Copper Tungsten (WCu/CuW) / Molybdenum Copper (MoCu/CuMo) / Copper Molybdenum Electronic Packaging Materials
Description:
Copper Tungsten are composites of tungsten and copper. By adjusting the content of tungsten, we can have its coefficient of thermal expansion (CTE) designed to match those of materials such as ceramics (Al2O3, BeO), semiconductors (Si), and metals (Kovar), etc.
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. High thermal conductivity
2. Excellent hermeticity
3. Stampable sheets available
4. Semi-finished or finished (Ni/Au/Ag/NiPd/Au plated) products available
5. Low void
