Tungsten is a hard, heavy, grey-white, metallic element. It has the highest melting point, lowest vapor pressure and the highest tensile strength at temperatures above 1650 °C of any metal. It is virtually resistant to corrosion due to an oxide film on its surface. It is ductile and can be drawn into a very thin metal wire, and is widely used in light bulb filaments.
