Copper tungsten alloy rod is a composite material that combines the high melting point and hardness of tungsten with the excellent electrical and thermal conductivity of copper. Through advanced powder metallurgy technology, tungsten and copper are combined in a unique microstructure, making tungsten copper alloy rod not only have the high temperature resistance and wear resistance of tungsten, but also retain the excellent electrical and thermal conductivity of copper, and perform excellently in many high demand application fields.
The main characteristics of tungsten copper alloy rods include:
Excellent conductivity: Copper is one of the metals with excellent conductivity, and tungsten copper alloy inherits the excellent conductivity of copper, making it have lower resistance when energized.
Excellent Thermal Conductivity: Copper has excellent thermal conductivity, and the thermal conductivity of tungsten-copper alloy makes it an efficient thermal management material.
High melting point and high hardness: The melting point of tungsten is as high as 3422 ℃, and tungsten copper alloy inherits the high melting point and hardness of tungsten, making it highly stable in high temperature environments.
Low Coefficient of Thermal Expansion: Tungsten has a low coefficient of thermal expansion, which, when combined with copper, results in an overall low coefficient of thermal expansion, making it less susceptible to deformation and cracking in high and low temperature cycling.
Good resistance to arc erosion: Tungsten endows alloys with excellent resistance to arc erosion, giving them a longer lifespan in electrical contact applications.
Machinability: Tungsten-copper alloys can be machined, EDM’d, etc. to desired shapes.
Customizability: The ratio of tungsten to copper can be adjusted according to application requirements to achieve optimum performance.
