Cleaned tungsten wire is produced through processes such as forging, drawing, and heat treatment.
The processing of cleaned tungsten wire presents certain challenges due to its high hardness, room-temperature brittleness, and high-temperature ductility. Processing requires strict control of temperature, atmosphere, and process parameters, typically employing techniques such as high-temperature wire drawing, annealing, and precision dies. Compared to doped tungsten wire, cleaned tungsten wire has slightly inferior processing properties, particularly in fine wire fabrication and high-temperature strength retention. However, its high purity makes it suitable for specific applications, such as electro-vacuum devices.
Cleaned tungsten wire can be formed into high-precision fine wires, making it applicable in precision fields.
