Tungsten-copper parts are made from high-performance tungsten-copper alloy, combining tungsten’s high melting point and strength with copper’s excellent electrical and thermal conductivity. With a moderate density, high thermal conductivity, and a low thermal expansion coefficient, these parts are ideal for extreme working environments involving high temperatures, high currents, and strong impacts. Widely used in aerospace, electronic packaging, electrical discharge machining (EDM), high-voltage electrical contacts, and heat sink materials, tungsten-copper parts ensure stable electrical conductivity and heat dissipation. They can be…

Silver tungsten rod is a high-performance metal composite material composed of 60% tungsten and 40% silver. It combines tungsten’s high melting point and wear resistance with silver’s excellent electrical and thermal conductivity. This material is widely used in electrical contact materials, electrodes, electrical discharge machining (EDM), and high-temperature conductive components. With excellent arc erosion resistance and low contact resistance, silver tungsten rod ensures stability in high-temperature and high-current environments. Additionally, it offers superior wear resistance and mechanical strength.

Tungsten-copper heat sinks are composite materials that combine high thermal conductivity with a low coefficient of thermal expansion. They are widely used in high-power electronic devices, RF and microwave components, IGBT modules, and aerospace electronic packaging. Composed primarily of high-density tungsten and highly conductive copper, these heat sinks ensure excellent heat dissipation while maintaining good mechanical strength and high-temperature stability. With high thermal conductivity and a low thermal expansion coefficient, tungsten-copper heat sinks effectively prevent thermal stress mismatch, enhancing the…
