Tungsten Copper (W-Cu) Composite Materials
 

Tungsten Copper (WCu) Alloy from BTM Group is a powder metallurgical material suffered from severe deformation with copper contents from 10 to 60 %. Tungsten Copper materials can be joined by welding or brazing with various supporting materials. 

Advantages of Tungsten Copper(WCu) Alloy:

high arc resistance combined with good electrical conductivity

high thermal conductivity
low thermal expansion
high electrical conductivity

1:Typical areas of application:
arcing contacts in high and medium voltage breakers for transmission and distribution of electrical power

carrier plates or heat sinks as passive cooling elements of electronic devices
erosion electrodes for EDM made of Sparkal
electrodes for other applications (surge protection, welding, laser applications)
