Tungsten-copper Rods for Microelectronic Materials

Copper tungsten is a metal matrix composite consisting of the low thermal expansion of tungsten fused with the superior thermal and electrical conductivity of copper. This composite material is highly machinable and can be tailored to meet numerous specifications through material composition design. Materials manufactured out of tungsten copper can meet a plethora of thermal expansion coefficient matching requirements with ceramics, Kovar, and various semiconductor materials. Therefore, they are extensively utilized for the packaging and heat dissipation in radio frequency microwave devices, power semiconductor devices, and optical communication devices.  Copper tungsten is extremely crucial in the field of electronics due to its exceptional physical and electrical properties. The high strength, amazing electrical and thermal conductivity, and low thermal expansion coefficient make it the optimal choice for embedding the design of engineered electronics.  It is commonly found in a wide range of power electronic devices, such as rectifiers, thyristors, power modules, and high-power applications like laser diodes and microwave tubes. In addition, copper tungsten is instrumental in microelectronic devices like computer CPUs and DSP chips. In advanced fields such as the aerospace industry, microwave communication, automatic control, and power conversion, the value of tungsten copper composite materials is profound. Currently, it is primarily used as a heat sink for high-power microwave tubes, high-power laser diodes, and certain high-power integrated circuit modules, ensuring that these critical components operate stably in high-temperature environments.
