MoCu CARRIER / HEAT SINK FOR HERMETIC PACKAGES ELECTRONICS WITH HIGH COEFFICIENT OF THERMAL EXPANSION
Description:
Molybdenum copper alloy is a composite material of molybdenum and copper which has adjustable coefficient of thermal expansion and thermal conductivity. But the density of molybdenum copper is much smaller than tungsten copper.Therefore, molybdenum copper alloy is more suitable for aerospace and other fields.
Advantages:
1. This molybdenum copper carrier/heat sink feature high thermal conductivity and excellent hermeticity.
2. Molybdenum copper carriers are 40% lighter than comparable tungsten copper composite.
Product Properties:
| Grade | Mo Content | Density g/cm3 | Coefficient of thermal Expansion ×10-6 (20℃) | Thermal conductivity W/(M·K) |
| 85MoCu | 85±2% | 10.0 | 7 | 160(25℃)/156(100℃) |
| 70MoCu | 70±2% | 9.8 | 7 | 200(25℃)/196(100℃) |
| 60MoCu | 60±2% | 9.66 | 7.5 | 222(25℃)/217(100℃) |
| 50MoCu | 50±2% | 9.5 | 10.2 | 250(25℃)/220(100℃) |
Application:
This composite are widely used in applications such as microwave carriers, ceramic substrate carriers, laser diode mounts, optical packages, power packages, butterfly packages and crystal carriers for solid state lasers, etc.
