4.Application
Sintering Tungsten rod, as the material, is mainly used in pulling Tungsten wire and Forging Tungsten Rod. As Tungsten possesses the feature of dyslectic point, forging Tungsten rod with high-purity, high-density and excellent high-temperature proof of creep deformation is widely applied for tungsten crucible's supports in the sapphire growth furnace, electrodes, heating elements, connections and support rods in high-temperature furnace.
