Follow on Google News | Machining processes of tungsten ⅡAll the properties make tungsten metal hard to be machined, here we will introduce the machining process for tungsten tube & crucible, Plate, Sheet & Foil.
As tungsten's relatively poor machability, the process & machine selection is very important. It might be crack in the process seriously, or not able to reach the tolerance. The raw material and annealing process counts a lot too. After sintering, the tungsten blank will be forged, to make a higher density and better mechanical properties. Process of tungsten plate (https://www.edge- For the thinner sheets & foil, they are rolled from thick sheets. When down to a certain thickness, let's say 1mm, the hot rolling process will be changed to cold rolling. It still needs to be annealed even for cold tolling. Process of tungsten tube: Small tubes (roughly with diameter <100mm) are drilled from rods, larger tubes is made by sintering directly. Will need to make mold first if the tubes are large, you can choose a more economical way to make the tube with a critical outer diameter. Drilling from rods will waste some materials, while sintering needs a tool. The process of tungsten crucible (https://www.edge- Another way to make tube & crucible is welding, riveting. This is used for parts work short time and has not strictly required for leaking issues, this kind of tubes and crucibles are cheaper.
