Tungsten

Tungsten is a very special metal that people use in many important things. Its symbol is W, and it has the atomic number 74. Tungsten is very strong and can stay solid at very high temperatures, up to 3,422 °C!

Tungsten is found in nature mixed with other elements, in ores like scheelite and wolframite. It was discovered in 1781 and first made into a metal in 1783 by scientists Carl Wilhelm Scheele, Torbern Bergman, and brothers José and Fausto Elhuyar.

Because tungsten is so strong and can handle high heat, it is used to make things like light bulb filaments, very hard materials for cutting and drilling, and strong mixtures of metals called alloys. Tungsten is almost as heavy as uranium or gold, which makes it very useful.

Tungsten is a hard, steel-grey metal that can be tough to shape. But when cleaned, it becomes easier to work with using methods like forging or sintering. Sintering is often used because tungsten has a very high melting point. It is the metal with the highest melting point of all metals!

Tungsten is important in many things we use every day. It helps make strong tools, special lighting, and even parts for airplanes. Even though it is very useful, we need to be careful with tungsten because it can sometimes be harmful if we come into contact with too much of it.
