Tungsten mesh is a high-performance material known for its exceptional strength, high melting point, and resistance to extreme environments. It is used in applications where most other metals (like steel, titanium, or zirconium) would fail due to heat, wear, or corrosion.
Key Properties of Tungsten Mesh:
- Highest Melting Point of Any Metal (3,422°C / 6,192°F)
– Maintains structural integrity in extreme heat (e.g., furnaces, plasma applications).
- Extreme Hardness & Wear Resistance
– Comparable to boron carbide (hardness ~7.5 Mohs), making it ideal for abrasive environments.
- High Density (19.25 g/cm³)
– Used in radiation shielding (X-rays, gamma rays) and ballistics.
- Excellent Corrosion Resistance
– Resists most acids (except strong oxidizers like nitric acid/hydrogen peroxide).
- Good Electrical & Thermal Conductivity
– Used in electrodes, heating elements, and electronic components.
- Low Thermal Expansion
– Maintains shape under rapid temperature changes (e.g., aerospace, semiconductor tools).
Common Applications of Tungsten Mesh:
- High-Temperature & Vacuum Environments
– Furnace components (sintering, heat treatment).
– Plasma & fusion reactor shielding (ITER, nuclear research).
– Rocket nozzles & thermal protection systems.
- Electronics & Semiconductors
– Heating elements (high-temp furnaces).
– Sputtering targets (thin-film deposition in chip manufacturing).
– Electron emitters & X-ray tubes.
- Filtration & Sieving in Harsh Conditions
– Molten metal filtration (aluminum, steel casting).
– Chemical processing (acid-resistant filters).
- Radiation Shielding
– Medical X-ray & gamma-ray shielding.
– Nuclear reactor components.
- Defense & Aerospace
– Missile components (heat shields).
– Armor-piercing applications (due to high density).
Comparison: Tungsten Mesh vs. Other Metal Meshes:
| Property | Tungsten Mesh | Titanium Mesh | Zirconium Mesh | Stainless Steel Mesh |
| Melting Point | 3,422°C | ~1,668°C | ~1,852°C | ~1,400°C |
| Density | 19.25 g/cm³ | 4.5 g/cm³ | 6.5 g/cm³ | 8 g/cm³ |
| Corrosion Resistance | Good (except strong oxidizers) | Excellent | Best (for acids) | Moderate |
| Biocompatibility | Poor (toxic oxides) | Excellent | Good | Moderate (Ni risk) |
| Cost | Very High | Moderate | High | Low |
Types of Tungsten Mesh:
– Pure Tungsten (W) – Highest melting point, brittle when untreated.
– Tungsten Alloys (W-Ni-Fe, W-Re) – Improved machinability & ductility.

Tungsten Wire Cloth and Crimped Woven Mesh
Advantages of Tungsten Mesh
✔ Best for ultra-high temperatures (no competition near 3,000°C+), but needs Inert gas protection.
✔ Superior radiation shielding (better than lead or steel).
✔ Extremely durable in abrasive/erosive environments.
Disadvantages:
❌ Very expensive (due to difficult processing).
❌ Very hard at room temperature when the mesh is thick, it becomes very flexible when it is thin.
❌ limited oxidation resistance, particularly at high temperatures in open environment.
