    Tungsten Tube

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

    We offer pure tungsten tubes for use in various high-temperature industries. With many years of production experience, our tungsten tubes have the advantages of high-temperature resistance, no pollution, corrosion resistance, and high-temperature strength.
