Pure Molybdenum wire mesh
Pure Molybdenum(Mo) wire mesh is woven with high-purity molybdenum wire. It has high melting point(6th highest melting point of all elements), good high-temperature strength, low thermal expansion and excellent electrical/thermal conductivity, widely used in high-temperature furnaces, vacuum and semiconductor industries.

Key Properties of pure mo wire mesh:
Melting Point: 2623°C (4753°F)
Continuous service temperature (vacuum / H₂ / inert gas): up to 1800°C
Density: 10.2 g/cm³ (about half that of tungsten)
Tensile Strength: High, with good strength retention up to ~1800°C
Thermal Conductivity: Excellent (about twice that of stainless steel)
High elastic modulus & good creep resistance at high temperature
Low vapor pressure, suitable for vacuum environment
Good corrosion resistance to many molten metals
Non-magnetic
Common Applications
Furnace Heating Elements: Used as resistance heating elements in vacuum furnaces for sintering, brazing, and heat treating.
Heat Shields (Radiation Shields): Used in multiple layers to contain heat within the hot zone of a furnace, improving energy efficiency.
Ion Implantation Grids: In semiconductor manufacturing, high-purity molybdenum grids are used in ion implanters.
High-Temperature Filtration: Filtering molten metals (e.g., aluminum, zinc) and aggressive molten salts.
Aerospace: Components in rocket nozzles and thrusters where high heat resistance is required.
Glass Processing: Supports and stirrers for molten glass.
Sapphire Growth Furnaces: Used in the production of synthetic sapphire for LEDs and watch crystals.
