Porous tungsten, as a special material, has advantages and disadvantages in the following aspects:
The advantages of porous tungsten:
Excellent physical performance
Porous tungsten has excellent physical properties, such as low density, high stiffness, large specific surface area, good energy absorption and vibration reduction performance, good noise reduction effect, and high electromagnetic shielding performance.
Good permeability
Porous tungsten has good permeability, controllable pore size and pore size, and stable shape, which makes it excellent for applications in situations that require specific pore structures.
High temperature resistance and thermal vibration resistance
Porous tungsten materials have a high melting point (tungsten has a melting point of up to 3420 ℃) and good thermal stability, which allows them to maintain good performance in high-temperature environments.
Wide application fields
Porous tungsten has a wide range of applications in fields such as electronic machinery, aerospace, thermal spraying, and powder metallurgy materials, such as cathode materials for high-power microwave tubes, high-temperature fluid filtration materials, and beam target materials.
