molybdenum disk copper and copper alloy

W is tungsten, copper and copper alloy, tungsten-copper alloy used copper content of 10% to 50%. Tungsten copper alloy powder metallurgy method of preparation, has good electrical and thermal conductivity, good high temperature tungsten sheet‍ strength and a certain plasticity. At very high temperatures, such as above 3000 ℃, tungsten-copper alloy of copper is liquefied tungsten electrode absorbs heat and reduce the material surface temperature. molybdenum disk‍ So this kind of material is also called metal sweating materials. Tungsten copper alloy has relatively wide range of uses, mainly used to manufacture high-voltage electrical arc erosion resistant switch contacts and the rocket nozzle throat, rudder and other high temperature components, also used as EDM electrodes, tungsten weights‍ high temperature mold processing as well as other requirements of thermal conductivity properties and high temperature use of the occasion.
