Tungsten (Wolfram) and Advanced Alloys – High-Performance Materials for Extreme Conditions

Tungsten (W) is one of the most remarkable and robust metals used in modern industry. With the highest melting point of all metals – 3420°C, an exceptionally high density of 19.25 g/cm³, outstanding corrosion resistance, low thermal expansion and a very high elastic modulus, tungsten is the preferred choice for components operating under extreme thermal, mechanical and energetic stress.

Tungsten is widely utilized across advanced industrial systems, semiconductor manufacturing, medical and X-ray technologies, high-energy equipment, and selected defense applications where extreme density, thermal stability and structural reliability are essential.
