Molybdenum wire (white molybdenum wire)

  1, classified according to the performance and grades into pure molybdenum wire, Molybdenum tube wire lanthanum, yttrium molybdenum wire, wire cutting molybdenum wire dedicated four categories.
2, grade and by the use of different chemical composition is divided into G MPM. A 1, GMH [. M. A 2, GMHYM. One three three grades.
3, size 0 03-5 5mm
4, use
   Pure molybdenum wire GMPM. A wire around a core wire is used, brackets, pinout, heating elements, molybdenum foil, wire cutting, auto parts spraying.
   Lanthanum molybdenum wire GMHI-M. A two wire around the core wire for glass sealing parts, molybdenum foil, furnace heating materials, high temperature components such as wire cutting.
   Yttrium molybdenum wire GMHYM. A 3 for the bracket, Lead, reed valves, gate, furnace heating materials, high temperature components.
   Dedicated wire cutting molybdenum wire GMPM. A 1, GMHI. M. A 2 for a variety of non-ferrous metals, steel and magnetic cutting. High strength, good discharge performance, surface finish, cutting speed an Shaanxi, long life and other characteristics. Key performance indicators are as follows: Size range um minimum tensile strength Mpa Elongation%

6, dimensional tolerances
Reference to national standards GB/T4182-2003 "molybdenum wire" the relevant technical requirements of execution.
7, packaging
Diameter of less than 0 4mm molybdenum wire wound dry dry bakelite or plastic shaft surface with a glossy seal affixed after the tray or plastic box; big 0 4 mm diameter molybdenum wire wound into a roll-hours, with a moisture paper or plastic strip bandage tightly.
8, storage
Molybdenum wire should be stored in a dry, relative humidity less than 65% acid-free atmosphere, transit time moisture
