Product Description
TUNGSTEN COPPER COMPOSITE (WCu)
Product 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.
Our Tungsten Copper Composite Features:
No Fe, Co, Ni, Mn and other elements added as the sintering
activator, to maintain a high thermal conductivity
Excellent hermeticity
Can provide semi-finished or finished (Ni/Au plated) products
Precision machining and excellent dimensional control, surface
finish and flatness
With close technical support including product design, custom
manufacturing, testing and post sale supports.
Tungsten Copper Sheet picture:
Tungsten copper (Cu-W)Alloy is the composite of tungsten and copper
which own he excellent performance of tungsten and copper. It is
used widely in such industries as engine, electric power, electron,
metallurgy, spaceflight and aviation.
