Discovery
So what are some historical facts about tungsten? It’s an element that was discovered back in 1783 by two Spanish chemists. They found it in samples of a mineral called wolframite. Perhaps this is why tungsten is sometimes referred to as “wolfram.” And that’s why tungsten’s symbol on the periodic table is “W.” As for the word tungsten, it comes from the Swedish words “tung” and “sten,” which mean “heavy stone.”
Aso nei, tungsten is still primarily extracted from wolframite. Ma, of all metals in pure form, tungsten o loʻo i ai le maualuga faʻaliʻaliʻuga vaega (6192 tikeri Fahrenheit) and the lowest vapor pressure (at temperatures above 3000 tikeri Fahrenheit). It also has the highest tensile strength.
Tungsten Uses
What is tungsten used in/for? Ia, it’s found in many industries and products, including cutting tools, ammunition, lighting, jet turbine engines and fishing weights.
Tungsten wire is a popular product. How is tungsten wire diameter expressed? It’s done in milligrams. The formula to calculate the diameter of tungsten wire based on the weight per unit length is D = 0.71746 x square root (mg weight/200 mm length). Tungsten wire often comes doped.
What about tungsten carbide? It actually doesn’t have that much tungsten in it. Known for its wear resistance, tungsten carbide can only be cut using diamond tools. Cobalt is usually added as a binder, making it a cemented carbide. So, tungsten and tungsten carbide are not interchangeable.
Can you get liquid tungsten? With such a high melting point, it’s difficult to melt tungsten. I le talitonuga, it can be melted, but in reality, it’s just not practical. Think about this: what kind of container could even hold liquid tungsten? It would probably be melted away by its high temperature! O le mea lea, tungsten is manufactured in a non-liquid state.
