Molybdenum round bar is a strip-shaped material made of molybdenum, which is usually used in industrial applications in extreme environments such as high temperature, high pressure, and high strength, such as in automotive, aerospace, petroleum, and chemical industries.

Molybdenum has excellent high-temperature oxidation resistance, corrosion resistance, and high-strength properties, and is rarely contaminated by radioactivity, so it is also widely used in the nuclear industry. In addition, molybdenum metal is also used to make filaments, electronic components, alloys, etc.

It can be manufactured in different shapes, sizes, and surface qualities according to different processes, the common ones are round, square, hexagonal, etc. The surface can be bright, pickled or polished.

Molybdenum bar is a metal bar made primarily of molybdenum. The following are its characteristics, chemical properties, and physical properties:

1. Feature

High purity, usually 99.95% or higher;
High density, 10.2 g/cm³;
Strong heat resistance, can maintain structural stability at high temperatures;
High mechanical strength, good tensile and bending properties;
Strong corrosion resistance, not easy to be corroded by air, water, and various acid and alkali solutions.

1) Chemical properties

Molybdenum is an inert element, which is not easy to chemically react with other elements;
Molybdenum reacts with oxides, sulfides, nitric acid, and some metals such as copper and iron to form corresponding compounds;
At high temperatures, molybdenum can react with oxygen, nitrogen, hydrogen, carbon, and other elements to form oxides, nitrides, carbides, etc.

2) Physical properties

High melting point, 2610°C;
Small coefficient of thermal expansion, good thermal stability;
High thermal conductivity, more than twice that of steel;
Small resistivity, high conductivity;
Molybdenum has a small hydrogen absorption capacity and is a stable hydrogen absorber.

In general, molybdenum round bar has the characteristics of high strength, heat resistance, corrosion resistance, and high electrical and thermal conductivity, and is widely used in chemical, mechanical, electronic, aviation, and other fields.

Molybdenum bar is an important metal material used in the manufacture of electrodes, vacuum equipment, aerospace, and nuclear industries. The following is its production process and working principle:

2. Production Process

1) Molybdenum powder preparation: use the electrochemical reduction method, hydrogen reduction method, and other methods to convert molybdenum concentrate into molybdenum powder.

2) Powder metallurgy method: the powder metallurgy method is used to extrude the molybdenum powder and then sinter it.

3) Mosaic method: Fill molybdenum powder into a metal tube, heat, and sinter, and then obtain molybdenum rods through stretching, finishing, and other processes.

3. Working Principle

Molybdenum rods are widely used in high temperature environments because of their high-temperature oxidation resistance and mechanical strength. It is mainly used as a material for heating elements, vacuum tube electrodes, molds, etc. At the same time, it also has important applications in the nuclear industry. Due to the low thermal expansion coefficient and good thermal conductivity of molybdenum rods, it can be used to make thermocouples, temperature detectors and heaters, and other equipment, which can withstand high temperature and high-pressure environments.

4. Application Field

Molybdenum round bars can be applied in the following fields:

1) Electronics and semiconductor industry: used in the production of mid-to-high-end electronic products such as chips and flat panel displays.

2) Vacuum melting and heat treatment: It can be used in the vacuum melting and heat treatment industry to manufacture fixed heaters and boats, etc.

3) Optical industry: used in the manufacture of converging mirrors, MPF windows (mid-plane-focusing window), IR Barkhausen windows (IR Barkhausen window), etc.

4) Medical industry: R&D and manufacturing for the manufacture of radiotherapy devices.

5. Package & Transportation

Regarding packaging and transportation, molybdenum rods are usually packed in wooden boxes, wooden boxes, or steel drums, and can be shipped by sea or air.
