钨铜（W-Cu）复合材料作为一种传统的耐火材料，由于其优异的性能，在制造电触头和电极、重型电子触头、焊接和电锻模具、散热器、封装材料、耐电弧电极和热管理器件等方面有着广阔的应用前景。本文综述了钨铜复合材料的研究进展。首先介绍了钨铜复合材料的制备方法，包括传统的制备方法和现代的制备方法。在此基础上，重点介绍了改性技术对材料力学性能和耐电弧烧蚀性能的改善。最后，分别介绍了钨铜复合材料在电触头、电子封装材料、散热器以及军事材料等方面的应用优势。
Tungsten copper (W-Cu) composites, as a traditional refractory material, are promising materials for manufacture of electrical contacts and electrodes, heavy duty electronic contacts, welding and electro-forging dies, heat sinks, packaging material, arcing resistance electrodes and thermal management devices owing to their excellent properties. This critical review presents and discusses the current progress of W-Cu composites. Starting with an introduction of the synthesis methods for W-Cu composites, including the conventional and modern preparation approaches. After that 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, respectively.
