Tungsten Wire Mesh
Tungsten wire mesh is woven with high-purity tungsten wire, featuring ultra-high melting point, high-temperature strength, good corrosion resistance and low thermal expansion. It is widely used in high-temperature furnaces, vacuum environments, aerospace and industrial heating.

Key Properties of tungsten wire mesh:
Melting point: 3422°C (3695.15 K, 6192°F), the highest of all metals.
Service temperature in vacuum / inert atmosphere: up to 2800°C
Density: 19.3 g/cm³ (similar to gold).
Tensile Strength: Very high, but decreases at temperatures above 2000°C.
Very high density & high-temperature strength
Good corrosion resistance in acid, alkali and molten metal environments
Low vapor pressure, suitable for vacuum applications
High electrical & thermal conductivity
Common Applications of tungsten mesh:
· Furnace Heating Elements: Used as heating elements in high-temperature vacuum furnaces for sintering, brazing, and heat treating.
· Furnace Shields (Heat Shields): Used as radiation shields and baffles to contain heat within the hot zone of a furnace.
· Aerospace: Rocket nozzle components, ion thruster grids for spacecraft propulsion, and high-temperature composites.
· Glass and Quartz Melting: Filters and supports for molten glass and quartz, where contamination must be avoided.
· X-Ray Equipment: Grids and collimators for controlling and shaping X-ray beams.
· High-Temperature Filtration: Filtering molten metals or hot aggressive gases in inert environments.
· Vacuum Metalizing: Support screens for evaporation sources in vacuum coating processes.
