Tungsten Copper (WCu) is a composite alloy consisting of tungsten and copper, commonly with a copper content ranging from 10% to 50%. Produced using advanced powder metallurgy, this alloy boasts:
Outstanding thermal and electrical conductivity
Exceptional high-temperature strength
Reliable plasticity and durability
When exposed to extreme temperatures exceeding 3000°C, the copper in the alloy vaporizes, effectively absorbing heat and lowering the material's surface temperature. This unique feature has earned it the name: Metal Sweating Material.

Here’s what makes Tungsten Copper your ultimate choice for extreme applications:
High-Temperature Resistance: Withstands temperatures up to 2000°C and high mechanical stress.
Durability: Features high hardness, excellent anti-wear properties, and resistance to adhesion.
Low Loss and High Precision: Provides smooth and precise surfaces during electrical discharge machining (EDM), with minimal material loss.
| Material Composition (wt%) | W-10Cu | W-15Cu | W-20Cu | W-25Cu | W-30Cu |
|---|---|---|---|---|---|
| Density (g/cm³) | 17.1 | 16.4 | 15.5 | 14.8 | 14.2 |
| Thermal Conductivity (W/m·K) | 191 | 198 | 221 | 235 | 247 |
| Thermal Expansion Coefficient (×10⁻⁶ K) | 6.3 | 7.1 | 7.6 | 8.5 | 9.0 |
Tungsten Copper’s versatility makes it a preferred choice for a wide range of demanding applications, including:
