Most tungsten crucible is produced by sintering pure tungsten. The reason to use pure tungsten as raw material is to prevent other metals melting in the tungsten crucible from mingling impurities. Because tungsten crucible has the advantages of high-density, high strength, low resistivity, low thermal expansion, erosion-resistance, tungsten crucible is widely used in various industries. According to the required diameter, thickness, tilt angle, we can produce a various shapes and sizes of tungsten crucible to meet your need.
