Tungsten copper alloy is an alloy composed of tungsten and copper. The copper content of the commonly used alloy is 10% to 50%. The alloy is made by powder metallurgy and has good electrical and thermal conductivity, good high temperature strength and certain plasticity. At very high temperatures, such as above 3000℃, the copper in the alloy is liquefied and evaporated, absorbing a large amount of heat and reducing the surface temperature of the material. Therefore, this type of material is also called metal sweating material.
After research and development, the preparation technology of tungsten copper alloy has made great progress, and some new processes and technologies have been promoted and applied in production.
However, in order to meet the increasingly high performance requirements and application needs under some special conditions, there are still some problems that need to be studied more deeply.
First of all, the basic research on the forming technology of tungsten copper-based alloys should be strengthened to guide the development of new technologies. Because most of the research focuses on how to prepare high-performance alloys, while ignoring the research on basic theories, this has caused a situation where theory and process technology are out of touch. For example, in the research on the development of micro-alloyed tungsten copper-based alloys, the influence of added elements on electrical conductivity, thermal conductivity and performance needs to be further studied in order to truly provide theoretical guidance for new preparation process technology.
Secondly, although some research has been done on new preparation technologies in the world, the general research is not in-depth enough, and because the required equipment is expensive and the process methods are complex, it is difficult to apply them in industrial production. Therefore, we should vigorously develop high-efficiency, low-cost, widely applicable and easy-to-master manufacturing technologies to meet the needs of technological progress and actual production. Throughout the development history of tungsten copper alloy materials, with the progress of basic research and the improvement of preparation technology, the performance of tungsten copper alloy has been greatly improved, which also provides a broader prospect for the expansion of the application field of tungsten copper alloy.
