W–Cu System: Synthesis, Modification, and Applications

  • Published:
Powder Metallurgy and Metal Ceramics Aims and scope

W–Cu composites, as a traditional material, have attracted tremendous research interest in fields such as electric engineering, electronic information, aerospace, weapons, etc., owing to their excellent properties. This critical review presents and discusses the current development of W–Cu composites. After introduction of the synthesis methods for W–Cu composites, including the conventional and modern preparation approaches, we focus on the description of the improvement of mechanical properties and arc-erosion properties by modification techniques. Finally, the advantages of W–Cu composites in applications such as electrical contacts, electronic packaging materials, and heat sinks, as well as military materials, are described.
