Copper Tungsten(Cu-W) Rod

Copper tungsten is a remarkable composite material that combines the unique properties of copper and tungsten. This material is widely used in various industries due to its excellent thermal and electrical conductivity, as well as its high resistance to wear and corrosion. Additionally, copper tungsten possesses a low coefficient of thermal expansion, making it an ideal choice for applications that require dimensional stability under varying temperatures.
One of the most common forms of copper tungsten is the rod, which is manufactured through a process called infiltration. During this process, tungsten powder is compacted and sintered to create a porous structure, which is then infiltrated with molten copper. The resulting copper tungsten rod exhibits a homogeneous distribution of tungsten particles within the copper matrix. Moreover, the ratio of copper to tungsten can be adjusted to achieve specific properties tailored to different applications.
As copper and tungsten shall not really melt together, Cu-W is produced by powder metallurgy. Due to the high electric conductivity and relatively high max. working temperature of this material, copper-Tungsten rod is usually used in electric component, such as electrodes.
