Tungsten has the highest melting point of all metals as well as a remarkably high modulus of elasticity. Thanks to its outstanding thermal properties, tungsten can easily withstand even the most intense heat. Tungsten Crucible Chemical composition: Tungsten >99.95% ( percentage by weight) Density: >18.3G/CC Specification: Diameter range: Dia100----Dia400mm Height range: H200----H500mm Surface finish: < Ra3.2 shining furnace Working temperature: 1800 ~ 2600 In Vacuum or deoxidize atmosphere Produce Method: Powder Metallurgy Main applications Tungsten crucible is mainly used for rare earth, sapphire single crystal growth furnace, quartz glass, metal extracting, metallurgical industry, machinery processing, glass and ceramic industries, etc. SMT's advantage in tungsten crucible: 1)Large size, high purity, high density, Smooth furnace 2)Long history of supplying the tungsten crucible for Single crystal growth furnace and silicon produce furnace 3)Competitive price & professional service.
