Tungsten crucible
Because tungsten has a melting point of 3410°C, high purity, high density, no internal cracks, precise dimensions, and smooth inner and outer walls, it is widely used in sapphire single crystal growth furnaces, quartz glass melting furnaces, rare earth smelting furnaces and other industrial furnaces The working temperature environment of the core container inside is generally above 2200℃. The tungsten crucible plays a key role in the success rate of seeding, the quality control of crystal pulling, the potting and the service life of sapphire crystal growth.
Application: Mainly used in metallurgical industry, mechanical processing, glass and ceramic industry and other fields

Tungsten plates, tungsten sheets
Tungsten plates, tungsten sheets and tungsten targets are usually produced into compacts by powder metallurgy and then heated and forged at high temperatures. Depending on the processing technology and surface treatment, they appear gray-black or bright silver. After rolling with a deformation of more than 60%, the density of the tungsten plate is basically close to the theoretical density of tungsten. Therefore, it has high strength, uniform internal structure and excellent high temperature creep resistance.
High purity tungsten rod|tungsten rod|tungsten rod
Tungsten rods, tungsten bars and tungsten electrodes are finished products of pure tungsten metal processed by high temperature and high pressure. The appearance is black or bright silver depending on the processing technology. Tungsten rods have the characteristics of high melting point, low thermal expansion coefficient and good thermal conductivity, and are widely used in traditional industry and military.
