WCu Copper Tungsten Copper Alloy plate with 10-50 wt.% Cu
Tungsten Copper :
Tungsten-Copper alloy is the composite of Tungsten and Copper,
which own the excellent performances of Tungsten and Copper, such
as heat-resistant, ablate-resistant, high-intensity, excellent
thermal and electrical conductivity. It is easy to be machined. It
is used widely in such industries as engine, electrical power,
electron, metallurgy, spaceflight and aviation.
Advantages:
1. High thermal conductivity
2. Excellent hermeticity
3. Excellent flatness, surface finish, and size control
4. Semi-finished or finished (Ni/Au plated) products available
5. Low porosity
Product Properties:
| Grade | W Content | Density g/cm3 | Coefficient of thermal Expansion ×10-6 (20℃) | Thermal conductivity W/(M·K) |
| 90WCu | 90±2% | 17.0 | 6.5 | 180 (25℃) /176 (100℃) |
| 85WCu | 85±2% | 16.4 | 7.2 | 190 (25℃) / 183 (100℃) |
| 80WCu | 80±2% | 15.65 | 8.3 | 200 (25℃) / 197 (100℃) |
| 75WCu | 75±2% | 14.9 | 9.0 | 230 (25℃) / 220 (100℃) |
| 50WCu | 50±2% | 12.2 | 12.5 | 340 (25℃) / 310 (100℃) |
Application:
They are extensively used as thermal mounting plates, chip carriers, tungsten copper flanges, and frames for RF, light emitting diodes and detectors, laser diode packages like pulse, single emitter, bars and complex carriers for optoelectronics amplifiers, receivers, transmitters, tunable lasers, etc.
