Cleaned Molybdenum Wire

Cleaned molybdenum wire is a surface clean, no graphite layer and molybdenum oxide layer molybdenum wire, which has a good high strength, conductivity, cutting speed, long life and other good properties. Cleaned molybdenum wire is usually applied in line cutting field, it usually as vacuum devices, heating elements, refractory matter of high temperature furnace and the parts for electric light source production. In addition, the cleaned molybdenum wire can also be used as a spray molybdenum wire, applied to the wear parts of the car, improving its mechanical wear.

White molybdenum wire also called clean white molybdenum wire, using electrolytic cleaning or hydrogen sintering method to clean graphite coating on molybdenum wire surface and to make the surface bright and glossy. Electrolytic cleaning cleaned molybdenum wire method: this is a cleaning method which uses conducting medium to apply voltage on molybdenum wire and to clean molybdenum wire. And the molybdenum wire will as an electrode and immerse in electrolyte. Hydrogen sintering clean white molybdenum wire method: This method is mainly cleaning metal impurities on the surface of molybdenum wire. Firstly, putting molybdenum wire in vacuum furnace, heating vacuum furnace above 1400 ℃, repeated pass hydrogen into vacuum furnace to make the amount of hydrogen in the furnace reaches 500-10,000 microns, then remove the reaction products which produces by impurities on cleaned molybdenum wire surface and hydrogen.

Cleaned molybdenum wire applications and its performance has a certain relationship between the degree of processing, for example, un-annealed cleaned molybdenum wire and annealed molybdenum wire can as rods, hooks, mandrel and the electrodes applied to different areas, but the performances of them are different, for example, annealed cleaned molybdenum wire elongation is ≤8%; straightness is ≤20 / 200, tensile strength is 1200-2200MPa. On the other hand, un-annealed cleaned molybdenum wire elongation is ≥10%; straightness is ≤ 20/200; tensile strength is 700-1500MPa. The user can select different processing levels’ white molybdenum wire according to application.
