Comparison of white molybdenum wire and black molybdenum wire

Transfer from China Molybdenum Industry News Net

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, it has a bright and shiny surface. The diameter of the clean molybdenum wire ranges from 0.05 to 3 mm.

Its surface condition should be bright, without oxidation, rust or spots, etc. 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 refractory materials for heating elements and high-temperature furnaces. In addition, it is also used for spraying molybdenum wire, wear-resistant parts of automobiles to improve its mechanical wear resistance. White molybdenum wire picture

Black molybdenum wire

Black molybdenum wire is a graphite coating coated on the outside of the molybdenum wire, and its surface color is black. It is always curled or straight. In addition, so it is produced after annealing treatment.

It mainly refers to a consumable made of precious metals such as molybdenum with a high-voltage electric field continuously moving during the wire cutting process to cut the workpiece. That is, the thin metal wire that continuously moves when the wire cutting machine processes the workpiece is called the electrode wire (also called Electrode), it can perform pulse spark discharge erosion and cutting metal forming on the workpiece. It also has many other uses. The high-quality high-temperature molybdenum material is processed into filaments by the advanced hot-cold drawing combination process, which is used as an electrode on the wire cutting machine to process the workpiece. Molybdenum wire surface condition molding process: drawing, forging, polishing.

Its performance and function: It has excellent electrical conductivity, high temperature resistance, high melting point, high oxidation and erosion resistance.

In general, there are many differences between white molybdenum wire and black molybdenum wire in surface, raw material, size, diameter, characteristics, performance and application.
