Tungstène

Le tungstène est un métal rare. Les métaux rares se réfèrent généralement à des métaux avec moins de contenu ou une distribution rare dans la nature. Le tungstène est un élément largement répandu, qui existe dans presque tous les types de roches, mais sa teneur est faible.

Le tungstène est un métal stratégique. Comme on le sait, les métaux rares sont d'importantes ressources stratégiques nationales. Le tungstène est un métal rare typique et ses applications sont extrêmement importantes. C'est un élément essentiel des nouveaux matériaux-modernes de haute technologie.

3. Tungsten plate characteristics: high melting point, high strength and hardness, good performance at high temperature, low resistivity, small expansion coefficient, and small electronic work function.

4. It is the most broadly used metal material under high-temperature conditions. Our company produces all kinds of plates, tubes, rods, crucibles, ingots, and large-scale special-shaped products made of pure tungsten, such as  electronic tube components, high-temperature furnace parts, high-temperature crucibles, semiconductors, lamp anode, various electrodes, glass industry parts, thermowells, porous bodies, and composites, etc

Tungsten crucibles, tungsten tubes, tungsten plates, and tungsten-rhenium alloys are important parts of sapphire crystal growth furnace and MOCVD; various kinds of large tungsten pipes, mandrels, forming plates and feeding plates are important parts of high-temperature furnaces such as quartz glass furnaces; tungsten tubes, tungsten crucibles, and electrodes are also fundamental consumables the rare earth smelting industry. 

5. The most important advantage of tungsten plate is that it has good high-temperature strength and good corrosion resistance to molten alkali metals and vapors. Only when tungsten is above 1000 degree can oxide volatilization and liquid oxide occur. However, it also has the disadvantage of high plastic-brittle transition temperature and difficulty in plastic processing at room temperature. Refractory metals represented by tungsten have been commonly used in electronics, metallurgy, light source, machinery, chemical industry, and other industries.
