white molybdenum wire
White molybdenum wire is also called clean molybdenum wire. It uses electrolytic cleaning or hydrogen sintering cleaning method to clean the surface of molybdenum wire to remove the graphite coating on the surface. After cleaning, the surface will be bright and shiny. The diameter of the cleaning molybdenum wire ranges from 0.05 to 3mm.
Its surface condition should be bright and free of oxidation, rust or spots. Its characteristics: high strength, good electrical conductivity, bright and shiny surface, fast cutting speed, long service life, etc.
It 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 as spray molybdenum wire and wear-resistant parts of automobiles to improve their mechanical wear resistance.
Black molybdenum wire
Black molybdenum wire is made of molybdenum wire coated with graphite coating, and its surface color is black. It is always curved or straight. In addition, it is produced through annealing.
It mainly refers to a consumable made of precious metals such as molybdenum that continuously moves with a high-voltage electric field to cut the workpiece during wire cutting processing. That is, the thin metal wire that continuously moves when the wire cutting machine processes the workpiece is called electrode wire (also called electrode wire). Electrode), which can perform pulse spark discharge erosion on the workpiece and cut metal into shape. It has many other uses. Advanced hot and cold drawing technology is used to process high-quality high-temperature molybdenum raw materials into filaments, which are used as an electrode on wire-cutting machine tools to process workpieces. Molybdenum wire surface condition forming process: drawing, forging, polishing.
Its performance and function: It has excellent electrical conductivity, high temperature resistance, high melting point, high oxidation and erosion resistance, etc.
In general, there are many differences between white molybdenum wire and black molybdenum wire in terms of surface, raw materials, size, diameter, characteristics, performance and application.
