The name “tungsten,” as well as the tale of why the symbol of the element is W on the periodic table is an international problem. The component itself was discovered back in 1783 by two Spanish drug stores, bros Juan José as well as Fausto Elhuyar, in examples of a mineral called wolframite.
Today, in numerous countries around the globe, tungsten is referred to by the Germanic name “wolfram,” after the mineral wolframite. So, it’s easy to see where the chemical sign W came from, although if you resemble us, you could ask yourself why the aspect had not been called “Faustonite” or if there is a Spanish word for wolframite.

Nevertheless, the name tungsten is what is utilized today in the United States, as well as in French, England, as well as various other languages. This term came from the Swedish words tung as well as sten, implying “heavy stone,” as well as is the old Swedish name for the mineral scheelite, another resource of tungsten ore.
Yet ironically, tungsten is NOT utilized as the name of the element in Sweden or the other Nordic countries. There, as well as in a lot of Germanic as well as Slavic languages, they utilize the name wolfram or volfram.
Tungsten/Volfram/Wolfram is still removed largely from wolframite and scheelite. Of all steels in pure kind, tungsten has:
- The highest possible melting point of 6192°F, or 3422°C)
- The greatest tensile strength
- Cheapest vapor pressure at temperature levels over 3000°F, or 1650°C
So, whether you call it tungsten or any other name, this series of properties suggests tungsten is used in lots of markets as well as items worldwide, from high-speed cutting devices as well as jet turbine engines, to lighting, ammo, as well as even ﬁshing weights.
Many Tungsten Cord Comes Doped Whether You Required It This Way or Not!
Once again, the technique goes back to the old days, especially, a time when the primary function of tungsten cable remained in filaments for light bulbs. The difficulty was, light bulbs shake off white-hot temperatures that triggered early filaments to droop, leading to light failure.
Through testing, the idea progressed to add silica, alumina, as well as potassium to change the mechanical buildings of the tungsten wire. The dopants were included in the powder blending phase.
Interestingly, in the procedure of hot swaging as well as warm drawing the tungsten wire, the alumina as well as silica would out-gas and the potassium would stay. This aspect provided the cable non-sag buildings under white-hot temperatures.
