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.

Molybdenum Bar Or Molybdenum Rod？

A  few days  ago, I asked my collague Sarah who in charge of molybdenum bussiness a question that What Is Molybdenum Bar and What Is Molybdenum Rod? I always can not distinguish molybdenum bar from molybdenum rod cleanly. Now, with the help of Sarah I can do it.

Here, I want to share it with you and wish anyone can give any suggestions or doubt to me in what I mentioned in the following.

What is molybdenum bar and molybdenum rod?

The cross sections of molybdenum bar have many shapes, it may be square, triangular, hexagonal etc., but, if the cross section is round it must be called rod. That to say, the cross section of molybdenum rod must be round and molybdenum bar must not be round.

Also, it may be different in other countries and I would like to listen other voice about it .

Unground Molybdenum Bars

Plus:

Molybdenum bar is one popular product made of molybdenum. Molybdenum rod is one round cross section, and cylinder-shape metal made of molybdenum. Therefore, they shares the properties of molybdenum, which are high melting point, good thermal conductivity and low thermal expansion. At high temperature, they can resist oxidation and have high strength without any distortion during the procession, etc.

They just have different shapes in their cross sections, also have different application. For example, molybdenum bar may be  used as molybdenum electrode or processed into molybdenum wire, and molybdenum rod may be processed into molybdenum disc or used as supporting rod etc..
