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.”
I teie mahana, tungsten is still primarily extracted from wolframite. E, of all metals in pure form, e vahi faaoraa teitei roa a'e to te maa (6192 teteri Mahana) and the lowest vapor pressure (at temperatures above 3000 teteri Mahana). It also has the highest tensile strength.
Tungsten Uses
What is tungsten used in/for? Maitai roa, it’s found in many industries and products, including cutting tools, ammunition, Te mau mana'o tauturu no te, Te mau mītini turbine e te mau poria.
