Biological Rating
Necessary for all life.
Description
Named from the Swedish word meaning “heavy stone,” tungsten is a gray-white metal that is stable and unaffected by air, acids or bases. It has the highest melting point of any metal and often is used in alloys that must resist great amounts of heat, such as light-bulb filaments. Tungsten also is used in television tubes, paints, high-temperature lubricants, tanning leather and fluorescent lighting. Tungsten is commonly alloyed with carbon forming tungsten carbide which has a very high melting point and increased hardness. It is used in high-strength applications, such as furnaces, missiles, dental drills and other cutting tools. The symbol for tungsten, W, comes from tungsten’s Latin name Wolfram. The Latin name is derived from the tungsten mineral wolframite.
