Ultrathin tungsten alloy bar can be formed into a tungsten boat after being pressed at high temperature. It is widely used in evaporator, imaging lens, the heating container, spray paint of electron beam, household appliances (shell), mobile phones, toys, and various accessories, such as vacuum coating industry and sintering furnace for sintering or vacuum annealing in ship industry.
In an ideal (vacuum, dry) state, wire is connected and energized at both ends of the tungsten boat. The low-melting metal is placed in the center depression. When the temperature rises below 2000 degrees, the metal will evaporate into gas and be plated on the surface of the workpiece above. Chinatungsten Online adopts overpressure automatic pressure relief extrusion equipment, so various models and specifications of ultrathin tungsten alloy bar can be produced.
