Tungsten (W)
Though detected in 1779, tungsten wasn't isolated until 1883.
Pure tungsten is a gray and white metal. It can be cut with a saw, forged, spun, drawn, and extruded, but is brittle and somewhat difficult to handle. It oxidizes in air, cannot tolerate high temperatures, and has excellent corrosion resistance. Natural tungsten contains five stable isotopes and twenty-one unstable isotopes are known.
Tungsten and its alloys are used as filaments in electric lamps, electron and television tubes, for metal evaporation work, and as electrical contact points for automobile distributors.
