Tungsten crucible (English name: Tungsten Crucibles) is one of the tungsten metal products. It is mainly divided into sintering molding (used in powder metallurgy technology), stamping molding, spinning molding, etc. It is turned from tungsten rods (generally smaller in size) and welded into various shapes. It is made of pure tungsten plates, tungsten sheets and pure tungsten rods processed by corresponding processes.

Craftsmanship:
Tungsten crucibles have different production processes according to different dimensions and usage conditions. Common crucible shapes include round, square, long, V-shaped, etc. The production processes include sintering forming, welding forming, stamping forming, and spinning forming, among which sintering forming products are the most widely used. For micro and small tungsten crucibles, forged tungsten rods can be turned or stamped. The tungsten plate welding process uses rolled tungsten plates to be hot-bent and finally fixed by welding. Spin forming is suitable for producing thin-walled tungsten crucibles and has high process requirements.
Tungsten crucible is also a typical product of refractory metal tungsten. It is a product using metal tungsten powder as the main raw material. It is a high temperature resistant container. Its English name is tungsten crucible. Tungsten content is generally higher than 99.95%. Its shape is generally cylindrical, with a diameter between 10mm and 500mm, a height between 10mm and 750mm, and a wall thickness between 8mm and 20mm.
