CuW50 is an alloy composed of 50% copper and 50% tungsten. It combines the advantages of both metals, offering the following characteristics:
High melting point: Given that the melting points of tungsten and copper are 3410°C and 1080°C respectively, CuW50 possesses a high melting point, making it suitable for high-temperature environments.
High density: With tungsten’s density at 19.25 g/cm³ and copper’s at 8.92 g/cm³, CuW50 has a density of approximately 11.85 g/cm³.
Good electrical and thermal conductivity: Copper’s superior conductivity properties ensure that CuW50 performs well in conducting both electricity and heat.
High strength and arc erosion resistance: The high hardness and melting point of tungsten impart high strength and resistance to arc erosion to the alloy.
Transpiration cooling effect: At high temperatures, the copper component liquefies and evaporates, absorbing significant heat and lowering the material’s surface temperature; this characteristic provides effective cooling in high-temperature environments.
Applications for CuW50 include:
High-voltage electrical switch contacts: Its resistance to arc erosion and high electrical conductivity make it suitable for contacts in high-voltage switches.
Rocket nozzle throat inserts and tail fins: Capable of withstanding high temperatures and stresses, it is suitable for high-temperature components such as rocket nozzle throat inserts and tail fins.
Electrodes for electrical machining: Used as electrode and mold material in processes such as electrical discharge machining (EDM), resistance welding, and electric riveting.
High-temperature molds: Suitable for applications requiring both thermal/electrical conductivity and high-temperature performance. In summary, Tungsten-Copper 50 is a high-performance alloy widely used in applications requiring high-temperature resistance, as well as high electrical and thermal conductivity.
