Description:
Tungsten copper heat sink is used for transferring heat generated in microelectronic components to prevent thermal damage.
Tungsten copper heat sink is a composite of tungsten and copper, so both the thermal advantages of copper and the very low expansion characteristics of tungsten can be adjusted to meet different requirements.
We can offer W90Cu10,W85Cu15,W80Cu20,W75Cu25,W50Cu50. And we can offer tungsten copper flanges, tungsten copper substrate, tungsten copper c-mount, tungsten copper base plate, tungsten copper carrier, tungsten copper bar, tungsten copper shim, tungsten copper pad.
The combination of these two materials results in thermal expansion characteristics similar to those of silicone carbide, aluminum oxide, and beryllium oxide, used as chips and substrates.
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
