Cu-W semiconductor substrate tungsten copper heat sink package material for integrated circuit

Description:

CuW heat sink material is a composite of tungsten and copper, with both tungsten low expansion characteristics, but also has copper of high thermal conductivity properties, and the tungsten and copper in the thermal expansion coefficient and thermal conductivity can be adjusted with the W-Cu composition, also the composite can be machined to various shape.

Advantages:

High thermal conductivity

Excellent hermeticity

Excellent flatness, surface finish, and size control

Semi-finished or finished (Ni/Au plated) products available

Product Properties:

Grade	W Content	Density g/cm³	Coefficient of thermal Expansion ×10^-6(20℃)	Thermal conductivity W/(M·K)
