Tungsten-copper alloy is widely used in the fields of national defense, aerospace, electronic information and machining, and plays an important role in the national economy. Tungsten-copper alloy has high density, good thermal and electrical conductivity, and low thermal expansion coefficient. Therefore, in large-scale integrated circuits and high-power microwave devices, tungsten-copper alloy sheet as electronic packaging substrate, connector, heat sink and microelectronic shell materials can effectively reduce the stress problems caused by insufficient heat dissipation and differences in thermal expansion coefficient, and extend the service life of electronic components. It has broad application prospect.

Has been widely used in medium and high voltage electrical appliances, communications, aviation, aerospace and military and other fields. Alloy powder is widely used in the field of microelectronics information technology and aerospace, such as electronic packaging, heat sink materials and rocket nozzle, aircraft throat lining; The coated tungsten powder with large particle size is widely used in military industry, for example, it can be used to prepare drug-shaped cover, because the coarse tungsten powder with appropriate particle size has higher density, which can greatly improve the armor-breaking power of the bomb.
