Tungsten-Copper high performance composites are fabricated
from carefully controlled porous tungsten that is vacuum
infiltrated with molten copper. This results in a W/Cu
composite that has high conductivity and a matched low
thermal expansion for heat sinks.
Tungsten copper heat sink is a composite of tungsten and copper. By controlling the
content of tungsten, we can design its coefficient of
thermal expansion (CTE), matching that of the materials,
such as Ceramics (Al2O3, BeO), Semiconductors (Si), Kovar,
etc.
