Molybdenum wire
1. According to performance and the grades, molybdenum wires are classified into four major categories: pure molybdenum wire, la molybdenum wire, yttrium-molybdenum wire, dedicated line cutting molybdenum wire.
2. According to the different chemical composition and use ,grades are classified into 3 :G MPM．一1、GMH[．M．一2、GMHYM．一3.
3. Specification: 0 03-5 5mm
4. Use
Pure molybdenum wire G MPM．一1 is for filament-winding wires, bracket, pin-out, heating elements, molybdenum foil, wire cutting, spraying and other vehicle parts.
La molybdenum wire GMHI-M. 一2 can be used as wires around core wires for glass seals, molybdenum foil, furnace heating materials and high temperature components such as wire cutting.
Yttrium molybdenum wire GMHYM.一 3 can be used for support, lead, tube spring, gate, furnace heating materials and high temperature components.
Dedicated line cutting molybdenum wire GMPM．一1，GMHI．M．一2 can be used for various non-ferrous metals, steel and cutting magnetic material. Its features are high strength, good discharge performance, high surface finish, cutting speed of Shaanxi and long service life.
Key performance indicators are as follows: size range um minimum tensile strength of Mpa Elongation%
1 00—1 50 21 00 2—3 5
1 50—200 1 900 2—3 5
200—350 1 700 2—3 5
5. The chemical composition is carried out according to the national standard GB/T3462-2007 "Mo, Mo and Mo slab" of the technical requirements for implementation.
Index main features are as follows:

GMHI. M 2 and GMHYM. 一3 is a high temperature rare earth lanthanum, yttrium molybdenum, and rare earth elements do not account for impurities.
6. Tolerance
Carried out according to the national standard GB/T4182-2003 "molybdenum wire," the implementation of the relevant technical requirements.
7. Packaging
Molybdenum wires whose diameters are less than 0.4mm are around the dry bakelite or plastic shaft. After the surface is sealed by glazed paper,they are packaged in carton boxes or plastic boxes; molybdenum wires whose diameters are more than 0.4mm are coiled , with moisture-proof wrapping paper or plastic sheeting wrapping them.
8. Storage and transportation
Molybdenum wires should be stored in a dry, relative humidity less than 65% acid-free atmosphere.Moistureproof should be paid attention to during transportation.
