As a typical molybdenum product, molybdenum wire is a filament made by forging and drawing molybdenum bars or rods. It is a kind of molybdenum wire that continuously moves with a high-voltage electric field to cut the workpiece during wire cutting. A thin metal wire made of other chemical elements, called Molybdenum wire in English, contains as much as 99.90% molybdenum, and its diameter is generally between 0.02-12.00mm. It is worth mentioning that in order to further improve the performance of pure molybdenum wire and expand its application range, manufacturers often add elements such as lanthanum and yttrium during its manufacture.
From the perspective of physical and chemical properties, molybdenum wire is generally silver gray or black in color (surface covered with graphite), has a higher melting point, higher density, higher tensile strength, lower resistivity, and smaller thermal expansion. coefficient, small elongation, good high temperature resistance, acid and alkali resistance and other characteristics. It should be noted that when heated in air, it will react with oxygen; the overall performance of doped molybdenum wire is generally better than that of pure molybdenum wire.
From the perspective of production technology, pure molybdenum wire is a product that uses a hot and cold drawing process to process high-temperature molybdenum raw materials into filaments. The production method of doped molybdenum wire is a solid-liquid doping method, that is, adding an appropriate amount of solid solution metal elements and rare earth oxides to solid molybdenum dioxide, then mixing evenly, and finally performing hydrogen reduction and isostatic pressing. , sintering, rotary hammer beating, hot drawing, annealing and cold drawing.
From the perspective of use, molybdenum wire is generally used for wire-wound core wires, brackets, lead wires, tube reeds, grids, heating elements, molybdenum foil strips, wire cutting high-temperature components, automobile parts spraying, etc.
From the perspective of storage methods, molybdenum wire should generally be placed in a ventilated and cool place with low humidity and temperature to avoid oxidation. In addition, poor verticality may occur if left for more than 6 months.
