Application
Sintering tungsten rod is mainly used as the raw material 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 supports in high-temperature furnace.
