Tungsten is a silvery gray metal that's famous for its use as filaments in incandescent bulbs. It is used this way because it has the highest melting point of any metal at 6192 degrees Fahrenheit.
Tungsten is never found in its pure state in nature. The best source of tungsten is a mineral called scheelite, which is comprised of tungsten and calcium. Tungsten's symbol is "W" for "wolfram," which was its original name.
