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…

According to China Tungsten Online, the tungsten market in China exhibited an overall downward trend in February 2025, primarily attributed to the implementation of export control policies on tungsten-related items, price reductions in long-term contracts by major tungsten enterprises, and persistently weak downstream demand. Among them, the price of black tungsten concentrate dropped by approximately 2.05%, ammonium paratungstate price fell by about 1.40%, tungsten powder price decreased by around 0.94%, carbide tungsten powder price declined by roughly 0.95%, while the…
