= Tungsten: The Superman of all Metals =

Tungsten is a very useful metal. It was discovered in 1783 by two brothers. It has super strength and is resistant to corrosion. This element is also highly ductile. Tungsten has an Atomic weight of 183.84 and an atomic number of 74.

Tungsten has a confusing history because it was being used before it was officially discovered. About 350 years ago it was being used in china to color porcelain. In 1779, Peter Woulfe concluded that an unknown element was in a mineral that he was studying but he neversucceeded in separating it from the mineral. Credit for discovering tungsten goes to brothers Juan José and Fausto Elhuyar. They found the element in the mineral wolframite.

Tungsten has the highest tensile strength of all metals. It is almost as hard as diamond. It is a very durable element. It is also corrosion resistant and has thehighest melting point of all metals (3422ºC). It is ductile so it can easily be made into a wire. It is also conductive so electricity flows through it easily.

Tungsten is often used to make rings because it is strong and doesn’t scratch easily. Because it is ductile and it has such a high melting point, it is used to make lightbulbs. Tungsten can be combined with steel to create things such as power tools and rocket engine nozzles. it is often used in spacecraft and missiles becauseof its strength. Due to its corrosion resistance, a nickel-tungsten alloy could potentially replace chrome and gold-nickel plating. Tungsten is sometimes used as a target for X-ray production. media type="custom" key="23890418" As you can tell, tungsten is extremely useful. It has a long and complicated history but is was definitely worth the trouble of finding it. It has properties that will make it valuable in the future. There are rumors that the United States are stockpiling this element. This metal could possibly replace gold or silver jewelry in the future and could be used in a steel alloy for strength.
