Kinds of Metal Tungsten

Tungsten is a brittle metal with a very high melting point. Out of all of the elements only carbon has a higher melting point, and tungsten's melting point is higher than 3300 degrees Celsius. Tungsten is also very hard and scratch-resistant, and metal tungsten rings are very popular. Many men wear them as their wedding rings because they don't scratch and always look new. There are a variety of types of metal tungsten.

Pure Metal Tungsten
Tungsten is element W on the periodic table. It has an atomic weight of 183.84 and its atomic number is 74. It has the highest melting point of any metallic element. In its pure form, it is light gray or white and very brittle. It can be cut with a simple saw or formed into various shapes. Because of this, and its high melting point, tungsten is used in the filaments of a variety of light emitting products such as light bulbs and televisions. Pure metal tungsten is generally obtained from wolframite and scheelite, a mineral. The process by which tungsten is extracted from wolframite was pioneered by two Spanish chemists and mineralogists in 1783.
