Heat Sinks

Introduction:

Tungsten Copper(WCu) 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 conductivityhigh thermal conductivitylow thermal expansionhigh electrical conductivity Typical areas of
