Tungsten




Properties

      Highest melting point of all metals: 3,420 degrees Celsius/6,188 degrees Fahrenheit (iron = 1,536 degrees Celsius/2,768

         degrees Fahrenheit)

       High density: 19.3 g/cm³

       Low vapor pressure

       Low thermal expansion

       Good thermal conductivity
