the increase of processing rate.Unlike most metals, processing also increases the ductility of tungsten, and the addition of rhenium alloys to tungsten also increases the ductility of tungsten at room temperature.Adding a small amount of La oxide can improve the mechanical properties of tungsten, especially the creep strength.

Chemical properties of tungsten: tungsten and tungsten alloys have similar corrosion resistance.In the case of molten glass, nitrogen, inert gases, molten metals, and ceramic oxides, even at very high temperatures, these substances only slightly erode tungsten as long as no other oxidants are present.

Tungsten and its alloys are widely used in lighting, electronics, medical applications and thin film technology, melting electrodes and high temperature furnaces. Getwick has been engaged in the research and development of tungsten and its alloy materials, and has developed mature production processes and high-performance tungsten materials.
