STA Tungsten is remarkable for its robust physical properties. Tungsten has the highest melting point 34220C, lowest vapor pressure and expansion factor, excellent barrier ray ability and the highest tensile strength at very high temperatures of all metals. It’s corrosion resistance property is excellent.
The advantages of Tungsten:
**High melting point (3422°C)
**Sufficiently high electrical resistant
**Low vapor pressure
** Low thermal expansion combined with good thermal conductivity
** Extremely good corrosion resistance against Glass&Ceramics.
