ZHUO HANG XIN is a professional supplier of Molybdenum Rod (Molybdenum Bar). Molybdenum Rod (Molybdenum Bar)we produce are high in electrodes strength and oxidation resistance, and they have long service life and can resist corrosion. Our Molybdenum Rod (Molybdenum Bar) have great metallic performance and balanced inner structure. The surface of the products is smooth and free from scratches, rolling marks, wrinkles, dimples, incisions, discoloration or blemishes of any kind.

Advantage of Molybdenum alloy:

High ductility and toughness

Higher recrystallization temperature (approx. 100 'C)

Better corrosion resistance against molten zinc

Better formability

Excellent strength and mechanical stability at high temperatures (up to 1900°C)

Processing program of molybdenum alloy:

Molybdenum alloy is usually manufactured by powder metallurgy techniques in which Mo powder is hydrostatically compacted and sintered at about 2100°C. Hot working is done in the 870-1260°C range. Molybdenum forms a volatile oxide when heated in air above about 600°C and therefore high temperature applications are limited to non-oxidizing or vacuum environments.

Applications:

 

The highest working temperature where Molybdenum rod can be used in vacuum and environment is 1700℃. Molybdenum rod are widely used as heating elements, outgoing lines and radius rods in high-temperature furnaces. Also, they are used as electrodes and bolts in smelting industry. Other applications include electric vacuum parts, gaseous tubes, electrodes heating in glass industry and wall lamp brackets in lighting industry.

 

 

Surface Finish:

 

Black - Surface is "as swaged" or "as drawn"; retaining a coating of processing lubricants and oxides.

 

Cleaned - Surface is chemically cleaned to remove all lubricants and oxides.

 

Ground - Surface is center-less ground to remove all coating and to achieve precise diameter control.

 

 

Other Description:

 

Sintered Molybdenum Rod (Molybdenum Bar) are high-resistant heating elements. It has high melting point, high purity and high density. At the temperature of 1700℃, it is used in high temperature oxidized environment. Sintered molybdenum rod is mainly used in molybdenum wire drawing and forging.

 

Forged molybdenum rod is now widely used as electric heating elements in lighting industry, electronic industry and semiconductor industry. Forged molybdenum rod can also be used as lamp support, power tube components and the base of silicon rectifier.
