In the metal industry, people often refer to white molybdenum wire as clean molybdenum wire. It uses electrolytic cleaning or hydrogen sintering cleaning method to clean the surface of molybdenum wire and remove the graphite coating on the surface. After cleaning, the molybdenum wire will be bright. glossy surface. The diameter of the clean molybdenum wire is 0.05~3mm. The surface condition of the white molybdenum wire should be bright and free of oxidation, rust, or spots. Its features: are high strength, good electrical conductivity, bright and shiny surface, fast cutting speed, long service life, etc.

White molybdenum wire is usually used for wire cutting, production of electric light source parts, electric vacuum devices, production of heating elements, and refractory materials for high-temperature furnaces. In addition, it is also used to spray molybdenum wire, the wear-resistant parts of automobiles to improve its mechanical wear resistance. Black molybdenum wire is a graphite coating on the molybdenum wire, and its surface color is black. It is always curled or straight, so it is produced by annealing.
Black molybdenum wire mainly refers to a consumable made of precious metals such as molybdenum, which is continuously moved with a high-voltage electric field to cut the workpiece during wire cutting. Also called electrodes), they can perform pulse spark discharge erosion on workpieces and cut metal forming. It has many other uses. High-quality high-temperature molybdenum raw materials are processed into filaments by advanced hot-cold drawing combined technology, which is used as an electrode for wire cutting machine tools to process workpieces. Baoji Yusheng Company's molybdenum wire surface state forming process is drawing, forging, and polishing.
Properties and functions of black molybdenum wire: It has excellent electrical conductivity, high-temperature resistance, high melting point, high oxidation, and erosion resistance. In general, the white molybdenum wire and black molybdenum wire we produce are more or less different in surface, raw material, size, diameter, characteristics, performance, and application.
Baoji Yusheng Company can mass-produce the two molybdenum wires mentioned above: white molybdenum wire and black molybdenum wire. You can directly contact us for product consultation.
