GMHI. M2, GMHYM. The first 3 is rare earth high temperature lanthanum and yttrium molybdenum.
Rare earth elements are not used as impurity meters.
Dimensional Tolerance Standard for Molybdenum Wire Production: National Standard GB/T4182-2003 \"Molybdenum Wire\"
Specification: 0.02mm - 12.0mm
Other uses: hook, core wire, grid side rod support, lead wire, etc.
At present, the domestic molybdenum wire manufacturers are: Shandong Guangming, Nanjing Diamond, Huaming and so on.
The characteristics of molybdenum wire as electrode wire:
(1) Super high tensile strength;
(2) High surface finish, good stability and high cutting accuracy;
(3) Low elongation and small tightness;
(4) Large curvature, uniform diameter, not easy to break, long life;
_High frequency power can be increased and roughing efficiency can be improved.
_Accurate measurement, vacuum packaging, prevent oxidative mildew, long-term preservation.
