Tungsten Foam Applications

Defense and Military: The high strength and high-temperature resistance of tungsten foam have led to its use in protective armor and ballistic protection materials.
Atomic Energy: Due to its good corrosion resistance and high-temperature stability, tungsten foam is used as structural and shielding material in nuclear reactors.
Aerospace: The lightweight and high-strength properties of tungsten foam make it suitable for structural components and protective systems for aerospace vehicles.
Electronic information: tungsten foam’s high thermal conductivity and electrical conductivity make it important in the heat dissipation materials of electronic devices and electromagnetic shielding materials.

Tungsten Foam Packaging

The Tungsten Foam is carefully placed in wooden cases or cartons, with additional support from soft materials, to prevent shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
