molybdenum copper heat sink
Release time:
2020-05-25
Source:
Mo-Cu composite is similar with Tungsten-Copper composite, its thermal expansion coefficient and thermal conductivity can be adjusted to match many different materials, it has lower density,which makes it a great alternative to tungsten copper for weight sensitive applications.
Features:
High thermal conductivity due to no sintering additives was used;
Excellent hermeticity;
Relatively small density;
Stampable sheets available (Mo content not more than 75wt%);
Semi-finished or finished (Ni/Au/Ag plated) parts available;
Physical Properties:
| Material | Wt% moly content | g/m³ Density at 20℃ | Thermal conductivity at 25℃ | Coefficient of thermal expansion at 20℃ |
| Mo85Cu15 | 85±2 | 10 | 195 | 7 |
| Mo80Cu20 | 80±2 | 9.9 | 204 | 7 |
| Mo70Cu30 | 70±2 | 9.8 | 208 | 7.3 |
| Mo60Cu40 | 60±2 | 9.66 | 223 | 8.4 |
| Mo50Cu50 | 50±2 | 9.5 | 230 | 10.2 |
Application:
These composite are widely used in applications such as Optoelectronics Packages, Microwave Packages, C Packages, Laser Sub-mounts, etc.
