    Description

    Molybdenum IBSC is used: for the manufacture of wire with a diameter of 200 to 500 microns, obtained by powder metallurgy and used for the manufacture of meshes in electronic products.

    Note

    Molybdenum, silica-doped. The recrystallization temperature and the tensile strength and the bending in the annealed condition is somewhat lower than that of molybdenum brand MK.

    Technological properties

    Name The value
    Particularities of production of goods For OST 11 021.004-76 wire micron size range comes in the following six groups: A. Wire having on a surface layer of the technological lubricant; B. Wire, free from technological lubricant by electrochemical etching method; B. Wire, annealed to the required mechanical properties, Wire, purified by the method of electrochemical etching and annealed to the required mechanical properties; D. Wire, annealed to the required mechanical properties. Compared to the wire group has higher strength and less elongation; E. Wire, purified by the method of electrochemical etching and annealed to the required mechanical properties. Compared with the wire of the group G has a higher coefficient "K" and a smaller elongation.
