    Product Detail

    Product Tags

    Tungsten Tube

    Small-diameter tungsten tubes are generally processed by forged tungsten rods, and their density can reach 19.3g/cm³. Large-diameter tungsten tubes are usually manufactured by sintering technology (usually with a diameter of φ80mm or more), and their density is generally greater than 18.3g/cm³.

    We provide pure tungsten tubes, which are used in various high-temperature industries. Thanks to years of production experience, our tungsten tubes have the advantages of high-temperature resistance, no pollution, corrosion resistance, and high-temperature strength.
