Molybdenum wire is a kind of consumable made of precious metals such as molybdenum, which is continuously moving with high-voltage electric field to cut the workpiece in WEDM, that is, the continuously moving fine wire in WEDM is called electrode wire (also known as electrode), which can carry out pulse spark discharge erosion and metal forming. Molybdenum wire has many other uses.

High quality high temperature molybdenum raw materials are processed into filaments by hot and cold drawing process, which are used as an electrode in WEDM to process the workpiece.

Molybdenum wire surface state forming process: drawing, forging, polishing

purpose

1. Pure molybdenum wire gmpm-1 is used for winding core wire, bracket, lead wire, heating element, molybdenum foil, wire cutting, automobile parts spraying, etc.

2. La Mo wire gmhi-m-2 is used for glass sealing parts, molybdenum foil, furnace heating materials, wire cutting high temperature components, etc.

3. Yttrium molybdenum wire gmhym-3 is used for bracket, outgoing line, electronic tube spring, grid, furnace body heating material and high temperature components.

4. Gmpm-1 and gmhi-m-2 are used for cutting various non-ferrous metals, steel and magnetic materials. It has the characteristics of high strength, good discharge performance, high surface finish, fast cutting speed and long service life.

Storage attention

Keep the molybdenum wire in a ventilated and cool place with low humidity, and the temperature should be controlled at 20 ℃ ~ 25 ℃ as far as possible to avoid oxidation of the molybdenum wire; if the molybdenum wire is placed for more than 6 months, the problem of poor verticality may occur.

Advantages of molybdenum wire:

The molybdenum wire has high precision, the tolerance of wire diameter is controlled within 0 ～ - 0.002mm, the rate of broken wire is low, the processing speed is high, and it has high cost performance ratio. It can realize stable long-time continuous processing.

The main characteristics of counterfeit molybdenum wire are as follows:

1. The length of each disc of counterfeit wire cut molybdenum wire is short of 100-200 meters or more, and the net weight of molybdenum wire is insufficient.

2. The counterfeit wire cut molybdenum wire tray weighs 120-130g, or the actual tray weighs 20-30g more than the label. The net weight of molybdenum wire increased by 20-30g, and that of some companies was about 98g.

3. The label data outside the box of counterfeit wire cut molybdenum wire is not consistent with the number of labels on the wire reel.

Application of molybdenum wire

Molybdenum wire is used in profile cutting, H2 furnace, heater rod, guide rod hook, mandrel, wire, lead, etc.

Molybdenum is used to manufacture high temperature resistant equipment, such as bracket, guide rod, in furnace heating rod, etc.

Molybdenum wire is mainly used in high temperature thermal field of molybdenum furnace and electronic tube socket. Molybdenum wire is refined molybdenum rod, which is divided into white molybdenum wire, black molybdenum wire, spraying molybdenum wire, wire cutting molybdenum wire, etc. Molybdenum wire is often used as heating material for high temperature furnace, heating wire mesh of support material, etc.
