2. Property Brief Introduction
W-Cu 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, these features make the application of
this composite with great convenience.
1) high melting point, high strength,
2) smooth and clean surface,
3) good conductions, small linear expansion coefficient and good
heat-resistance
