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

WCu tungsten copper alloy application and performance:
1.  Arcing contacts and vaccum contacts in high and medium voltage breakers or vaccum interruptors;
2.  Electrodes in electric spark erosion cutting machines;
3.  Electrodes for resistance welding;used 
where the combination of high heat resistance, high electrical
4. Some of the applications are in electric resistance welding, as electrical contacts, and as heat sinks.
5. As contact material the alloy is resistant to erosion by electric arc. WCu alloys are also used in electrodes for electrical discharge machining and electrochemical machining.


Advantages of Copper Tungsten Plates:
1. Better heat resistant; 
2. Better ablate-resistant; 
3. High intensity
4. High density; 
5. Excellent thermal and electrical conductivity; 
6. Easy to be machined.
