Cleaned Molybdenum Wire

Cleaned molybdenum wire is a surface clean, no graphite layer and molybdenum oxide layer molybdenum wire, which has a good high strength, conductivity, cutting speed, long life and other good properties. Cleaned molybdenum wire is usually applied in line cutting field, it usually as vacuum devices, heating elements, refractory matter of high temperature furnace and the parts for electric light source production. In addition, the cleaned molybdenum wire can also be used as a spray molybdenum wire, applied to the wear parts of the car, improving its mechanical wear.
White molybdenum wire also called clean white molybdenum wire, using electrolytic cleaning or hydrogen sintering method to clean graphite coating on molybdenum wire surface and to make the surface bright and glossy. Electrolytic cleaning cleaned molybdenum wire method: this is a cleaning method which uses conducting medium to apply voltage on molybdenum wire and to clean molybdenum wire. And the molybdenum wire will as an electrode and immerse in electrolyte. Hydrogen sintering clean white molybdenum wire method: This method is mainly cleaning metal impurities on the surface of molybdenum wire. Firstly, putting molybdenum wire in vacuum furnace, heating vacuum furnace above 1400 ℃, repeated pass hydrogen into vacuum furnace to make the amount of hydrogen in the furnace reaches 500-10,000 microns, then remove the reaction products which produces by impurities on cleaned molybdenum wire surface and hydrogen.
Cleaned molybdenum wire applications and its performance has a certain relationship between the degree of processing, for example, un-annealed cleaned molybdenum wire and annealed molybdenum wire can as rods, hooks, mandrel and the electrodes applied to different areas, but the performances of them are different, for example, annealed cleaned molybdenum wire elongation is ≤8%; straightness is ≤20 / 200, tensile strength is 1200-2200MPa. On the other hand, un-annealed cleaned molybdenum wire elongation is ≥10%; straightness is ≤ 20/200; tensile strength is 700-1500MPa. The user can select different processing levels’ white molybdenum wire according to application.

Molybdenum Wire



Cleaned Molybdenum Wire
Molybdenum wire is made of high quality molybdenum material by adopting advanced hot and cold drawing crafts. Molybdenum wire can be used as electrode in linear cutting machine to machine workpieces. There are drawing, forging and polished molybdenum wires.

The following are molybdenum wire classifications and molybdenum wire applications:
1. Pure molybdenum wire: pure molybdenum wire can be used as winding wires, supports, outgoing line, heating element, molybdenum foil, wire-electrode cutting, automobile parts spraying.

2. Lanthanum molybdenum wire: lanthanum molybdenum wire is able to be applied as winding wires, glass sealing parts, molybdenum foil, furnace heating materials, high temperature components of wire-electrode cutting, etc..


Molybdenum Cutting Wire
3. Yttrium molybdenum wire: yttrium molybdenum wire can be used as support, outgoing line, electron tube, grid electrode, furnace heating materials, and high temperature components.
 
4. Wire cutting special molybdenum wire: wire cutting special molybdenum wire has such advantages as high strength, good discharge performance, high surface smoothness, fast cutting speed and long service life. Wire cutting special molybdenum wire is used for cutting and machining various non-ferrous metals, iron and steel and magnetic materials.

How to Produce Molybdenum Wire?


Hello, everyone!


Today, we will discuss with you about how to produce molybdenum wire. Welcome to join us.

As we all know that the molybdenum wire is made from molybdenum rod, but what the details  in the process happened?

Cleaned Molybdenum Wire

1. First, testing molybdenum powder, if the powder is qualified then goes on the next step;

2. Mixing-Molybdenum powder;

3. Sintering-sintered molybdenum rod

4. Rolling-molybdenum rod with higher density than sintered;

5. Annealing;

6. Drawing;

7. Annealing;

8. Second drawing-finer wire than pre-drawing;

9. Finished-reach the required diameter;


For different diameter, the wire may be taken several times of drawings.

Properties of molybdenum wire:
Molybdenum wire is featured by high tensile strength, good discharge property, smooth surface, high cutting speed, long service life and low wire tightening frequency.

Do You Know What Is Molybdenum Wire Used For?

Molybdenum Wire

Yesterday, I inspected Chinese version of my mini website which named www.molybdneum-wire.com, and have a better understanding of what is molybdenum wire used for?

Do you know wha is molybdenum?
What property does molybdenum have?
Why do we use molybdenum wire?

Here, I would like to share it with everybody~

Molybdenum is a metal silvery in color with properties that make it one of the most prized industrial metals. It melts at 4,753 degrees Fahrenheit (2,623 degrees Celsius) — one of the highest melting points of any metal — and has the ability to withstand very high pressure and temperature without softening or expanding much.

The above properties of molydbenum make molybdenum wire useful in various products, like automotive and aircraft components, electric vacuum devices, light bulbs, heating elements, and high-temperature furnaces. Molybdenum wire can also be used for printer needles and other printer parts. Depending on what the molybdenum wire is to be used for, it can be made from pure molybdenum, from a mix of molybdenum and other materials such as potassium silicate, or from alloys of molybdenum and other metals, for example tungsten.

Molybdenum wire is often used to make parts that provide structural support, even at very high temperatures. For example, it is commonly used for various furnace components, like heating elements, outlets and windings. Its high melting point makes molybdenum wiresuitable for specialized, high-temperature furnaces featuring hydrogen or vacuum atmospheres.

Another common use for molybdenum wire is as parts for light bulbs. For example, it can be used in the manufacture of supports for lamp filaments made from tungsten, to make leads forhalogen lamp bulbs, and to make electrodes for gas discharge lamps and tubes. This type ofwire is also used in the windshields of airplanes, where it functions as a heating element, providing defrosting. Molybdenum wire is also used in the manufacture of electron tubes and power tube grids.

The surface of the wire can either be clean or coated. Coated wire is black in color, because it is covered in oxides and lubricants. The tensile strength of wire is often an important consideration in manufacturing, and also affects the appearance of the wire: the more tensile strength, the less straight the wire is.

Molybdenum wire commonly comes in sizes from 0.001 inches (0.025 mm) in diameter, to 0.25 inches (6.35 mm) in diameter. Its size can be measured either in inches, or in mils, with 1 mil being equal to one thousandth of an inch. For very thin wire, the size is expressed in the form of weight of a certain length of wire, rather than by diameter.

In addition, molybdenum is similar in appearance to lead, and even received its name from the Greek word for lead, molybdos, because it was often mistaken for lead in ancient times.

Now, do you know what is molydbenu wire used for clearly?
