High-Melting-Point Material With Dimensional Stability
Tungsten has the highest melting point of all metals and remains dimensionally stable under both thermal and mechanical stress. Its low coefficient of thermal expansion reduces dimensional deviation during fast temperature shifts. Due to its high density and resistance to radiation and corrosion, the material is used in environments with extreme conditions.

Key Material Properties
High Melting Point
With a melting point of 3422 °C, tungsten has the highest melting temperature of all metals and is used in extreme high-temperature applications.
Density
At 19.3 g/cm³, tungsten has the highest density among all metals, meeting mass and radiation requirements in sensitive applications.
Radiation Shielding
Due to its high density, tungsten attenuates X-rays and gamma radiation and is used in shielding components.
Environmental Compatibility
In its pure state, tungsten is non-toxic and fully recyclable.
Fields of Application
Examples of Use
Tungsten is used in applications involving extreme temperatures. Common applications include heating coils, filaments in vacuum or high-temperature environments, and incandescent filaments in lighting technology. In industrial furnaces, it is used as a protective layer to reflect thermal radiation and reinforce surrounding structures.
For mechanical stress scenarios, tungsten alloys are found in cutting and wear-resistant inserts as well as in forming tools where hardness, precision and durability are essential.
Thanks to its high density, tungsten is also used as flywheels, counterweights or shielding elements where radiation or kinetic energy must be managed precisely.
